| What does a life table give about a cohort as it diminishes by deaths? | the probabilities of death and survival at various age groups. | Introduction The life table is a mathematical table which gives the life history of a hypothetical group or cohort as it is gradually diminished by deaths. It gives the probabilities of death and survival at various age groups. A life table summarizes the mortality experience of a population during the period of study and provides concise measures of the longevity of that population. In the words of William Farr, life table is the ‘Biometer’ of the population. The data for construction of life tables considers both deaths and the population exposed to risk of death classified by age. 2. life expectancy at various broad age groups has been estimated through Sample Registration System (SRS) since 1970-75. | 165 | definition | 1.000 | https://censusindia.gov.in/nada/index.php/catalog/42517/download/46143/SRS-Abridged_Life_Tables_2014-2018.pdf | It gives the probabilities of death and survival at various age groups.

| What is the objective of the Sample Registration System? | providing reliable estimates of fertility and mortality indicators at State and National levels for rural and urban areas separately | The Sample Registration System (SRS) is a large- scale demographic sample survey based on the mechanism of a dual record system with the objective of providing reliable estimates of fertility and mortality indicators at State and National levels for rural and urban areas separately. The estimated age-specific death rates derived from the SRS provide the necessary database for undertaking construction of abridged life tables. To adjust for the sampling fluctuation and for augmenting the sample size, five-year average is compiled for estimating age-specific death rates separately for rural and urban areas, both for male and female. 3. The present report covers the life tables for the periods 2014-18. The life table has been constructed for all India and bigger States/Union Territories (having population 10 million and more) along with Himachal Pradesh. | 150 | definition | 1.000 | https://censusindia.gov.in/nada/index.php/catalog/42517/download/46143/SRS-Abridged_Life_Tables_2014-2018.pdf | The Sample Registration System (SRS) is a large- scale demographic sample survey based on the mechanism of a dual record system with the objective of providing reliable estimates of fertility and mortality indicators at State and National levels for rural and urban areas separately. |
| What does a life table summarize? | the mortality experience of a population during the period of study | The Sample Registration System (SRS) of the Office of Registrar General & Census Commissioner, India brings out Abridged Life Tables annually. The report presents the life tables for India and bigger States/Union Territories. As we all know, a life table summarizes the mortality experience of a population during the period of study. It states the probabilities of death and survival of a hypothetical group or cohort at different ages, which gradually diminishes due to deaths. The life tables brought out under SRS present the scenario of life expectancy at birth and at various quinquennial age groups. 2. Based on SRS data, life tables have been prepared for the periods 1970-75, 1976-80, 1981-85 and 1986-90 at five yearly intervals. Since the 1986-90 issue, life tables have been brought out annually on a five yearly moving average basis so as to form a continuous series. | 266 | definition | 0.980 | https://censusindia.gov.in/nada/index.php/catalog/42517/download/46143/SRS-Abridged_Life_Tables_2014-2018.pdf | As we all know, a life table summarizes the mortality experience of a population during the period of study. | 3 |

| What do the life table estimates of Jammu & Kashmir represent? | the erstwhile state of Jammu & Kashmir, as was during the reference period from 2014 to 2018 | The life table estimates of ‘Jammu & Kashmir’ represent the erstwhile state of Jammu & Kashmir, as was during the reference period from 2014 to 2018 of the present report; and therefore include the present-day Union Territories of Jammu & Kashmir and Ladakh. For the case where, for a given age-group and sex, no deaths were reported in the sample of 2014-18, the mortality rate has been imputed on the basis of a geographic approach, to generate the life tables. for females in the rural region of NCT of Delhi and for males in the urban region of Kerala, the mortality rate in the age-group of 5-9 years for females in the total region of NCT of Delhi and males in the total region of Kerala, has been used as the imputed mortality rate respectively. 4. | 56 | summary | 0.970 | https://censusindia.gov.in/nada/index.php/catalog/42517/download/46143/SRS-Abridged_Life_Tables_2014-2018.pdf | The life table estimates of ‘Jammu & Kashmir’ represent the erstwhile state of Jammu & Kashmir, as was during the reference period from 2014 to 2018 of the present report; and therefore include the present-day Union Territories of Jammu & Kashmir and Ladakh. |
