In recent years, many people in the United States have migrated to the west and south. What is the main reason?

1. The eastern United States and the Great Lakes region were the first regions to enter industrial civilization, where large-scale traditional industries such as steel, smelting and automobile manufacturing were concentrated. The industry is saturated for a long time, and the natural ecology is relatively poor. In addition, due to social reasons such as dense population and high unemployment rate, the cost of industrial upgrading in this area is high and cannot be easily realized.

2. The western and southern regions are vast, rich in resources and energy, and objectively have broad space for developing various emerging industries; In addition, the sudden emergence of Western Silicon Valley in 1980s, the epoch-making influence of IT industry in 1990s, the worldwide popularity of Hollywood and other industries and so on. It not only attracts a large number of local people, but also becomes the first choice for overseas immigrants to establish themselves in the United States.
