Older adults who are childless in the U.S. are more likely to be college educated, working and white than those with children. And their numbers are growing. A new Census Bureau report released Tuesday shows that 1 in 6 adults age 55 and older are childless. Childless older women appear to be better positioned than men when it comes to wealth and health. The study based on a 2018 survey was executed by the statistical agency to get a better understanding of childless adults since their numbers are growing due to declining marriage rates and an aging population.
