Part of the reason urban births are down is because teen births have plummeted. Also, U.S. black and Latino birthrates are now basically the same as white/Asian birthrates, but the steep decline in black/Latino is overrepresented in urban areas.

Also, birthrates have generally held steady in wealthy neighborhoods. Tribeca has one of the highest birthrates in NYC. So the story of urban birthrate decline is largely a story of black/Latino mothers having fewer children, especially at young ages.
