Functional Classification of Towns and Cities

Functional Classification

• The functional classification of settlements organises towns and cities on the basis of the dominant economic activities they perform — manufacturing, trade, administration, defence, education, religion, recreation, and so on.
• It is widely regarded as the most realistic and meaningful basis for classifying urban settlements because it is with respect to economic activities that urban centres vary most considerably from each other.
• Settlements may be classified on many bases — population size, location, spatial pattern, or historical origin. But none of these reveals why a settlement exists, what role it plays in the regional and national economy, or what services it provides to its hinterland. Functional classification answers these questions directly.
  • The physical form and social character of any settlement is largely determined by the type and complexity of functions it performs.
  • Cities are usually multifunctional and differ greatly from towns with fewer functions, or from villages with even fewer.
  • As settlements grow in size, they become more complex and multifunctional – making clear-cut functional categorisation increasingly difficult.
  • The main challenge in functional classification is assigning each settlement to a specific group – the criteria used, functions considered, and interpretations applied are all value judgements of the scholar, introducing some degree of subjectivity.
  • Since urban settlements offer a wider range of functions, most scholars have focused their classification efforts primarily on urban centres rather than rural ones.

Methods of Functional Classification

Since the last forty years of the twentieth century, the schemes of functional classification have become progressively more comprehensive and statistically sophisticated. Three broad categories of methods have been developed:

Category	Nature	Key Scholars	Basis	Limitation
Qualitative Methods	Empirical, non-statistical	Aurousseau (1921), Griffith Taylor (1949), Mumford (1938)	Personal observation and description	Subjective; no standard criteria; country/time specific
Qualitative-cum-Quantitative	Transitional; uses occupational data but arbitrary thresholds	Harris (1943), Ogburn (1937)	Census occupational and employment data	Qualifying percentages arbitrarily chosen
Quantitative (Statistical)	Purely statistical; objective and replicable	Nelson (1955), Webb (1959), Pownall (1953), Alexandersson (1956)	Standard deviation, location quotient, surplus workers index	Requires substantial reworking for application outside original country

1. Qualitative Methods — The Empirical Stage

• Qualitative methods constitute the initial stage in functional analysis of settlements. They are empirical and non-statistical — based on the direct observation and descriptive judgement of the scholar.
• Though subjective and now considered inadequate as standalone tools, these methods provided the conceptual scaffolding upon which later statistical methods were built.

Aurousseau’s Classification (1921) — The First Major Scheme

• Marcel Aurousseau, in his paper “The Distribution of Population — A Constructive Problem” (Geographical Review, Vol. XI, 1921), was the first scholar to systematically classify towns by function.
• He proposed six broad classes further subdivided into 28 sub-types:

Class	Sub-Types
I. Administration	Revenue Towns, Capital Cities
II. Defence	Garrison Towns, Naval Bases
III. Culture	University Towns, Cathedral Towns, Art Centres, Pilgrimage Centres, Religious Centres
IV. Production	Manufacturing Towns, Collection (Mining, Fishing, Forest, Depot Towns)
V. Communication	Transfer (Market Towns, Fall Line Towns, Break-of-Bulk Towns, Bridgehead Towns, Tidal Limit Towns, Navigation Head Towns), Distribution (Export, Import, Supply Towns)
VI. Recreation	Health Resorts, Tourist Resorts, Holiday Resorts

Merits of Aurousseau’s Classification

• First comprehensive scheme bringing diverse ideas into one framework — provided the “springboard for new methods” of functional classification.
• Simple, intuitive, and easy to apply without complex statistical tools.
• Covers a wide range of urban functions including cultural, recreational, and defence roles often ignored in purely economic classifications.

Criticisms of Aurousseau’s Classification

• Over-generalised — the six classes are too broad to capture the nuanced differences between cities.
• To classify a town into one major category, the cut-off point of one class has been decided by an arbitrary percentage, and therefore, it is subjective.
• Some classes are specific to particular countries at particular points of time — e.g., “Fall Line Towns” and “Break-of-Bulk Towns” were characteristic of early 20th century USA and rare elsewhere.
• Neglects economic activities entirely — makes no use of occupational or employment data.
• Mixes functional and locational terms — for example, “Tidal Limit Town” grouped under communication is a locational term, not a functional one.
• Purely based on personal observation — different scholars applying the same scheme may reach different conclusions for the same city.

