Who moves, and who stays put? A new study by the Pew Research Center takes a close look. The study finds that fewer Americans are moving now than previously. Some 13 percent of Americans moved from 2006 to 2007, down from a high of 21 percent in 1951; the Census predicts a further decline to 11.9 percent by 2009. That said, America remains a highly mobile society. Almost two-thirds (63 percent) of adults said they have moved to a new community at least once in their lives; 15 percent say they have lived in four or more states.

Highly educated people are much more likely to be mobile: more than three-quarters (77 percent) of college graduates have moved at least once compared to 56 percent of those with a high school diploma. Younger Americans, unmarried people, and those who are foreign-born are among the most likely to move. The Midwest is the most rooted region; the West the most mobile. The main reasons stayers stay: family ties, a desire to stay in their home town.

According to the New York Times, it takes a while for all those new young people to find their fit in the Big Apple.

But for many, the thrill of arrival is often tempered by the sinking realization of what an alienating place the city can be, especially for those who are not wealthy or who do not have a pre-existing network of friends. Nothing comes easily, even if one can get past the dauntingly high cost of living. The subway maze seems indecipherable. People are everywhere, but ignore each other on the street. Friends might live in distant neighborhoods, and seeing them often requires booking time, like an appointment, weeks in advance.
