Between April 2010 and July 2012 D.C. continued its steady growth rate, adding 30,600 residents to bring the city’s total population to 632,323—higher than Wyoming and Vermont, and could even put us above Baltimore for the first time in history. (Baltimore’s population numbers will be released next year.)

From July 2011 to July 2012, D.C. added 1,109 residents per month, topping the 1,085 new residents per month the District experienced in the 15 months prior. The growth is fueled by migrations from other states—8,953 from July 2011-July 2012—and a baby boom totaling 9,000 kids a year since 2008. (We recently reported that wards 1 and 2 are producing the most kids in the whole city.)

Though the comparison shouldn’t be made, the Census now puts D.C. as the fastest-growing state in the country, followed by North Dakota, Texas and Utah. (Last time a count was released, D.C. was not the fastest-growing city.) Though were still a ways off, North Dakota is the next target: with 699,628 residents, it’s not impossible to think that D.C. couldn’t surpass it over the next decade or so. Don’t forget that the city boasted over 800,000 residents in 1950 and in the mid-700,000’s in the two decades after, starting a swift decline in the 1980s.

As Greater Greater Washington notes, we can now sadly say that there are six members of Congress that represent states with fewer people than D.C.
