What is the population of the world?

The total population of the world is 7 billion.

Since the Black Death and the Great Famine in Europe in 1950s, the world population has been increasing. 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.

Distribution characteristics

(1) The distribution of population growth is unbalanced in time and space: the time to double the population in this century is shortening; The growth rate varies greatly between continents and countries.

(2) The world's population is mainly concentrated in the northern hemisphere and the eastern hemisphere, and concentrated in the middle and low latitudes and coastal areas.

(3) World population structure: the population is aging rapidly.

(4) World population migration: large-scale population migration in modern times: Europe immigrated to America, Australia and New Zealand, Africa immigrated to America, and Asian countries immigrated.

(5) Population problem: the population is growing too fast, and the population is over-urbanized in the process of urbanization.
