Three of the top four reasons people are having fewer children than they'd like to are economic, according to a survey released by The New York Times on Thursday.

"Child care is too expensive" was the top reason (64 percent), the Times found, with "worried about the economy" at No. 3 (49 percent) and "can't afford more children" (44 percent) coming in fourth, showing that economic insecurities and financial concerns are causing many young Americans to skip or delay having kids.
