The proportion of U.S. adults who don't have children and say they're unlikely to want them in the future is growing, according to a new Pew Research Center survey published Friday.

The big picture: The survey found that about 44% of non-parents aged 18-49 said it was "not too or not at all likely" that they will have children.
This represents a 7 point increase from 2018, when 37% of respondents said the same, per Pew Research Center.
Adults below 50 with children who say they're unlikely to have any more — about 74% — remain consistent with 2018 levels.
Between the lines: About 56% of non-parents who say they're unlikely to have kids say it's because they "just don't want" them.
Among other reasons, 19% cited medical issues, 17% cited finances and 15% said because they don't have a partner.
9% based their decision on the "state of the world" and 5% of these respondents attributed their reluctance to climate change.