2. Qualitative-cum-Quantitative Methods — The Transitional Stage

• These methods mark a transitional stage between the earlier purely qualitative methods and the later purely statistical ones.
• They use occupational and employment data from census records — establishing a clear link between settlement functions and occupational groups — but the qualifying thresholds and minimum limits are often selected arbitrarily by the scholar, retaining an element of subjectivity.

Ogburn’s Classification (1937)

• One of the earliest attempts to introduce quantitative data into functional classification.
• Classified towns on the basis of the percentage of population engaged in trade, manufacturing, and transportation.
• Primarily descriptive; percentages used were not rigorously derived from statistical analysis.

C.D. Harris’s Classification (1943) — The Most Widely Accepted in This Category

• Chauncy D. Harris presented “A Functional Classification of Cities in the United States” published in the Geographical Review in 1943. This remains the most widely accepted method in the qualitative-cum-quantitative category.
• Based on his study of 984 towns with populations of 10,000 and above in the United States, using 1930 Census data.
• Harris relied on two sets of information: occupation figures (what people say they do) and employment figures (what establishments say they employ).
• He preferred employment figures to occupation figures — to avoid including informal workers such as carpenters and plumbers in the manufacturing category.
• He identified nine principal categories of towns.

• Harris’s classification suffers from some defects and is not universally viable. He used metropolitan districts as functional units because the industry-group data, such as those published now, were not available during that time. Consequently, the number of cities that were too small to have metropolitan districts was left unclassified.
• Carter (1975) labelled Harris’s classification as subjective because the decisions to access or delete with a minimum number or cut-off points seem to be personal ones and were set by simple empirical means.
• Under the class of ‘Transport and Communications’, workers engaged in telephone and telegraph services were omitted, which was nothing more than a subjective decision

3. Quantitative (Statistical) Methods — The Rigorous Stage

• In quantitative methods, the pre-determined minimum level of specialisation is not chosen arbitrarily but derived from statistical techniques, making the classification objective, transparent, and replicable by other scholars. These methods are based on the concept of Diagnostic Ratio — the idea that a certain proportion of the labour force in any function, above which that employment becomes distinctively specialised compared to other urban centres.

Howard Nelson’s Classification

• Nelson, through his classification, removed the shortcomings of the earlier classifications by using a stated procedure that could be objectively checked by other workers.
• His paper ‘A Service Classification of American Cities’ was published in the journal ‘Geography’ in 1955. He decided to base his method of classification entirely upon major industry groups as listed in the 1950 Census of Population for standard metropolitan areas, urbanised areas, and urban places of 10,000 or more population.
• He omitted the little significance groups like agriculture and construction, and finally, arrived at the nine activity groups
  1. manufacturing;
  2. mining
  3. retail;
  4. wholesale;
  5. personal service;
  6. professional services;
  7. public administration;
  8. transport and communication;
  9. finance, insurance, real estate.
• The problem of city specialization, and also the degree of specialization above the average was solved by giving margins of the different degrees to different size classes.
• He did find a definite tendency for the percentages employed in some activities to vary with city size. The question – ‘When is a city specialized?’ was solved by using a statistical technique – the Standard Deviation (SD). [S.D=√d²/N]
• With the help of the above formula, the index value is derived and the lowest deviation from theoretical value projects the city character on the basis of economic functions.
• Percentage of workers in all functions were calculated for each town and then the statistical mean of each function was calculated and towns having percentage above mean functions were taken as specialized towns in that function.
• Thereafter, towns having below the mean were eliminated and the remaining towns were hierarchically arranged on the basis of standard deviation.
• Nelson has not only functionally classified the cities but also taken the functional hierarchy for each function.
• According to Nelson, the city can be specialized in more than one activity and to varying degrees.

Criticism

• Nelson was criticized by some British Urban geographers especially Moser and Scott who said that this scheme of classification is applicable only for a particular point of time. After few years, there may be a change in occupation statistics. But, a simple change in occupational statistics can’t change the genetic factors of the town.

