from the wrong side of the tracks

If someone comes from the wrong side of the tracks, they come from a poor or unfashionable area of town. I know kids back home who come from the wrong side of the tracks. When they go to school, they haven't eaten and their clothes are all torn. Note: Railway tracks sometimes mark boundaries between different parts of a town, for example between richer and poorer areas.
