What is the approximate population of the United States now?

At 7: 46 am EDT (10 10/7), the total population of the United States exceeded 300 million, which is a milestone in the history of American population. The United States increases every 1 1 second 1 person. According to the data of the US Census Bureau, in the United States, 1 person is born every 7 seconds, 1 person dies every 13 seconds, and 1 immigrant arrives in the United States every 3 1 second. Considering these factors, the net population growth rate is per 1 1 sec 1 person. Therefore, according to this growth rate, the 300 millionth person in the United States will be born at 7: 46 am EDT in June 17. It took 52 years for the American population to grow from 1 100 million to 200 million, but it only took 39 years to grow from 200 million to 300 million. It is estimated that it may only take 37 years to increase 1 100 million. In the past 100 years, the population growth rate of the United States was the fastest in its history, especially in the "baby boom" period after World War II. After entering the new century, the population is still rising steadily and is expected to reach a stable period in 2070. At present, the total population of the world is about 6.5 billion, and the population of the United States ranks third in the world after China and India. The rapid growth of new immigrants is accompanied by the growth of population, and some changes have taken place in the population structure and distribution of the United States. A remarkable change lies in the racial composition of the American population and the role played by immigrants. In the 1970s, new immigrants only accounted for 5% of the total population of the United States, and now this number has risen to 12. 1%, and it is still rising. Different people have given different explanations for this new situation. William Frey, a population expert at the Brookings Institution, a Washington think tank, said: "Immigration has brought us diversity and introduced new ideas, skills and cultures, which means that we can do business with people from other countries better." Roy Roy baker, president of Digital America, an organization that specializes in immigration issues, believes that the consequences of this situation are traffic jams, more constraints, loss of individualism and reduction of freedom and space. In a word, America is more and more like Europe. In addition, Baker blamed all the reasons for the long-term population growth on immigrants. He said: "If the growth of the immigrant population is zero, we will never reach 300 million people. We should only have 245 million today. " At the same time, the population of the United States is still unevenly distributed. More than half of Americans live in 1 1 in 50 states in the United States, mostly in coastal areas. The areas with rapid population growth are located in the south and west of the United States. However, Frey pointed out that Americans are moving from traditional sunny areas in the west and south such as Florida, Texas and California to new sunny areas in the inland such as Arizona, Nevada, Georgia and Tennessee. Consumerism harms the environment, and the population growth in the United States will also have a great impact on the environment. According to the research report of the Center for Environment and Population, an independent research institution, the United States is the only industrial country with a rapidly increasing population in the world. The high birth rate and high consumption of natural resources also have a huge adverse impact on the environment. As we all know, the United States has 5% of the world's population, but it occupies 25% of the world's resources, more than four times the world average. Accordingly, the amount of garbage produced by Americans and the amount of carbon dioxide released by Americans are two times and five times the world average, respectively, and they are the main "contributors" to global warming. A landmark moment in China's population history.
