If “Inside the Beltway” were a city, how would it compare to other major cities? It would be
almost the size of Los Angeles but half as dense
a little larger in area than Chicago but less dense than Los Angeles.
The latest Census data show that Montgomery County reached 1 million people, a statistic that has gotten a lot of worthy attention. Still, let’s remember that jurisdiction boundaries are pretty arbitrary. As commenter AlanF also pointed out, DC, Arlington, and Alexandria (the “core jurisdictions”) have just about reached 1 million as well (999,662 as of the latest Census estimates).
Michael Rodriguez decided to analyze “inside the Beltway” as if it were its own city. Given the way the Beltway separates communities, it’s a good natural boundary and means more than the artificial lines between counties or between DC and Maryland.
Inside-the-Beltway would have about 1.7 million people.
in 423 square miles. That’s a little smaller than Los Angeles and only about half the density of people per square mile.
Update: Commenter npm points out that Rodriguez’s table appears to be incorrect, and “Inside the Beltway’s” density may be more like 80% of Los Angeles’ rather than 50%.
Update 2: A reader with access to GIS systems has estimated the land and water area of “Inside the Beltway.” Plugging in those numbers, and assuming that the other numbers on the table are correct, the table would look like this.
Update 3: Rodriguez has updated his post and fixed the errors in the DC and “Inside the Beltway” numbers. I’ve updated the table to reflect them.
|Inside DC Beltway||266||10||256||1,725,686||6,749|
|District of Columbia||68||7||61||632,323||10,298|
|New York City||469||166||302||8,336,697||27,541|
The lower density than Los Angeles comes because most of the land inside the Beltway is actually not very dense, except for central DC, Capitol Hill, along Georgia Avenue, the Rosslyn-Ballston corridor, bits of Silver Spring and College Park, and a few other places.
Also, if “inside the Beltway” were a city, metonymy in the national press would be even more severe than it is today.
