How does the metro quiz work?
Type a city, town or community and press Enter. If it is in the quiz, its real boundary fills in green on a blank street map that has highways, parks and water but no place names. A name shared by several places, like Springfield, fills in all of them at once. Hover a found city to see its population, land area and density, ranked within its state. Only places inside the metro’s counties count.
