About a third of Bostonians are between the ages of 20 and 34. The city is home to the largest percentage of millennials in the country.

“What we need to really do is have an effort to build housing for this particular population in the same way that we went ahead and built that housing for the new working families coming to Boston a century ago,” said Barry Bluestone, a housing economist at Northeastern University.

His argument is that the city does not need new housing for families. It already exists in the form of triple-deckers. The problem, Bluestone says, is that these days, young folks are teaming up with friends to rent triple-deckers and essentially pricing out families.

So he says the city should build new housing just for millennials.
