Census 2010 highlights
- Montgomery County's population reached 971,777 in 2010, an increase of nearly 100,000 people (11.3 percent) from 2000:
- Montgomery County is now the 42nd most populous county in the nation, up from 49th place in 2000. It remains the second largest jurisdiction in the Washington, D.C. metro area, next to Fairfax County, Virginia, with 1,081,726 residents.
- The top three population centers in Montgomery County are Bethesda (90,499), Germantown (86,395) and Silver Spring (71,452). Gaithersburg, Rockville, Wheaton and Aspen Hill each have populations of 50,000 or higher.
- Germantown had the largest population increase (19,955), followed by Rockville with 13,810 additional persons. Clarksburg, which had very few residents in 2000, grew at the fastest pace (480 percent); Aspen Hill was a distant second, increasing by 57 percent.
- Consistent with national and regional population trends, Montgomery County's population grew more diverse over the past decade:
- Montgomery County's Hispanic population grew at the fastest pace (64.4 percent), followed by Asian and Pacific Islanders (37.0 percent), Blacks (25 percent) and other minority groups (21.3 percent).
- The 39.3 percent increase in all minority groups combined offset a 7.8 percent decline in the number of non-Hispanic Whites living in Montgomery County.
- Most neighboring counties also had a decrease in non-Hispanic White population, including Fairfax County, Virginia, Howard County, Maryland, and Prince George's County, Maryland. In contrast, three inner-ring jurisdictions (Washington, D.C., Arlington County, Virginia and Alexandria, Virginia) gained non-Hispanic White residents.
- Nearly all neighboring counties saw increases in their minority populations. Only two counties lost minority residents: Washington, D.C. (-5.0 percent) and Arlington County, Virginia (-0.4 percent).
- Germantown added the most minority residents over the decade (26,839), with Hispanics, Asian and Pacific Islanders and Blacks accounting for roughly even shares of this increase.
- Minorities now account for more than half of the local population in 2010:
- Montgomery County is now one of 336 "majority-minority" counties in the United States.
- As of 2010, Non-Hispanic Whites make up 49.3 percent of the County's population, down from 59.5 percent in 2000.
- Hispanics are now the County's second largest population group (17.0 percent) followed by Blacks (16.6 percent), Asian and Pacific Islanders (13.9 percent) and Other (3.2 percent).
- All communities within Montgomery County saw an increase in the minority share of their population.
