The population peaked at more than two million residents in 1950; afterward the city's population declined while that of the neighboring suburban counties grew. Some residents moved out of the region altogether due to restructuring of industry and loss of tens of thousands of jobs in the city. Philadelphia lost five percent of its population in the 1950s, three percent in the 1960s and more than thirteen percent in the 1970s. Manufacturing and other major Philadelphia businesses, which had supported middle-class lives for the working class, were moving out of the area or shutting down in industrial restructuring, including major declines in railroads.
