Why are white people and black people so different in the world?

Mainly due to historical reasons, as well as latitude factors.

The race in North Africa (mainly including Egypt, Libya, Morocco, Algeria, and Tunisia) is mainly Caucasian. More than 70% of the people there are Arabs, and Arabs belong to The main reason for the white race is the expansion of the Arab Empire in history, and all of North Africa was included in the empire's territory. Going further back, the Persian and Roman empires once occupied all of North Africa, attracting huge numbers of Eurasian immigrants.

Let’s talk about South Africa again. There are 38.5651 million black people in South Africa’s population, accounting for 79.2% of the population, 4.3792 million people of color, accounting for 9% of the population, 1.2435 million Indian/Asian people, accounting for 2.6% of the population, and white people. 4.4992 million, accounting for 9.2% of the population. The black people mainly include 9 tribes, including Zulu, Xhosa, Swazi, Tswana, Northern Sotho, Southern Sotho, Tsonga, Venda, and Ndebele. Whites are mainly Afrikaners of Dutch descent (about 57%) and whites of British descent (about 39%). Colored people are the mixed descendants of whites, indigenous people and slaves during the colonial period. Asians are mainly Indians (About 99%) and Chinese. As can be seen from the above, the main historical reason for whites and colored people is European colonial rule, and Asians are mainly immigrants for more than a century. However, because whites dominate South African society, most of them are. They live in cities, and the vast majority of black people are either urban poor or live in rural areas. Therefore, most of the people who appear on TV are white South Africans.
