Multigenerational housing trends rise across the United States

Multigenerational living in the United States has seen a significant increase. According to 2020 U.S. Census Bureau data, the number of households consisting of three or more generations—such as a grandparent, adult child, and grandchild—has grown by nearly 1 million since 2010, reaching a total of 6 million households.

These multigenerational homes represent approximately 4.7% of all U.S. households and 7.2% of family households. While the Census Bureau defines these households by the presence of three or more generations, other organizations like Pew Research use a broader definition. Pew Research data from 2021 indicates that 18% of the U.S. population lives in multigenerational homes, a figure that measures individuals rather than households.

The trend is not uniform across the country. High concentrations of multigenerational living are found in states such as Hawaii (7.9%), California (6.0%), Texas (4.7%), Nevada (4.6%), New Jersey (4.5%), and Maryland (4.5%).
