Segregation was removed:

By the dawn of the 1970s, the Civil Rights Movement had helped push the Supreme Court to declare segregation in public schools unconstitutional and led to the passage of significant laws like the Civil Rights Act of 1964, which outlawed racial discrimination in public accommodations and employment; the Voting Rights Act of 1965, which prohibited discriminatory voting practices; and the Fair Housing Act of 1968, which barred discrimination in housing sales, rentals, and financing.
