Summed from the same decennial Census race tables behind the Birth & Mortality Trends page's population-share panel — white plus every non-white category reported that year. 1900 has no computable total here for the same reason that page's share panel excludes it: that year's table has no white count in the same source to sum against.

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.
