The total fertility rate (TFR) is the number of children a woman would have over her life if she experienced this year's birth rates at every age. A TFR of about 2.1 keeps a population the same size from one generation to the next, before migration. Values from 1960 are World Bank estimates; earlier values are reconstructions from the Human Fertility Database, UN estimates for 1950–59, and Gapminder's modelled series further back. The newest years use provisional national statistics where they line up with the World Bank series, and show them separately where they don't. Methodology
