"A Raisin in the Sun" is generally historically accurate. The play follows the trials of the Younger family as they struggle with how to spend a $10,000 insurance check paid out upon the death of the family patriarch.
The play accurately portrays numerous aspects of African-American life and community in the 1950's. The family lives in Chicago, a city to which many African-American families moved in the '30's and 40's. The family struggles to make ends meet, and Mama's traditional values are at odds with her children's more worldly aspirations. These dynamics reflect the transition that many African-American families were making at the time.
The play is not historically accurate in its portrayal of gender roles in the labor force. Mamma never worked; the entire household was supported by the work of the father. In the 1950's most African-American families were working class, and typically both parents worked outside the home.
