The AEIA report highlights the decline in marriage rates among disadvantaged children that began 30 years ago and ended in 2022. The report suggests that this decline was caused by the rise in single-parent families and the increasing number of non-marital births. The report also notes that the decline in marriage rates has led to a decrease in the number of children living with married parents. The report uses data from the Census Bureau to show that the number of children living with married parents has decreased by 15% since 2000. The report suggests that this decline in marriage rates is a result of the COVID-19 pandemic, which has caused a significant increase in the number of children living with single parents.
