20th century mass migration from global south to global north
In the long time ago, there was a huge migration from Southern America to Northern or Eastern America called “The Great Migration”. The Great Migration was the movement or migration of more than 6 million people to North America. Most importantly all 6 million people are not an ordinary people, their skins are black. Yes, they are the 6 million blacks who moved to the global north.

The whole migrations causes from just one person, Abraham Lincoln on January 1, 1863. He proclaimed an executive order which is called “Emancipation Proclamation” in 1863. It proclaimed a freedom of almost 3.1 million out of the total slaves number four million, and immediately free fifty-thousand slaves after the proclamation. When it was signed in the 1863, less than eight percent of the blacks were living in the north part of America or USA. Then thirty-seven years later in 190s0, the situations haven’t changed much yet. There are still more than ninety percent living in the Southern part of United States of America.


Between 1910s to 1930s, the African American population grew by 40% in the Northern America. More importantly those changes of population were highly happened in the major cities such as Chicago, Detroit, New York city and Cleveland. Those cities had some biggest increases in the early 20th century. Now those blacks who were free from slaves system, they gained rights to have a jobs, gain their lands, and able to migrate to Northern America. They were once live in the urban before, and now they were able to move into the cities, in the Northern America. There is also an estimation that more than 400,000 women migrated to the Northern America since 1916 to 1918. They took this chance to take an advantage of a labor shortage in the wage of World War I. However, this event leads to major changes of population in Northern and Southern America’s population.
In 1910s, the African-American population in Detroit was only 6,000. Then the Great migration and other migration from Eastern and Southern Europe began. These events changed the city’s population dramatically, and it became Northern America’s fourth largest in population. After that around 20 years, African-American population increased to 120,000.

In 1900, Chicago has a total population of 1,698,575. Then twenty years passed, in 1920 Chicago’s total population had increased by 1 million. From the free of slaves in 1863, it can change so much in the populations. After the second wave of the Great Migration in 1940 to 1950, the African-American numbers has increased again from 278,000 to 813,000. That make a huge different from before, and those population live in the cities.
The Great Migration also helps out in educated blacks people. When they are educated, they will be able to find jobs and money, or even have a family. Between 1910 and 1920, numbers of employed blacks are doubled from 500,000 to 901,000. A free of slave gave freedom to every single black.
