With the industrial revolution beginning in England in the 19th century, many areas that formally based the economy on an agricultural basis became exporters of a cheap labor force.

One example of this is Manchester distribution of space, which was brought on by a boom in textile manufacture during this Industrial Revolution, previously it could be hardly imagined that such an area was to become a big amount of land to be center of so many factories with the consequent construction of the housing buildings. Manchester became a city as a consequence of urbanization.
