Western cities such as Pittsburgh, Cincinnati and New Orleans in the US grow rapidly due to the fact that citizens of the country are drawn to them. People migrate to the cities in search of work, and this demand leads to more houses and apartments being built. As the population grows, businesses and shops increase in number as the needs of the people must be met. Again this leads to employment opportunities, and somewhat of a multiplier effect is produced, leading to cities growing at a fast pace. Urban areas are set to grow by around two per cent this year in America, and the population of major cities is expected to double in the next four decades.
