What are the reasons for the migration of American population from the northeast to the west and south in recent decades?

1. Most of these areas are emerging high-tech zones with less pollution, better urban environment and better employment conditions.

2. Most of the migrants are elderly people, seeking a comfortable living environment, and the south has a subtropical monsoon humid climate.

First, the densely populated northeastern United States has entered the late stage of urbanization, and urban diseases such as industrial pollution, crowded population and deterioration of living environment are plaguing people's lives.

Second, the western part of the United States is located in temperate maritime climate zone and Mediterranean climate zone, and the southern part is located in subtropical climate zone. Superior climatic conditions have become the pursuit of many people in the United States. The development of oil and gas resources in the south and the development of science and technology in the west have promoted the construction of infrastructure and the improvement of social security system. Therefore, in recent years, many people in the United States have migrated to the west and south.

Third, 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, the natural ecology is relatively poor, the population is relatively dense and the unemployment rate is relatively high.

Fourth, 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.
