Who told me about the demographic composition of the United States?

As of March 20 14, the population of the United States was 31780,000, making it the third most populous country in the world. This is the latest figure of the total population of the United States in 20 14 years given by the US Census Bureau and the World Bank.

The American population is highly urbanized. In 2008, about 82% of the population lived in cities and their suburbs (the world urbanization rate was 50.5% in the same period), which made many vast areas of the United States uninhabited. California and Texas are the two most populous States, and the population center of the United States continues to tilt southwest. New york City is the most populous city in the United States.

America is a traditional immigrant country. The latest reports "Changes in Global Migration and Remittance Patterns" released by the Pew Research Center in the United States in February 20 13 and 17 show that from 1990 to 20 13, the number of immigrants living in the United States doubled in 20 years, reaching 46 million, far ahead of other countries. Even excluding illegal immigrants, since 200 1, about 884,000 foreigners immigrated to the United States every year, and a new immigrant set foot on American territory every 26 seconds. Among the developed countries, the United States is the only major economy in the world whose population is still growing or even growing rapidly. In addition to the good fertility rate, the increasing number of immigrants has also contributed. American immigration policy attracts talents and elites from all over the world. In China, for example, more than 70% Chinese Americans have bachelor degree or above, and their occupations cover scientists, researchers, senior engineers and doctors. According to the U.S. Census Bureau, the number of China immigrants (including those born in Chinese mainland, Hong Kong, Macao and Taiwan) living in the United States in 201/kloc-0 was 223 1 000, accounting for 5.5% of the total number of immigrants, making it the largest Asian group in the United States. China has become the second largest source of overseas immigrants in the United States after Mexico.

According to the Blue Book of International Talents: Report on International Migration in China published by China and Globalization Think Tank and China Academy of Social Sciences, in 20 12, the number of China citizens from Chinese mainland who obtained permanent residence visas in the United States was 8 1784, accounting for 7.9% of the total number of permanent residence visas in the United States. Among them, investment immigration green cards accounted for 80. 1% of the total issued in the United States that year.

Analysis of American population situation

The United States is the only developed country in the world whose population is still growing at a high speed, which makes the United States maintain the momentum of high-speed growth in production and consumption for a long time, and makes the quantity of American national strength show a continuous development and upward trend. However, while the population of the United States is growing rapidly, the demographic structure of the United States is also undergoing fundamental changes. As the main force of population growth, a large number of Latin American immigrants and their descendants have a low level of education and English, which makes the overall quality of the American population show a long-term downward trend. The decline of population quality and quality will inevitably affect the global competitiveness of American products and services, and fundamentally lead to the decline of American strength, international status and influence in the first half of the 2/kloc-0 century and beyond.

American population distribution map

According to statistics, the total fertility rate of American women is 2. 1, and the total population in 20 10 has reached 308 million, ranking third in the world. The United States began to enter an aging society as early as the 1940s, and now the population over 65 accounts for 17.4% of the total population, which is a typical aging society.
