A real, honest gap sits between the chart above and this number: no continuous
total-population series exists in this data for 1960–2023. The
Birth & Mortality Trends
page's 1970–2007 panel has birth and death
rates for that span, not a population
count — a total could be back-calculated from a rate, but that's an estimate wearing a
reported figure's clothes, and this site doesn't present one as the other.
