A Statistics Canada report is digging deeper into what kind of adults live with their parents at a time when more are doing so than ever before.

Close to 1.9 million Canadians aged 25 to 64 lived with at least one parent in 2017, according to a Friday release. That's more than double the number in 1995.

Then, Canadians at home made up only five per cent of the adult population aged 25 to 64; now it's up to nine.

Close to three-quarters of them have never lived apart from their parents.

"This finding held true regardless of age group," reads the report, adding that 60 per cent of those aged 55 to 64 and living with a parent had always done so.

Seventy per cent reported being single, meaning they were unmarried and had no common-law partners.

But they're not just melting into the couch. While students made up a significant share of adults living with parents, most had paid employment: 74 per cent, only slightly fewer than the 80 per cent of those not living with parents.

They were less likely to have worked full-time permanent jobs in the prior year, though: 72 per cent had worked 41 to 52 weeks compared to 82 per cent of those living apart from their parents.

Culture also has a role to play. Twenty-one per cent of people identifying themselves as South Asian (including people of Indian, Pakistani and Sri Lankan descent) and 19 per cent of people of Chinese descent aged 25 to 64 lived with parents, more than double the nine per cent of the total Canadian population.

Statistics Canada said these groups "may have cultures which value intergenerational living arrangements."

The 2016 census noted that multi-generational living arrangements were common among immigrant populations.

The agency said further analysis of these demographics could reveal what motivates Canadians to live with their parents.