Functional Types of Urban Centres

Of all classifications of urban settlements, the one based on function is the most realistic and meaningful. The following are the major functional categories of urban centres as recognized in settlement geography literature:

1. 🏛Administrative Towns
   • Administration is the dominant function. These towns are the headquarters from where a country, state, district, or specific territory is administered.
     • May be national capitals, state capitals, district HQs, or sub-divisional HQs
     • Contain government offices, public buildings, residences of ministers and bureaucrats
     • Economic base heavily dependent on government employment
     • Indian examples: New Delhi (national), Jaipur (state), Bhopal, Patna, Lucknow
     • Global examples: London, Washington D.C., Moscow, Cairo, Tokyo
2. 🏭Industrial Towns
   • Manufacturing and production of goods is the main function. Manufacturing industries act as centripetal forces for growth.
     • Scale and types of industries determine the size and structure of the town
     • Major share of working population engaged in manufacturing
     • Generally well connected by rail-road network for raw material supply and product distribution
     • Indian examples: Jamshedpur (Tata Steel), Bokaro, Bhilai, Asansol, Bhadravati
     • Global examples: Chicago, Detroit, Glasgow, Shanghai, Manchester
3. 🏪Commercial Towns (Trade Centres)
   • Collection and distribution of commercial goods is the main function. Well connected by transportation systems. Three sub-types:
     • Market towns: Retail and wholesale trade. Ex: Kanpur, Ludhiana, Indore, Bhopal
     • Financial towns: Financial houses, banks, stock markets, commercial agencies. Ex: Mumbai — financial capital of India
     • Seaports: Export and import; some function as entrepôts with large warehouses. Ex: New York, Amsterdam, Cape Town, São Paulo
4. 🚂Transport Towns
   • Predominantly perform the function of transport and communication.
     • Generally develop at convergence of roads (highways) or at railway junctions
     • Economy sustained by the traffic of people and goods passing through
     • Global examples: San Francisco, Paris, Berlin, Santiago, Sydney
     • Indian examples: Nagpur (all national highways converge), Itarsi (major rail junction, MP), Mughalsarai
5. ⛏Mining Towns
   • Involved in the mining of precious metals, minerals, or energy resources.
     • Located in proximity to mineral extraction sites
     • Highly vulnerable to boom-and-bust cycles when resources are exhausted
     • Indian examples: Jharia, Raniganj (coal), Kolar (gold), Digboi (oil — Asia’s oldest refinery), Zawar (zinc)
     • Global examples: Hunnan, Shanshi, Kirkuk, Kalgoorlie
6. 🎓Educational Towns (University Towns)
   • Dominant function related to education and training.
     • Have one or more universities — called university towns
     • Also include colleges, medical colleges, engineering colleges, training institutes
     • Population drastically reduces during holidays — a unique diagnostic feature
     • Indian examples: Aligarh (AMU), Shantiniketan, Pilani (BITS), Amravati
     • Global examples: Oxford, Cambridge, Harvard
7. 🕌Religious Towns
   • Existence entirely based on religious significance; generally develop at holy places or pilgrimage sites.
     • Characterized by temples, mosques, churches, gurudwaras
     • Periodically visited by vast crowds from long distances — creating a pilgrimage economy
     • Indian examples: Kashi/Varanasi, Dwarka, Haridwar, Tirupati, Madurai, Bodh Gaya
     • Global examples: Mecca, Jerusalem, Vatican City
8. 🛡Military Towns (Defence Centres)
   • Primarily concerned with defence or military services.
     • Usually situated near places of strategic importance
     • Clear division of land between military and civil authorities — military campus at a distance from main town or at its corner
     • Characterized by cantonments, barracks, airfields, training areas
     • Indian examples: Ambala, Meerut, Jodhpur, Port Blair, Pune Cantonment, Visakhapatnam
     • Global examples: Gibraltar, Aden
9. ✈Resorts and Recreation Towns
   • Cater to the recreational needs of people.
     • Located near hot springs, hill stations, seaside, historical monuments, national parks, or scenic beauty
     • Have hotels, shopping facilities, cinemas, nightclubs, and children’s parks
     • Indian examples: Srinagar, Pahalgam, Gulmarg, Manali, Darjeeling, Ooty, Agra, Jaipur
     • Global examples: Geneva, Los Angeles, Venice, Barcelona, Las Vegas
10. ⚡Diversified Towns
    • Multifunctional with absence of any one particular dominant function.
      • First identified and named by Harris (D) and Nelson (D) in their quantitative schemes
      • The most common functional type among large cities globally
      • The Indian urban system is fundamentally a system of diversified towns — most large cities exhibit highly balanced functions with no clear specialisation
      • Examples: New York, Chicago, Kansas City, Mumbai, New Delhi, Hyderabad, Kolkata

