Industrial suburbs and the growth of metropolitan Pittsburgh, 1870–1920

Abstract

In 1907, the Pittsburgh Survey team recognized that dispersed industrial development had created a metropolitan area stretching 30 to 50 miles from downtown Pittsburgh. Traditional interpretations of metropolitan formation fail to account for the crucial role of industry in this process. Beginning in the 1870s, the transformation from small, craft organized factories to integrated mills, mass production, and modern management organization in steel and other industries led many manufacturers to search for large sites with railroad and river accessibility. They purchased land, designed modern plants, and sometimes built towns for workers. Other firms bought into new communities begun as speculative industrial real estate ventures. Some owners removed their plants from the city's labour politics to exert greater control over workers. The region's rugged topography and dispersed natural resources of coal and gas accentuated this dispersal. The rapid growth of steel, glass, railroad equipment and coke industries resulted in both large mass-production plants and numerous smaller firms. As capital deepened and interdependence grew, participants multiplied, economies accrued, the division of labour increased, and localized production systems formed around these industries. Transportation, capital, labour markets, and the division of labour in production bound the scattered industrial plants and communities into a sprawling metropolitan district. By 1910 the Pittsburgh district was a complex urban landscape with a dominant central city, surrounded by proximate residential communities, mill towns, satellite cities, and hundreds of mining towns.
