- Birth chances are weighted by annual births rather than population; the site says its model covers 186 countries and territories.
Field notes
The homepage describes assigning a family as well as a country, with circumstances such as household income, parents’ work, and urban or rural setting tied to country data. Players make choices as the years advance, and the site says outcomes are presented with a survival curve and a year-by-year colored timeline rather than a score. It also cautions that characters and stories are fictional and that an individual run is not a prediction.
