These can directly impact the demographic, social, and economic characteristics of a place. For example, Detroit was a major global centre for car manufacturing in the early and mid 20th century and the investment from the TNCs gave the city a massive economic boost; a large number of well-paid jobs were created, which attracted thousands of internal and international migrants. However, after the 1950s, many of the manufacturing TNCs closed or relocated elsewhere with cheaper labour. This led to a massive population decline (1.8 million in 1950s but 700,000 in 2010), huge reductions of employment and increased social deprivation.
