Field notes
The page breaks each draw into country, sex, urban or rural setting, income quintile, and birth year, then describes choices in school, work, residence, and health. Its sample output includes specific events and a cause of death, and is said to be generated from a seed and a life table. The data sections also cover life expectancy by country and sex from 1950 to 2023, alongside child mortality and population changes.
