| The source lists as "agglomerations," which is a pretty nebulous term. Washington most definitely is not one of the largest cities-- it's only got a half million people-- and Baltimorans would probably not accept that they count as part of DC. That said, the source also doesn't count surrounding cities in Toronto, for instance. If the same area surrounding DC were overlaid on the Golden Horseshoe (Toronto, Mississauga, Hamilton, etc) Toronto's population would be around 8-9 mil. |
