Female population at risk: 4 607 238 284 in 1975–2019; 76 552 203 in 1975; and 126 466 141 in 2019. Male population at risk: 4 349 115 179 in 1975–2019; 70 575 827 in 1975; and 121 029 013 in 2019. Standardization was based on the women’s and men’s age distribution of the annual mid-year US population.
