“The nation’s overall mover rate increased from a record low of 11.6 percent in 2011 to 12.0 percent in 2012,” the U.S. Census Bureau has announced.

Roughly 36.1 million people who were one year and older moved in 2012, the statistics service said. The majority of those moves — 64.4 percent — were within the same county.

“The overall mover rate for the nation has increased since a record low. However, compared to previous years, mobility is still low for even our most mobile age group (18 to 29 year olds),” said Alison Fields, chief of the Census Bureau’s migration statistics branch, in a statement.

The moving peak in the U.S. was in the late-1940s through the 1950s, when more than 20 percent of the population moved each year.

The Census Bureau estimates that in 2011, Virginia and Pennsylvania gained the largest number of people from Maryland. The Free State gave up about 20,000 people to each of those states last year, the bureau concluded. And Washington, D.C. and Florida each gained more than 10,000 Marylanders.

But Maryland took on at least 18,000 Virginians, the largest number of new residents from any other state, last year. Among other origin states that provided large numbers of new residents to Maryland in 2011: Washington, D.C., Pennsylvania, California, New Jersey and New York.
