The Industrial Revolution urbanized the world and automated the production of food and goods during the 17th and 18th centuries. During this period factories were built that rivaled small town mills and manufacturing facilities. These factories were huge manufacturing centers that centralized food production. People migrated from rural areas to these manufacturing centers to find employment, and in doing so they urbanized areas that grew into large cities. Industrialization in New York City caused its population to grow from 33,000 to 300,000 from 1790 to 1840.
