Is there a large population in America?

According to the report released by the US Census Bureau on February 6, 2002, the population of the United States is 28 1 10,000, which is still the third largest country in the world after China and India. The report is published on the internet in PDF format at http://www.census.gov/prod/2002ppubs/C2KBR01-1.pdf. The following is a press release issued by the US Census Bureau: (At the beginning of the press release) February 6, 2002 The US Census Bureau analyzed the situation in the United States with reference to the global situation and determined the development trend of the United States. The analysis report released by the Census Bureau of the Ministry of Commerce today shows that the population of the United States increased by 13% in the 1990s and continues to maintain its position as the third most populous country in the world. According to the 2000 census bulletin entitled "Looking at American population from a global perspective", the population of the United States in 2000 exceeded that of any country except China (65.438+0.3 billion) and India (65.438+0 billion). The total population of the world is 6 1 100 million. Peter Wei, director of the International Project Center of the Census Bureau, said: "The total population of a country can only reflect a very small aspect of its population situation. The population growth rate and age-sex structure of a country can explain the challenges facing this country, which are reflected in providing medical care for children and the elderly, educating teenagers, providing job opportunities for young people and welfare for the elderly. " The population below 15 in the United States accounts for 3% of the total population below 15 in the world, ranking fourth among all countries. The elderly population in the United States accounts for 8% of the total elderly population in the world, ranking third among all countries. This briefing pointed out the changes in the age structure in the United States and other developed countries. For example, in the late 1990s, the number of children under five years old in many developed countries declined. According to the report, in the next few decades, countries with low birth rates will face the problems of increasing the number of elderly people and decreasing the number of new workers. At present, the population of the United States accounts for less than 5% of the world population, but the growth rate of the United States in the 1990s is five times that of all other industrialized countries combined: 13% versus 2.5%. Other major countries in the world with more population growth in the 1990s: India, with a growth rate of19%; China, with a growth rate of11%; Nigeria, the growth rate is 33%; And Indonesia, with a growth rate of 19%. The population growth of these countries and the United States accounted for nearly half of the global population growth in the 1990s. According to this analysis, the population growth rate of the United States exceeds that of all other developed countries, because most of the birth rates in other industrialized countries have declined, and a large number of people have immigrated to the United States. Other main messages in the report are:-Although the total population of the United States accounts for only about a quarter of the total population of India, there are more people over 80 in the United States than in India. The population of the United States is more than twice that of Nigeria, but there are fewer children under five in the United States than in Nigeria. In the next 25 years, the world population is expected to increase by 29%, almost all of which are in developing countries. It is estimated that the population of the United States will increase by 23% by 2025. By 2025, the world population over 65 will nearly double, while the number of children will only increase by 3%. The elderly population in the United States is expected to soar by nearly 80%, and the number of working-age adults and children will increase by 15%. This bulletin is one of a series of reports on the analysis of population and housing data collected in the 2000 census. It includes data from the international database of the Census Bureau, covering 227 countries with a population of over 5,000.
