This document discusses age profile data from the 2011 Indian census. It provides key statistics on India's and Kerala's population distributions by age group. The median age has increased from 2011 to 2021 in both India and Kerala. The proportion of children (0-14 years) has declined while the elderly population (60+ years) has grown. Kerala has the highest percentage of elderly at 12.6% and lowest percentage of children at 7.3%. The document also discusses dependency ratios, demographic dividends, and issues with collecting accurate age data.

2. • Age is one of the core topics in Population Census
• Distribution of population by age is an essential prerequisite for
dissemination of census results by age and for population
projection
• Numbers and percentage of a population within the children
(young) adult (middle aged) and the aged (old) groups determine
population's social and economic structure.
• Census results have three basic tabulation levels, namely,
rural/urban, sex and age.
Importance of Age Data
A person's age
influence what he
needs, buys, does,
and thinks

3. • Children (0-14 years):
• a. They are economically unproductive.
• b. They need food, clothing, education and
medical care.
• Adults (15-59 years):
• a. They are economically productive.
• b. They are biologically reproductive.
• c. They comprise the working population.
• Aged (60 years +):
• a. They are mostly economically unproductive
but some of them are still economically
productive.
• b. They need medical care.
Age is the Most important
viable variable in
demographic analysis

4. AGE :DATA
HIGHLIGHTS

5. • Data on age is collected since the first Census
in1872
• Up to Census 2001, a direct question on age
was recorded
• In Census 2011, for the first time, data on both
date of birth and age has been recorded
• Results on age in Census 2011 have been
compiled based on responses in these two
questions

• Dependency Ratio can be divided in 2 parts:
• Young dependency ratio
• Old dependency ratio
• Dependency Ratio gives the proportion of persons whom the
persons in economically active age group need to support
• Reduction in Dependency Ratio indicates a phase of population
transition where a higher percentage of persons in the working age
group may translate into higher per capita income for the economy
• This is also called the phase where a country may benefit from
‘Demographic Dividend’
