Sorta. If you're looking at Seattle, you might call Sumner an exurb. It's very far out, and past a lot of agriculture to get here. If you're looking at Tacoma, you might call it a suburb. Or not. It's not one of those towns built by white flight. It has been here for over 100 years, and hasn't grown a whole lot since the 1960's anyway. Half of the town acre-wise is still farmed (we grow sod for suburbanites! Ironic, huh?). My wife and I chose to move here because (1) the housing was affordable to us, and (2) the schools were good (if a bit white-bread).
