How did the industrial revolution affect different classes up to 1850?

During the early 19th century, there was a large population growth caused by the improvements of the Agricultural Revolution of the 18th century. Many historians believe this population increase was due to a dramatic decline in the death rate. A drop in famines, warfare and illnesses, and an increase in food sources, all mixed to cause a population spike. As early as 1850, many European cities were centers of industrial growth. In fact, by 1850, over 50% of the entire population of Great Britain lived in either a town or a city instead of in a rural community.

The growth of cities led to horrible living conditions. The wealthy fared far better than the industrial workers because they could afford to live in the suburbs on the outskirts of the city. However, for most of the factory workers, cities were dirty, crowded places where epidemics frequently broke out.
