As of July, over half of adults under 30, 52%, are now living with one or both parents. The previous recorded high was 48% in 1940, eight decades ago. No data is available for the period including the Great Depression, but it’s likely the number was higher during that period. The majority of this increase comes from those in the 18 to 24 age range, with particularly large spike in April.
In some instances this could be a conscious choice, at least initially, as people moved in with their parents during lockdowns so they could isolate with family members instead of alone while working from home. Even for those for whom this was the plan, their stay has been extended longer than expected. For most people, though, it’s because they aren’t working from anywhere — it correlates strongly with rising unemployment numbers. Unemployed young adults aren’t financially stable enough to become independent homeowners. Increasing student loan debt is also a significant factor.
