Industrialization, Cities, and Class Structure

Before industrialization, most people lived on farms because farming needed lots of hands. Two changes broke that pattern at once. Factories offered steady wages, often better than farm labor paid, pulling workers toward cities. At the same time, agricultural mechanization, things like seed drills and mechanical reapers, let fewer farmhands work the same land, pushing workers off it. A pull and a push moving the same direction meant migration wasn't just appealing, it became necessary for people who no longer had farm jobs waiting. This rural-to-urban shift is also tied to population growth: better food supply and, later, better sanitation let more people survive, so the population curve bent upward right as cities filled up.

Britain shows this clearest. In 1800, most of the population was rural, scattered across farms and villages. Factory towns like Manchester and Birmingham grew fast through the early 1800s as textile mills and ironworks multiplied. By around 1851, Britain's census showed urban population had overtaken rural population for the first time, a crossover no country had hit before. That line kept climbing through the century as more migrants arrived looking for factory work.

Concentrating workers in cities did more than move bodies. Before industrialization, society was mostly landowners and scattered peasants, who had little ability to coordinate. Factory work packed thousands of laborers into the same neighborhoods, under the same harsh conditions, which gave them something peasants lacked: the physical closeness to organize. Out of this came a new urban industrial working class, forming labor unions and pushing for political rights, a class structure shift that connects directly to the stages of development and core-periphery patterns explored next.
