As reported in the Washington Examiner,  an updated analysis by local governments shows that up to 1.7 million new residents are expected to flood the D.C. region within the next three decades.  As describes,

The draft forecast from the Metropolitan Washington Council of Governments calls for the area’s population to climb to 6.9 million by 2040, about 131,000 residents more than the group previously estimated.

While much of the growth is anticipated to be in the Virginia suburbs, Maryland will also have its share.  As noted,

. . .the immediate Maryland suburbs — Montgomery and Prince George’s counties, Gaithersburg and Rockville — are [also] poised to add plenty of heft to the region’s population. The study found that those four jurisdictions will grow by about 420,000 people.

The study, which also includes projections for job growth, will be used in discussions over transportation funding and other infrastructure and development policies in the State.  For more information, see the complete article.
