Much has been written about the population changes revealed in the 2010 Census, focusing largely on the surging population in the Sun Belt region. However, now that the 2010 data on the foreign-born population also is available, a surprising pattern of change has appeared in the region of the nation’s capital.

Among the states that saw the largest increases in their foreign-born share between 2000 and 2010, Maryland had the largest jump in the country – increasing from 9.8 percent to 13.9 percent of the state’s total population. Virginia was not far behind with the third highest foreign-born share increase – from 8.1 percent to 11.4 percent. Maryland’s neighbor, and another non-sunbelt state, Pennsylvania had the fourth largest jump in its share of foreign-born population – from 4.1 percent to 7.4 percent.

These were not the nation’s highest foreign-born shares, but these states obviously are catching up with the most immigrant-impacted states.
