How many babies are born in the United States each year?

How to get close to this number

Use the same population-over-lifespan method, scaled to one country. A few hundred million people divided by a lifespan of roughly eighty years gives an annual replacement figure in the millions, and the explanation converts that to about ten thousand a day. Doing the arithmetic from the population is far more reliable than reaching for a remembered statistic.

The trend is the part people get wrong. Births peaked in this country nearly two decades ago and have declined in most years since, so anyone extrapolating upward from an older impression will overshoot. Falling births are now the norm across wealthy countries, and the explanation names the consequence directly: population growth depends on migration rather than on natural increase.

Be careful to separate the three numbers that get confused here. Total births is a count; the fertility rate is births per woman; and the general fertility rate is births per thousand women of childbearing age. All three can move in different directions at once, because the number of women of childbearing age is itself changing. A headline about "record low fertility" is usually about one of the rates, not about this count.
