The Civil Rights Movement's success in gaining federal passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965 renewed constitutional rights, including voting for blacks. Together, these resulted in the most far-reaching changes in New Orleans' 20th century history. Though legal and civil equality were re-established by the end of the 1960s, a large gap in income levels and educational attainment persisted between the city's White and African American communities. As the middle class and wealthier members of both races left the center city, its population's income level dropped, and it became proportionately more African American. From 1980, the African American majority elected primarily officials from its own community. They struggled to narrow the gap by creating conditions conducive to the economic uplift of the African American community.