Functional Classification of Indian Cities

• A classification system devised for American or European cities cannot be applied to the Indian context without substantial modifications. Several important contextual differences must be noted before examining the Indian classification schemes:
  • In the Indian context, primary activities are very much characteristic of urban centres — unlike the assumption in Western classification methods that primary activities are entirely rural. Almost a third of India’s urban centres have agriculture as a relatively dominant activity.
  • Employment in agriculture is significant primarily in small towns; in large cities, secondary and tertiary activities predominate.
  • The occupational data provided by the Indian Census forms the primary basis of all Indian functional classification schemes.
  • According to the Indian Census, towns can be classified into five functional categories: primary activities, industry, trade and commerce, transport, and services.

Indian Census Classification Framework

Category	Criterion	Classification
Monofunctional	Workers in ONE category ≥ 40% of total workers	Town dominated by that single function
Bifunctional	Workers in TWO dominant categories combined ≥ 60% of total workers	Town has two significant functions
Multifunctional	No two categories combined yield 60%	Diversified town with no dominant function

Historical Progression of Indian Classification Attempts

Scholar	Year	Method	Scope	Key Contribution / Limitation
Amrit Lal	1951	Location Quotient + Median	67 Class-I cities (1951 Census)	First attempt; methodological deficiencies; didn’t even list the 67 cities studied
Janaki	1954	Descriptive/qualitative	Towns of Kerala	Five categories: administrative, commercial-industrial, agricultural, market, temple, plantation towns. Descriptive; no statistical criteria
Prakash Rao	1962	Least Square Linear Regression	All Indian towns	Plots population size vs % workers in a function; line of central value determines specialisation; innovative but complex
Rafiullah	1965	Maximum Positive Deviation	Indian towns (1961 Census)	Adaptation of Weaver’s crop combination method; calculates deviation from middle value of theoretical standard
Ganguli	1965	Nelson’s Standard Deviation Method	250 Indian cities with 50,000+ population (1961 Census)	Direct application of Nelson’s method to India; one of the earliest rigorous quantitative attempts
Qazi Ahmad	1965	Multivariate Analysis (62 variables)	102 Indian cities with 1 lakh+ population	Only 10 cities exhibited over 70% correlation among variables — revealing the limits of multivariate methods for India
Ashok Mitra	1964/1973	Triangular Method	2528 urban centres (1961 & 1971 Censuses)	Most widely accepted method; simple, specific logic; triangular graph for visual representation
Mitra, Mukherjee et al.	1981	Factor Analysis + Cluster Analysis	1466 towns (1961 & 1971 Census data)	24 cluster types; computationally complex; results not significantly better than 1964 method
M.K. Jain	1991/1994	Modified Ashok Mitra method	All urban agglomerations (1991 Census)	Added mono-, bi-, multi-functional categories; 5 sectors including primary activity

Most Common Functional Classification of Indian Cities

The most common functional classification of the Indian cities is –

1. Administrative Cities
2. Defense Towns
3. Cultural Cities
4. Collection Centres
5. Production Centres
6. Transfer and Distribution Centres
7. Resorts Towns
8. Residential Towns
9. Seaport Towns
10. Cities with Diversified Functions

Administrative Cities

• The main function of the administrative cities/towns is to administer the country, state, or any other administrative unit. It includes not only the capital cities of the country but also all the centers of states, districts, and other administrative divisional headquarters of the country. In the administrative cities are placed the legislative, executive, and judiciary of the respective administrative unit.
• Example: New Delhi, Mumbai, Kolkata, Chennai, Bangalore, Hyderabad, Lucknow, Jaipur, Patna, Bhopal, Chandigarh, Aizawl, Kohima, etc. are essentially administrative cities.

