I still find this to be relatively large. As explained by Axios:
What’s happening: The percentage of young adults — or “boomerang kids” — who live with their parents is back to pre-pandemic levels, according to a recent report from the Federal Reserve Bank of Cleveland, Nathan writes.
By the numbers: 46.61% of adults aged 18–29 were living with their parents as of September, the lowest point since February 2020. The big picture: 36% of boomerang kids live with families in the top 10%, with a household income of more than $140,000.
