It would only be fair to exempt millennials from the time-honoured societal expectation to leave the nest at 20 or so years old. Simply put, times have changed too much to expect millennials to follow the same trajectory through life that their parents took.

So it's not surprising to see that a significant proportion of millennials in countries all over the world are still living at home with their parents. A report by the Organization for Economic Cooperation and Development found that the number of youth living at home increased by 1.2% over the course of seven years (from 2007 to 2014). While a variety of factors have contributed to this, the report found that economic reasons were at the core of the issue.

Italy, Slovenia and Greece had the highest percentages of young adults living at home, with over 70% of them being between 15 and 19 years old. Such statistic isn't too surprising considering that these countries are 1) recently being hit with recession and 2) have a long-established tradition of staying at home longer than most Western cultures.

Canada, on the other hand, had the lowest percentage of young adults living at home (30%) among the other countries in the report. Denmark, Finland, Norway and Sweden also showed low percentages, ranging from 34% to 38%.

France showed the greatest increase (12%), which could be attributed to the fact that a staggering number young adults were unemployed in recent years (ex. 17% in 2015).

The percentages of other major countries are shown below:

  1. Italy - 80.6%
  2. Slovenia - 76.4%
  3. Greece - 76.3%
  4. Spain - 73.6%
  5. Czech Republic - 70.3%
  6. United States - 66.6%
  7. Chile - 60.7%
  8. Australia - 53.5%
  9. France - 53.5%
  10. United Kingdom - 52.4%
  11. Norway - 37.8%
  12. Finland - 36.9%
  13. Sweden - 35.1%
  14. Denmark - 34.3%
  15. Canada - 30.9%
