United States, 2013–2023: first, second and later birth rates all fell
Per woman at that period's rates: first births 0.73 → 0.64, second 0.59 → 0.51, third and later 0.54 → 0.47; total 1.85 → 1.62. First children now come later (at 27.9 instead of 26.7). These series cannot separate postponement from births that will never occur.
