Demographic Trends in India By Charles Minz Moderator- Dr. AbhishekRaut
Framework • Introduction • World Scenario • Stages of Demography • Demographic Transition in India • Fertility Indicators • Mortality Indicators • Sources of Data • Implications of Demographic Transition
Introduction • Demography-It is defined as a Scientific study of human population which includes the study of the changes in a population sizes ,its composition and distribution.
World Population • The World population is the total number of living humans on Earth. As of today, it is estimated to number 7.124 billion. (by the United States Census Bureau ) • Components of Population change. - One birth in every 8 seconds - One death every 12 seconds WORLD POPULATION CLOCK-7,124,004,668
India • India’s population , as on 1st March 2011 stood at 12101.9lakh (6237lakhs males and 5864 lakh females). • India accounts fora meagre2.4%of total world surface area of 1357.9 lakhs sq km
Demographic transition Demographic transition in India from 1901-2011
Sex Ratio • The country has a low sex ratio of 940 female per thousand male, which has shown slight improvement during the last decade.
Fertility indicators • Crude Birth Rate, • General Fertility Rate, • Age Specific Fertility • Total Fertility/Marital Fertility Rates • Gross Reproduction Rate
Crude Birth Rate (CBR) • Crude birth rate = Number of live births during the year ------------------------------------------------ x 1000 Mid-year population
CBR,CDR,NDR • Estimated birth rate declined from 25.8 in 2000 to 22.1 in 2010. • The death rate declined from 8.5 to 7.2 per 1000 population from 2000-2010. • The population, however, continues to grow, as the decline in the birth rate • is not as rapid as the decline in the death rate
General fertility Rate • General Fertility Rate (GFR), a refined measure of fertility, defined as the number of live births per thousand women in the reproductive age-group 15-49 years, is a useful tool for measuring fertility. • General fertility rate(GFR) = Number of live births in a year -------------------------------------- x 1000 Mid-year female population in the age-group (15-49)
Age Specific Fertility Rate Age-specific fertility Rate = Number of live births in a particular age-group --------------------------------------------------------- x 1000 Mid-year female population of the same age-group
Total Fertility Rate • The cumulative value of the age specific fertility rates at the end of the child bearing ages gives a measure of fertility known as Total Fertility Rate (TFR). • TFR indicates the average number of children expected to be born per woman during her entire span of reproductive period assuming that the age specific fertility rates, to which she is exposed to,continueto be the same and that there is no mortality. 45-49 • Total fertility rate(TFR) = 5 x ∑ ASFR 15-19 ---------------------- 1000
Gross Reproduction rate • Another refined measure of fertility which accounts for future mothers is the Gross Reproduction Rate (GRR). • It measures the average number of female children a woman is expected to give birth during her entire reproductive span conforming to the age specific fertility rates (ASFRs) for a given year, if there is no mortality. • Gross Reproduction Rate(GRR)= 45-49 5 x ∑ ASFR for female live birth 15-19 ---------------------- 1000
Estimates of Mortality Indicators • Crude Death Rate (CDR) • Under-five Mortality Rate (U5MR), • Infant Mortality Rate (IMR) • Age Specific Mortality Rates (ASMR), • Still Birth Rate (SBR) and Peri-Natal Mortality Rate (PMR).
Crude Death Rate • Crude death Rate (CDR) = Number of deaths during the year ------------------------------------------ x 1000 Mid Year population
Under 5 Mortality • Under-five Mortality Rate = The under-five mortality is the probability that a child born in a specific year or time period will die before reaching the age of five, subject to current age specific mortality rates. It is expressed as a rate per 1,000 live births.
IMR Infant Mortality Rate has declined considerably (47 i.e. per 1000 Live Births in 2010),
Data Sources • National Census • Civil Registration system • Sample Registration System • Demographic Health Surveys-NFHS,DLHS
Implications of Demographic Transition • Economic Implications • Health Implications • Increase in Longetivity
Economic Implication • The Next two decades will witness- -Increase in 15-59 age group from 519-800 million -Low Dependency Ratio • Challenge is to ensure -Adequate investment in HRD -Appropriate employment. • Opportunity is to -Utilize available abundant human resources to accelerate economic development
Health Implications • Challenge is the massive increase in the number of people of the age group 15-59 -They will need wider spectrum of services • Maternal and child health services • Contraceptive care • Gynecological problems • RTI/STD management • Expect better quality Health services • Opportunity- Their felt needs are meet through RCH programmes
Age group below 15 years • There will be no increase in the numbers .Focus will be to improve on the quality and nutrition services and achieve improvement in Health and Nutrition status • Improve access to education and skill development • Improve access to immunization services. • Improve quality health care to vulnerable adolescent.
Implications in Increase in Longetivity • As many as 70% of the aged depend on others for existence. • Situation still worse for elderly women.85-87% economically dependent • Common geriatric problems • Five most common cause of death in elederly-Bronchitis,pneumonia,IHD,stroke ,cancer and TB
