D.C. leapfrogs over Baltimore for population, Census says

WASHINGTON — The Washington metropolitan area continues to grow, adding 63,793 residents in the past year, according to the latest Census estimate.

The growth came mostly in the District of Columbia, Loudoun County and Montgomery County, which accounted for more than half of the region’s growth.

The District saw 12,392 residents move in, continuing a trend that has seen the city’s population climb by 70,461 since the 2010 census.

D.C. has leapfrogged nearby Baltimore, which has only seen a subtle change since the census. Baltimore had 20,000 more residents in 2010, but D.C. now has 50,000 more residents, according to the newest estimate.

Loudoun County was fastest-growing jurisdiction in the region and the 32nd fastest-growing county in the nation, adding 12,135 residents in the past year, a 3.3 percent increase. D.C. barely edged out Loudoun County year-over-year in total new residents.

Fairfax County continues to be the largest jurisdiction in the D.C. metro area, with 1.1 million residents.  Montgomery County is second, with slightly more than a million residents. Prince George’s is third, with more than 900,000 residents, adding 6,178 people in the previous year.

Despite the growth in the region, a lot of people are leaving.

The region lost 28,000 residents to other cities in the nation, but that loss was countered by more than 46,000 additional births than deaths and nearly 47,500 international migrants.

The only jurisdictions with significant numbers of people moving in from other parts of the country or region in the past year were Loudoun and D.C.

Fairfax, Montgomery and Prince George’s counties all saw thousands of residents move to other counties.

The only jurisdictions to lose residents in the area were Fredericksburg and Manassas Park, which each saw a slight net loss.

Despite the year-over-year loss, Fredericksburg is the 22nd fastest-growing county or county-equivalent in the nation since the last census.  It ranks second in the region.

In gains since the last census, Loudoun County tops the local jurisdictions and is the 15th fastest-growing area in the nation.  In the top 100 counties nationally for fastest-growing communities, Falls Church is 50th, Prince William County is 64th and the District is 76th.
