The number of free persons grew to 78 by 1863 and most all of them were literate. Minnesota being a new state with growing agricultural and industrial needs, it needed more laborers and they came in great migration from the South. During a span of 30 years, and with the passing of the Emancipation Proclamation, the Fourteenth and Fifteenth Amendments and then in 1863, the population grew to nearly 1,400 Black people concentrating in certain areas of Minneapolis and St. Paul eventually forming ghetto areas in the 1930s.
However, because the South continued with denying Blacks many freedoms and enacting the Jim Crow Laws, in the 1900s, there was an even bigger exodus to the North with approximately 1 million Black people moving from the South to escape the Slave life for free opportunities. Abolitionists and free wealthy Black people assisted in the growth of the Black population in Minnesota by creating clubs and societies for Black people to learn of job opportunities, learn trades and for socialization and community activism. The overall Minnesota Black population grew from 1910 at 7,084 to 8,809 in 1920. In St Paul the growth was 7.3% from 3,144 to 3,376 in 1920. Minneapolis had a 51.5% increase from 2,592 to 3,927
During the World War II, many white males went off to war leaving jobs and businesses open for Blacks to capitalize on these opportunities. They developed a wider trade in various fields, grew and expanded with the ability to set their children up with better opportunities. Only 1.7% of Blacks over 10yrs of age were illiterate. In St. Paul, the figure was 1.2% (for the country as a whole the rate was 16.3%).
This search for opportunities continues in Minnesota as the Black population continues to increase by significant numbers. Between 1950 and 1970, the Black population in Minnesota increased from 13,775 to 34,868, a gain of 153%. Minneapolis experienced a record 436% increase in Black population and St. Paul, 388%. As of 2010 there was a Black population of 327,548 (6.2% of the total Minnesota population) which was a change from 2000 to 2010 of 61.4%.
