The latest data released by the Census Bureau shows more people are moving to the District than almost any other place in the United States.
During the last two years, more than 30,000 new residents have relocated to D.C, which is a big number when compared it to the rest of the country. North Dakota was the only state that grew faster than the District.
Census officials say the District's population now stands at just more than 632,000 people.
Rhode Island and Vermont were the two states that lost population growth over the past year.
Other states that topped the list as fastest growing were Texas, Wyoming and Utah.