Defense Towns

• The dominant functions in a defense town pertain to the security and defense of the country. In fact, such towns are characterized by cantonments, barracks, military training centers, garrisons, air-force bases, airfields, harbors, strategic locations, and naval headquarters.
• Example: Adampur, Ambala, Halwara, Jalandhar, Jamnagar, Jodhpur, Khadakwasla, MOHO, Pathankot, Udhampur, Vishakhapatnam, etc. are some of the examples of defense towns.

Cultural Cities

• These cities perform either religious, educational, or recreational functions.
  • Educational: They are characterized by universities, college buildings, libraries, and playgrounds. They also have shops which mainly catch to the needs of the students, such as book shops, sports shops, etc.
    • Example: Shantiniketan, Aligarh, Gurukul, Kharagpur, etc.
  • Entertainment: Such towns are known for their theaters, art galleries, and other cultural activities as that of film making.
    • Example: Mumbai, Chennai, Kolkata, etc.
  • Religious: Religious towns can be centers of pilgrimage on the seats of religious leaders. They are characterized by religious monuments, shops of selling religious books, pictures, candles, agarbattis, etc.
    • Example: Allahabad, Amritsar, Ajmer, Bodh-gaya, Dharamshala, Gangotri, Hardwar, Pushkar, Varanasi, etc.

Collection Centres

• The mining towns, fishing ports, lumbering centers are included in this category. The exploitation of minerals from the mines is the main function of the mining towns.
• Example: The urban places of Jawar near Udaipur, Digboi in Assam, Ankleshwar in Gujrat, Bailadila in Chhattisgarh; Kathgodam, Halwani, Kotwar in Uttarakhand, Machlipatnam, Kakinada, Mahe, Kozhikode, etc. are some of the examples of collection centers.

Production Centres

• The urban places having manufacturing industries are included in the category of manufacturing cities. These cities are well connected by roads and railways.
• Example: Bhilai, Bhadrawati, Bokaro, Coimbatore, Dhanbad, Durgapur, Jamshedpur, Vishakhapatnam, etc. are some of the important manufacturing centers of India.

Transfer and Distribution Centres

• The main functions performed at the transfer centres are trade, commerce, and services. The market towns are characterized by markets containing a wide range of goods, stores, warehouses godowns, cold storage, and wholesale markets supported by a good network of transport facilities.
• Example: The most important commercial centers are Mumbai, Kolkata, Chennai, Ahmadabad, Gwalior, Indore, Ludhiana, Muzaffarpur, Surat, etc.

Resorts Towns

• The urban places which accommodate the recreation needs of people are known as resorts or recreation
  towns. These towns may be based on health-giving water (hot-spring), seaside recreation, mountain-climbing, sports facilities, national parks, tiger reserves, and places of aesthetic beauty. Resort towns are also characterized by hotels, guest houses, cinema halls, nightclubs, shopping centers, etc.
• Example: Dehra-dun, Dalhousie, Darjeeling, Dharamshala, Gulmarg, Kullu, Manali, Mt. Abu, Nainital, Pahalgam, Panchmadhi, Ooty, Ranikhet, etc. are some of the examples of resort towns.

Residential Towns

• Some of the towns and cities are developed just to provide residential accommodation to the urban people. Modern towns are usually located away from congested cities and provide residential facilities for the urban people.
• Example: Delhi, Rohini, Indirapuram, New Delhi, Mumbai, Kolkata, Bangalore, Hyderabad, Lucknow, Jaipur, etc. are some examples of residential towns.

Seaports

• The basic task of seaports is to export and import goods.
• Example: Diamond Harbour, Haldia, Kandala, Kochi, New Mangalore, New-Tuticorin, Okhla, Paradeep, etc. are some examples of Seaport towns in India.

Cities with Diversified Functions

• As stated, most of the cities and towns of India are multifunctional. The capital cities are also the commercial, manufacturing, cultural and recreational centers. The seaports are engaged in trade and commerce, besides cultural activities.
• Example: New Delhi, Mumbai, Kolkata, Bangalore, Hyderabad, Lucknow, Jaipur, Allahabad, etc. are some examples of multifunctional cities of India.

