Summary
Kerala
Area of Science:
- Public Health
- Demography
- Vital Statistics
Background:
- Civil registration systems (CRS) in low- and middle-income countries offer insights into population health.
- Kerala, India, with over 33 million people, is a low-mortality context.
- This study assesses vital statistics in Kerala using a large dataset.
Purpose of the Study:
- To assess the accuracy and utility of vital statistics from Kerala's Civil Registration System (CRS).
- To compare mortality rates from the CRS with the Sample Registration System (SRS).
- To generate the first annual sex-specific life tables for an Indian state.
Main Methods:
- Utilized individual-level vital registration data from the Kerala MARANAM Study (2006–2017).
- Included over 2.8 million death records.
- Compared age-specific mortality rates between the CRS and SRS.
Main Results:
- No evidence of CRS underestimating mortality; CRS rates were smoother and less variable.
- CRS recorded higher death rates than SRS for low-mortality ages and women.
- Life expectancy in 2017: 77.9 years for women, 71.4 years for men.
Conclusions:
- Kerala's CRS appears reliable for mortality assessment.
- Findings support greater attention to and dissemination of mortality records in low- and middle-income countries.
- The study provides valuable data for public health and demographic research.

296
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

01:20Actuarial Approach
146
The actuarial approach, a statistical method originally developed for life insurance risk assessment, is widely used to calculate survival rates in clinical and population studies. This method accounts for participants lost to follow-up or those who die from causes unrelated to the study, ensuring a more accurate representation of survival probabilities.

01:22Life Tables
234
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...

477
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

335
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...
