||This map shows where industrial centers were developing in Europe in the mid-1800s. It also shows varying degrees of urbanization. Notice that Britain, which industrialized first, already has at least 20 percent of its population living in cities of 100,000 or more. The regions on the continent with between 6 and 10 percent of the population in such large cities are also the regions that experienced greater industrial development. Industrialization and urbanization went hand in hand.
