63 extractive question-and-answer pairs built from SRS Abridged Life Tables 2015-2019, published by censusindia.gov.in. The source is a 68-page publication. Source-evidenced topics include abridged life tables, 2015-19, india, sample registration system, life expectancy, mortality, quinquennial age groups, states/union territories. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. Question types in the export: 38 factual, 17 list, 4 definition, 2 comparison, 2 summary. 25 of the 63 pairs (39.7%) ask explanatory questions; the remaining 38 are factual or table-based questions. 96.83% of rows pass the corpus quality gate.
This dataset contains 63 extractive question-and-answer pairs derived from the SRS Abridged Life Tables for 2015-2019, published by censusindia.gov.in.

| What do life tables 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 the SRS data, this office has been preparing life tables since 1970-75. | 266 | definition | 0.980 | https://censusindia.gov.in/nada/index.php/catalog/43473/download/47176/SRS-Abridged_Life_Tables_2015-2019.pdf | As we all know, a life table summarizes the mortality experience of a population during the period of study. | 2 | page=2,block=3 | 0.700 | valid |
| What does a life table summarize about a population? | the mortality experience of a population during the period of study | 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. | 252 | summary | 0.970 | https://censusindia.gov.in/nada/index.php/catalog/43473/download/47176/SRS-Abridged_Life_Tables_2015-2019.pdf | 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. | 6 | page=6,block=2 | 0.700 | |
| What is the primary 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 period 2015-19. 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 | summary | 0.970 | https://censusindia.gov.in/nada/index.php/catalog/43473/download/47176/SRS-Abridged_Life_Tables_2015-2019.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. | ||||

The female life expectancy at birth is higher than males in all the bigger States/UTs except Bihar and Jharkhand. The female life expectancy at birth is highest in the State of Kerala followed by NCT of Delhi and Himachal Pradesh, whereas it is the lowest for Uttar Pradesh preceded by Chhattisgarh and Assam in that order. Note: Data arranged in descending order of female life expectancy. | 643 | list | 0.820 | https://censusindia.gov.in/nada/index.php/catalog/43473/download/47176/SRS-Abridged_Life_Tables_2015-2019.pdf | The female life expectancy at birth is highest in the State of Kerala followed by NCT of Delhi and Himachal Pradesh, whereas it is the lowest for Uttar Pradesh preceded by Chhattisgarh and Assam in that order. | 18 |
