According to report by researchers on Friday, over half of young adult Americans live with their parents, between February and May.
Report said, 18-29 year-old living with at least one parent rose from 47 per cent to 52 per cent and stayed at that level through July, as an unprecedented proportion that is doubtless linked to the coronavirus but also reflects a deeper trend.
This data analysts released by Pew Research Center, means about 26.6 million young adults in American have their parents for roommates.
The study is based on data gathered by the US Labor Department during its monthly survey of a representative sample of 60,000 people.
The rise was most marked among 18-24 year-olds, with 71 per cent of them living with their parents in July, up from 63 per cent in February.
However, among the ethnic groups, breakdown showed that the trend was strongest inside the Hispanic community, with 58 per cent of adults aged between 18 and 29 living with their father, mother or both.
The increase was caused and pushed by the coronavirus pandemic as young adults struggled to get by, it is part of a longer pattern.
Pew says, despite more than 10 years of economic growth before the Covid-19 outbreak hit the United States, the number of young adults living outside their family circle had diminished in recent years.
The 47 percent already living with their parents before the pandemic represented the highest rate since the Great Depression in the 1930s, although the figures were collected less frequently then.
In the 1960s, 70s and 80s the proportion of young adults living with parents fell to below 35 percent.
