Sample Registration System (SRS), Features, Data & Importance in India

The Sample Registration System is a system used to collect information about births, deaths, and population changes in a country. It helps in understanding how the population is growing and what trends are taking place over time. It works by collecting data from selected sample areas and gives regular and reliable estimates of vital statistics. This is especially useful in places where complete records of births and deaths are not properly maintained.

About Sample Registration System (SRS)

• The Sample Registration System is a demographic survey system used to provide reliable yearly data on important indicators like infant mortality rate, birth rate, death rate, and other fertility and mortality measures at both national and regional levels.
• It was first started on a pilot basis in 1964-65 by the Registrar General of India in a few states, and later became fully operational in 1969-70 across the country.
• The system works through continuous recording of births and deaths in selected sample areas. This work is done by local part-time enumerators, who are usually Anganwadi workers or school teachers.
• In addition to this, there is an independent survey conducted every six months by SRS supervisors to collect the same information again.
• Finally, the data collected by both the enumerators and supervisors is matched and verified, which helps in improving the accuracy and reliability of the data.

Sample Registration System (SRS) Key Features

• The Sample Registration System is designed to provide accurate and timely data on important population indicators such as birth rate, death rate, fertility rate, infant mortality rate (IMR), and maternal mortality ratio (MMR) at both national and state levels.
• It follows a dual record system, where births and deaths are recorded continuously by a local enumerator, and the same information is collected again through an independent survey every six months to ensure better accuracy and verification.
• The system has wide coverage, as it collects data from a large sample population (millions of people) across different states and union territories, making the estimates more reliable and representative.
• SRS regularly publishes reports and bulletins, which provide updated information on demographic trends such as fertility, mortality, and population growth. These reports are widely used by researchers and government agencies.
• It plays an important role in policy making and planning, as the data helps the government to assess the effectiveness of health programs, family planning measures, and population control policies.
• SRS data is also useful for tracking progress in social development, especially in areas like maternal and child health, nutrition, and life expectancy.

SRS Statistical Report 2023 Key Findings

• The Sample Registration System Statistical Report 2023 shows important changes in fertility and mortality trends in India.
• Total Fertility Rate (TFR):
  • TFR declined to 1.9 in 2023, which is below the replacement level (2.1).
  • Highest TFR: Bihar (2.8)
  • Lowest TFR: Delhi (1.2)
  • TFR means the average number of children a woman is expected to have during her reproductive years (15-49 years).
• Replacement Level Fertility:
  • It is the level at which a population replaces itself from one generation to the next (around 2.1 children per woman).
• Crude Birth Rate (CBR):
  • Declined from 19.1 (2022) to 18.4 (2023).
  • It shows the number of live births per 1,000 population in a year.
• Sex Ratio at Birth (SRB):
  • For 2021-23, it was 917 girls per 1,000 boys.
  • Highest: Chhattisgarh (974)
  • Lowest: Uttarakhand (868)
• Mortality Indicators:
  • Crude Death Rate (CDR): 6.4 (2023)
  • Infant Mortality Rate (IMR): 25 (2023)
  • These indicators reflect the overall health conditions and quality of healthcare in the country.
