I came across this quiz on Sporcle that shows pretty clearly the shift from innermost suburbs like Hamtramck to inner ring suburbs like Roseville and Warren to outermost sprawlers like Troy and Shelby. A bit surprised none of the Grosse Points show up, but they are pretty small individually. Also, look at the size of number ten explode from 1950 [[20,549) to 1970 [[70,020).