Ashok Mitra’s Classification (1964)

Ashok Mitra (Registrar General and Census Commissioner of India at the time) designed the most widely accepted method for explaining the functional structure of Indian towns and cities. First published as a classification in 1964 and as a full monograph in 1973, it used 1961 Census data providing nine categories of workers for all urban centres.

Step 1 — The Nine Census Categories

Category	Description	Urban/Non-Urban?
I	Cultivators	Non-urban (excluded from analysis)
II	Agricultural Labour	Non-urban (excluded from analysis)
III	Forestry, Fishing, Plantations, Mining and Quarrying	Both (borderline — mining is urban, forestry/fishing generally not)
IV	Household Industry	Urban
V	Manufacturing other than Household Industry	Urban
VI	Construction	Urban
VII	Trade and Commerce	Urban
VIII	Transport, Storage and Communication	Urban
IX	Services	Urban

Categories I and II (agriculture) are entirely non-urban and were excluded. The remaining seven categories (III–IX) were grouped into three broad functional types:

Functional Type	Census Categories Included	Classification Criterion
A — Manufacturing Towns	III + IV + V + VI	% workers in A > % in B or C (by 20%)
B — Trade and Transport Towns	VII + VIII	% workers in B > % in A or C (by 20%)
C — Service Towns	IX	% workers in C > % in A or B (by 20%)

Step 2 — Six Sub-Types

Manufacturing Towns and Trade & Transport Towns were further subdivided into sub-classes, yielding six types in total:

Class	Sub-Class	Criterion
Manufacturing Towns (A)	a. Mining/Forestry/Fishing/Plantation Town	% workers in Category III > IV, V, or VI considered individually (by 10%+)
	b. Artisan Town	% workers in Category IV > III, V, or VI considered individually (by 10%+)
	c. Manufacturing Town	% workers in Category V > III, IV, or VI considered individually (by 10%+)
	d. Construction Town	% workers in Category VI > III, IV, or V considered individually (by 10%+)
Trade & Transport Towns (B)	a. Trade Town	% workers in Category VII > Category VIII (by 10%)
	b. Transport Town	% workers in Category VIII > Category VII (by 10%)

Step 3 — The Triangular Method (Visual Representation)

To determine the degree of functional specialization, Mitra devised a brilliant visual tool: the triangular graph method.

• An equilateral triangle is drawn, with three medians (axes) representing Manufacturing (A), Trade & Transport (B), and Services (C).
• Each median is graduated from 0 to 100. The values of A, B, C for any town always add up to 100%.
• The town’s position is plotted in the triangle. The in-centre (where all three medians meet) represents a town where each function has exactly 33⅓% workers — maximum diversification, no specialization.
• Three concentric circles are drawn from the in-centre at radii of 6⅔, 11⅔, and 16⅔ units, intersecting the axes at 40%, 45%, and 50% marks.

Code	Degree of Specialisation	Position in Triangle	Worker %
FHD	Functions Highly Diversified (High Balance)	Within the 1st (inner) circle	No group exceeds 40%
FMD	Functions Moderately Diversified	Between 1st and 2nd circles	One group = 40%–45%
PFA	Predominant Function Accentuated (Moderately Specialized)	Between 2nd and 3rd circles	One group = 45%–50%
PFHA	Predominant Function Highly Accentuated (Highly Specialized)	Outside the 3rd (outer) circle	Dominant group > 50%

The six subtriangles within the main triangle further determine the predominant and subsidiary functions. For example, a city positioned in subtriangle IV between the second and third circles is a specialized industrial city with medium trade & transport functions and low service functions.

The 1981 Classification — Mitra, Mukherjee and Others

• Used factor analysis + distance analysis + hierarchical cluster analysis — computationally intensive, requiring computer assistance.
• Based on a data matrix of 1,466 towns × 9 worker categories for both 1961 and 1971 Census data.
• Results showed 24 cluster types — but these did not always correspond between the 1961 and 1971 analyses (cluster 8 in 1961 = very high transport; cluster 8 in 1971 = high trade).
• Despite the computational complexity, the final classification results did not vary significantly from the simpler 1964 method.
• Conclusion: The brief and simple 1964 triangular method remains the better practical tool.

