Which statement describes demographic change affecting civil rights?

• A. Movement of millions from the North to the South
• B. Black voters in the North aligned with Republicans during the New Deal
• C. Movement of millions of Black people from the South to urban centers; in the North, Black people joined the Democrats during the New Deal
• D. No significant migration occurred

Answer: (C)

The key idea is how large-scale population shifts reshape civil rights power and policy. The Great Migration—millions of Black people moving from the rural South into urban centers in the North and West—transformed the racial makeup of cities, expanding Black political influence and activism. With bigger, more organized Black communities in urban areas, advocates could push harder for anti-discrimination laws, voting rights protections, and equal access in housing and employment.

At the same time, the New Deal era helped shift Black voters in the North toward the Democratic Party because relief and social programs addressed some of their immediate needs, even as segregation persisted. This combination of a major demographic shift and a realignment of political support strengthened the push for civil rights and laid groundwork for later reforms.

The other statements don’t fit because moving from the North to the South would reduce urban Black populations and the momentum for civil rights; Black voters in the North aligning with Republicans during the New Deal contradicts the observed trend of Black support leaning Democratic during that era; and saying no significant migration occurred ignores the well-documented Great Migration.
