Which country has the fourth largest population in the world?

1. Population ranking of countries and regions (including sovereign countries and inhabited territories, etc. ) has the latest population ranking in the world. The data used in this ranking are based on the statistical data provided by national census authorities and the 20 19 data predicted by the Population Division of the United Nations Department of Economic and Social Affairs. As of March 20 19, the top 10 countries in the world are China (including Hong Kong, Macao and Taiwan), India, the United States, Indonesia, Brazil, Pakistan, Nigeria, Bangladesh, Russia and Mexico.

Second, it kept growing after the Black Death in 1950s and the Great Famine in Europe. There were about 370 million people in the world at that time. Subsequently, due to factors such as war, the growth rate was sometimes fast and sometimes slow. After the end of World War II, from 1960s to 1950s, due to the decrease of factors (such as wars and famines) that caused the population growth to slow down, the world population growth rate obviously accelerated-exceeding 1.8% every year.

Third, this state continued until 1970. From 65438 to 0963, the world population increased by 2.2%, reaching a historical peak. Subsequently, with the development of economy, people's concept of fertility has changed, and the population growth rate has gradually declined. 20 1 1 The annual world population growth rate is about 1. 1%. It is estimated that by 2040, the world population will reach 8 billion.

The current forecast shows that the world population will continue to grow in the next few decades, but it is difficult to estimate the factors such as the decline of birth rate, so it is impossible to get a specific value. It is only concluded that the world population will be between 7.5 billion and 654.38+005 billion in 2050, depending on the rate of birth rate decline. In the long run, it is estimated that the world population will stop growing and decline slowly from 2050 to 2 150. At the same time, some analysts are also worried about the sustainability of population growth.

5. The population problem has been paid more and more attention by the international community. Since 1954, the United Nations has held many world population conferences. The third International Conference on Population and Development was held in Cairo from September 5 to September 3, 1994. More than 5000 delegates from 182 countries and regions attended the meeting. This conference is the first time to link population issues with sustainable development.

6. At the end of the meeting, a program of action was adopted, calling on all countries to strengthen cooperation in the field of population and development and solve common problems facing mankind. 1From June 30 to July 2, 1999, the United Nations held a special session on population and development, which once again recognized the importance of solving the population problem from the strategic height of population and economy, society, resources, environment and sustainable development.

According to the World Population Report published by the United Nations Population Fund in London on July 1995+0 1, the total population of the world in 1995 was 5.7 billion. There are 960 million illiterate people, two thirds of whom are women and 1/3 are children. It is speculated that the annual growth of the global population will remain above 86 million.