M.K. Jain’s Classification Based on 1991 Census

Dr. M.K. Jain, Deputy Registrar General (SS) of India, attempted a functional classification of Indian cities following Ashok Mitra’s methodology, using the 1991 Census data. His classification (published as Census of India 1991 Occasional Paper No. 3, 1994) added three new functional classes: mono-functional, bi-functional, and multi-functional.

Method — Five Sectors

The nine industrial census categories were grouped into five sectors:

Sector	Census Industrial Categories Included
1. Primary Activity	I (Cultivation), II (Agricultural Labour), III (Forestry/Fishing/Mining), IV (Household Industry)
2. Industry	V (Manufacturing), VI (Construction)
3. Trade	VII (Trade and Commerce)
4. Transport	VIII (Transport, Storage & Communication)
5. Services	IX (Services)

Classification Decision Rules

• Mono-functional: Workers in ONE sector ≥ 40% of total main workers.
• Bi-functional: No single sector ≥ 40%, but the two largest sectors combined ≥ 60% of total workers.
• Multi-functional: No two sectors combined ≥ 60% — the town is diversified.
• Additional sub-functional categories were recognized where at least 25% of workers were engaged in: (a) forestry/fishing, (b) mining/quarrying, (c) household manufacturing, or (d) construction.

Functional Classification of Million Cities of India — M.K. Jain (1991 Census)

#	Urban Agglomeration	Population	Functional Category
1	Bombay (Mumbai)	12,596,243	IND (Industry dominant)
2	Calcutta (Kolkata)	11,021,918	IND-cum-TR and COM
3	Delhi	8,419,084	Services-cum-IND
4	Madras (Chennai)	5,421,985	IND-cum-Services
5	Hyderabad	4,344,437	IND-cum-Services
6	Bangalore (Bengaluru)	4,130,288	IND
7	Ahmedabad	3,312,216	IND
8	Pune	2,493,987	IND
9	Kanpur	2,029,889	Services-cum-IND
10	Nagpur	1,664,006	IND-cum-Services
11	Lucknow	1,669,204	Services
12	Patna	1,099,647	Services
13	Vizag (Visakhapatnam)	1,057,118	Services-cum-IND
14	Jaipur	1,518,235	IND-cum-Services
15	Surat	1,518,950	IND
16	Kochi	1,140,605	IND-cum-Services-cum-TR and COM

Key Observation from M.K. Jain’s 1991 Classification

The most striking finding is that Industry (IND) dominates as the primary or secondary function in virtually all million-plus cities. Only Lucknow and Patna are classified as purely service towns. Delhi — the national capital — is classified as Services-cum-IND, confirming that its administrative function is reflected as the service sector but manufacturing remains significant. Mumbai’s classification as purely IND reflects the dominance of its textile, chemical, and port-related industries in the 1991 data.

Cultural Classification of Indian Cities

Beyond economic function, Indian cities can also be classified on the basis of cultural and historical character — reflecting the different civilizational phases that have shaped their morphology, architecture, and social fabric. Five broad cultural types have been identified:

Cultural Type	Key Characteristics	Indian Examples
Ancient Cities	Relics of ancient urbanization — ruins, religious structures, organic street patterns; morphology shaped by ritual, caste, and temple-centred planning	Rajgir, Madurai, Varanasi, Mathura, Thanjavur, Kanchipuram, Pataliputra (Patna)
Medieval Cities	Turkish and Mughal architecture — bagh (gardens), fountains, ornate arches, domes; fortified but gates remain; old city has ethnic enclaves and congested bazaars	Agra, Delhi (Shahjahanabad), Jaipur, Pune, Surat, Nabadwip, Mysore, Lucknow
Colonial Cities	Gothic and Doric architecture in public buildings; civil lines, cantonments, railway colonies; clear separation of European and native quarters	Mumbai (Bombay), Kolkata (Calcutta), Chennai (Madras), Ranchi, Shimla, Dehradun, Darjeeling
Industrial Age Cities	First modern planned cities in British period; neat road grids, standardized workers’ housing; few in number but distinct in character	Jamshedpur, Asansol, Kulti, Bhadravati, Rourkela, Durgapur, Bhilai
Post-Independence Planned Cities	Designed by leading architects; grid-sector layouts; pollution-free green belts; separate residential sectors; market complexes	Chandigarh (Le Corbusier), Bhubaneswar, Gandhi Nagar, Naya Raipur, Bokaro

