Why are there so few black and yellow people in the world?

Black people account for 16%, yellow people account for 4 1%, and white people account for 43%, mainly because of the population explosion. The high fertility rate in Africa and the negative population growth in Europe and America have changed greatly.

Among the population proportions of the three major races, white people have the largest population, followed by yellow people, and finally black people. The reason why the total population of white people is so large is that white people are also the most widely distributed. In addition to Europe, North America and Oceania, which we all know, white people are mainly distributed, and Central Asia, West Asia and North Africa, where populous South Asia and Islamic countries gather, are also white people.

Black people have the smallest distribution range, mainly in sub-Saharan Africa, while yellow people are mainly distributed in East Asia and Southeast Asia, and there are also some yellow people in South America.

In the past few years, many people can clearly feel that the black population is expanding rapidly. For example, at present, more than half of the newborn population in many cities in France is black, and sub-Saharan Africa is the fastest growing region in the world.

Extended data

Twenty years ago, our geography book said that the black population was only 550 million, but now the black population has actually exceeded1.500 million, and the black population is still growing rapidly at a rate of more than 2% per year.

1990, the proportion of white people, yellow people and black people in the global population was 55%, 38% and 6% respectively. But by 20 19, the proportion had become 5 1%, 3 1%, 17%.

Due to the low population growth rate in China, Japanese, Korean and other countries where the yellow race is mainly distributed, the proportion of the yellow race in the global population will continue to decline. In the next 20 years, the total black population may surpass the yellow race and become the second largest race in the world.

The reason why the black population is expanding so rapidly is that, in addition to the strong fertility and desire of black people, another more important factor is that the economic development level of black countries is generally low, and the birth rate of these countries is very high, so the growth rate of black population will be ahead of whites and yellow people for a long time to come.
