Why did people create cities and a civilization?

Urbanisation happended in the 1900s onwards in MEDCs like the USA and UK. It started with the Industrial Revolution, where factories attracted a lot of workers to move nearby. These workers required houses and services (schoold, doctors, shops) and so urban settlements began to grow. As people became wealthier adn more mobile they started to move to the suburbs (suburbanisation) and eventually to the rural urban fringe (counter urbanisation).

However, urbanisation is still occurring in LEDCs like Brazil and India. This is due to massive rural to urban migration, where people move to the cities to escape the serious rural poverty that exists in countryside areas. This has lead to a huge increase in urban populations in LEDCs and has lead to the development of shanty towns in such areas.
