In the Boston Globe 's Ideas section, I examine the Hub's population resurgance and the reasons behind it, including new housing and immigration:
In 2013, Boston is a denser city than in decades, and its gravitational pull only seems to be increasing. According to figures released last month, the city is now growing faster than its suburbs—and, in fact, faster than any urban area northeast of New Jersey. Over a two-year span culminating in July 2012, Boston grew 3.1 percent from the official 2010 count, the Census Bureau estimates, to 636,479 people.
