Why Washington D.C. is so large: Census data
741,977 people moved from the state of Washington to the state’s capitol in 2017.
That’s more than all the residents of the city of Baltimore, the state capital, moved during the same period.
(The Census Bureau defines capitol as the city’s central business district.)
The capitol is not the only city with large populations moving.
Between January and March of this year, the population of Los Angeles, California, moved nearly a million people to the nation’s largest city.
In New York City, about 8 million people moved.
And in Seattle, Seattle’s population doubled between January and April, from 634,000 to 683,000 people.
The state capitol has a population of about 1.7 million, but the population in the city is roughly half that.
There are only about 1 million people in the state cap.
