While almost every industry has returned to pre-pandemic levels, child care is still short 60,000 teachers as of last month. Nearly 16,000 centers and home-based day cares closed between December 2019 and March 2021, according to a report by Child Care Aware, a leading child care advocacy organization. That amounts to a drop in the supply of child care of 9 percent overall and 10 percent for family child care homes, a more affordable option for many families.