Classification by Stages of Growth and Decay

Griffith Taylor’s Sequential Stages

Following W.M. Davis’s theory of sequential landscape change, Griffith Taylor (1949) identified stages in urban development. However, he himself acknowledged that the model is applicable only to Western cities under a particular economic system and lacks specific determinants:

• Sub-infantile: Initial cluster — a single ill-defined street town. No clear zones.
• Infantile: No clear differentiation between industrial, commercial, and residential areas. No factories. Larger houses near margins.
• Juvenile: Fairly clear segregation of a commercial quarter towards the centre. Residential areas still undifferentiated.
• Adolescent: Clear differentiation of residential zones begins.
• Early Maturity: Residential differentiation more pronounced.
• Maturity: Separate commercial areas and four clearly differentiated residential zones — from mansions to shacks.

The classification is interesting from an academic point of view but is unpractical as no specific determinants have been stated. Moreover, it is applicable only to western cities under a particular economic system.

Lewis Mumford’s Growth-Decay Typology (1938)

Lewis Mumford in his landmark work The Culture of Cities (1938) conceived of a city rising through multiple stages to reach its evolutionary peak — and then beginning to decay. He identified three stages of growth followed by three stages of decay:

Stage	Type	Characteristics	Examples
Growth 1	Eopolis	The rising village community — pre-urban, primarily agricultural	Early settlements
Growth 2	Polis	Small market town; modern civic amenities emerge while traditional values are upheld	Medieval English market towns
Growth 3	Metropolis	Large city with cosmopolitan population, specialized occupations, and wide sphere of influence	Plato’s Athens, Shakespeare’s London, Tagore’s Calcutta, Emerson’s Boston
Decay 1	Megalopolis	Bloated city where material wealth dominates life; beginning of decline	Rome (2nd century), Paris (18th century), New York (20th century), Calcutta (late 20th century)
Decay 2	Tyrannopolis	Tyrannical city — moral apathy replaces good living; commerce alternates between expansion and depression	—
Decay 3	Nekopolis	The “city of the dead” — overcrowding and degradation lead to famine and war	Ancient Babylon, Nineveh, Rome

Mumford’s Techno-Economic Phases (Based on Geddes)

• Eotechnic Phase: Wind, water, and wood as chief energy sources; beginning of decline of manual labour. Medieval period cities.
• Paleotechnic Phase: Era of coal and steam energy. Cities became increasingly polluted and dirty — the industrial revolution city. Ex: Victorian Manchester, early Kolkata.
• Neotechnic Phase: Electricity as the main energy source; cities become cleaner; synthetic materials; advanced communications; faster travel.
• Biotechnic Phase: Harmony between human beings and nature; production systems aim to maintain a clean and beautiful environment. Mumford in 1938 declared this was “just becoming visible over the edge of the horizon.”

Robert Redfield’s Cultural Classification (1954)

Redfield divided cities on the basis of two historic periods — before and after the Universal Oikumene (the Industrial Revolution/Western expansion):

• Pre-industrial: (i) Administrative Cultural Cities — cities of indigenous bureaucracy and literature (e.g., Peiping, Lhasa, Kyoto, Allahabad); (ii) Cities of Native Commerce — cities of the entrepreneur (e.g., Marseilles, early Canton).
• Post-industrial: (i) Metropolis — cities of the worldwide managerial and entrepreneurial class (e.g., London, New York, Mumbai); (ii) Cities of Modern Administration (e.g., Washington D.C., New Delhi).
• These classes form the basis of Redfield’s concept of orthogenetic urbanization (cities growing from within the indigenous culture) vs heterogenetic urbanization (cities shaped by external forces — colonial, trading).
