Sources and model limitations

The game dataset contains 172 countries and territories. It was inherited from the MIT licensed born-somewhere repository. Per-record statistical years and primary-source provenance were not supplied; we do not present these weights as verified current statistics.

Birth mode divides each annual birth weight by the sum across covered countries (131,932,758). Population mode separately divides each population weight by the covered total (8,078,638 dataset units, apparently thousands). Coverage and rounding affect both results.

Life expectancy, education and income fields are inherited estimates. Events, careers, relationships and mortality are simplified fictional game mechanisms, not validated forecasts or medical advice. Missing values must not be interpreted as zero.

Primary resources for future calibration: UN World Population Prospects, World Bank crude birth rate, World Bank life expectancy. Linking these resources does not mean the bundled data has been checked against them.
