Geriatrics is a branch of medical science and social studies that deals with the health, care, and well-being of elderly people, generally those aged 60 years and above (as per Indian classification).
It focuses not only on treatment of diseases, but also on preventive care, rehabilitation, and improvement of quality of life in old age.
From a geographical and demographic perspective, geriatrics is closely linked with:
- Population ageing
- Increasing life expectancy
- Transition towards ageing societies (Stage IV/V of Demographic Transition Model)
With declining fertility and mortality rates, many countries including India are witnessing:
- A rising proportion of elderly population, making geriatric care a key policy concern

Problems Associated with Geriatric Population

The problems of the elderly are multidimensional, involving economic, social, health, psychological, and spatial aspects, which vary across regions and levels of development.

A large proportion of elderly people face:
- Loss of regular income after retirement
- Lack of pension or social security (especially in developing countries like India)
This leads to:
- Economic dependency on family members
- Increased vulnerability to poverty
In agrarian and informal economies:
- Absence of formal retirement systems worsens the situation

Ageing is associated with:
- Chronic diseases such as diabetes, hypertension, arthritis, cardiovascular disorders
- Higher morbidity and disability
Elderly people require:
- Continuous medical care
- Specialized geriatric healthcare services
In many regions:
- Healthcare infrastructure is inadequate
- Accessibility and affordability remain major challenges

Changing family structures (shift from joint to nuclear families) have resulted in:
- Reduced family support
- Increased loneliness among elderly
Migration of younger population to urban areas further leads to:
- “Left-behind elderly” in rural areas
This creates:
- Emotional distress
- Social alienation

Elderly people often suffer from:
- Depression
- Anxiety
- Loss of self-worth
These issues arise due to:
- Retirement
- Loss of spouse
- Reduced social interaction
Mental health among elderly remains:
- Under-recognized and under-treated

In developing countries:
- Limited coverage of pension schemes
- Weak implementation of welfare programs
This leads to:
- Insecurity in old age
- Dependence on informal support systems

Elderly women face double disadvantage due to:
- Longer life expectancy
- Lower economic independence
Issues include:
- Widowhood
- Lack of property rights
- Social neglect

Problems vary spatially:
- Urban areas:
  - Better healthcare but higher cost of living
  - Social isolation due to fast-paced lifestyle
- Rural areas:
  - Lack of healthcare facilities
  - Poor accessibility and infrastructure
Migration patterns create:
- Concentration of elderly in rural areas
- Age-selective migration imbalance

Elderly people are increasingly vulnerable to:
- Physical abuse
- Emotional neglect
- Financial exploitation
Weak legal awareness and enforcement aggravate the problem

Rapid technological advancement has led to:
- Exclusion of elderly from digital services
This affects:
- Access to banking, healthcare, and welfare schemes

India is undergoing a gradual but significant demographic transition towards ageing, where the proportion as well as absolute number of elderly people is increasing rapidly due to:
- Declining fertility rates (TFR ~ 2.0 as per NFHS-5)
- Rising life expectancy (≈ 70+ years; females higher than males)
- Improvements in healthcare, nutrition, and disease control
As per Census 2011, elderly (60+) constituted about 8.6% of the population (~104 million), and recent estimates (LASI / UN) suggest:
- Around 10–11% (~140–150 million) today
- Expected to reach ~19–20% by 2050 (~300 million+), making India an ageing society in absolute terms

Ageing in India shows strong regional disparities:
- Southern States (Kerala, Tamil Nadu, Andhra Pradesh):
  - Advanced demographic transition
  - Higher proportion of elderly (Kerala ~16–18%)
  - Lower fertility and higher life expectancy
- Northern and Central States (Bihar, UP, MP):
  - Younger population structure
  - Lower proportion of elderly but high absolute numbers
This reflects the “South–North divide” in demographic transition, which is crucial for regional planning.

India is witnessing feminisation of ageing, where:
- Women live longer than men
- Higher proportion of elderly women, especially in advanced states
However, elderly women face:
- Higher levels of widowhood
- Limited financial independence
- Greater social and economic vulnerability

Nearly 70% of elderly population resides in rural areas, where:
- Healthcare facilities are inadequate
- Social security coverage is limited
Rural ageing is aggravated by:
- Out-migration of youth, leading to “left-behind elderly”
In urban areas:
- Better healthcare exists
- But elderly face social isolation and high cost of living

A large proportion of India’s workforce is in the informal sector, resulting in:
- Lack of pension or retirement benefits
- Continued economic dependency in old age
Many elderly:
- Continue working in low-productivity jobs
- Depend on family or remittances

India faces a dual burden of disease among elderly:
- Communicable diseases (rural poor)
- Non-communicable diseases (urban elderly) such as:
  - Diabetes
  - Hypertension
  - Cardiovascular diseases
Geriatric healthcare infrastructure is:
- Limited and unevenly distributed
- Lacking specialization at primary healthcare level

Shift from joint family to nuclear family system has led to:
- Weakening of traditional support structures
Migration and urbanization have resulted in:
- Reduced family care
- Increased loneliness and neglect
This has led to:
- Rise of old age homes and institutional care, which were traditionally rare in India
