Question

Difficulty: MediumPostwar Economy, Suburbanization, and Demographics

"The shift of population and industry to the Southern and Western states—a region increasingly referred to as the 'Sunbelt'—has become one of the most significant demographic developments of the postwar era. Enabled by the widespread adoption of air conditioning and accelerated by massive federal spending on defense contracts and military installations, states like Texas, California, and Florida are experiencing unprecedented growth. This migration is reshaping not only the nation's economic landscape, attracting both manufacturing and high-tech aerospace firms, but is also beginning to alter the balance of political power in Congress, shifting influence away from the traditional industrial centers of the Northeast and Midwest."

—Adapted from a postwar economic analysis, c. 1960

The demographic trends described in the excerpt most directly contributed to which of the following political developments in the late twentieth century?

  1. A
    The return to a purely laissez-faire economic model free of federal defense spending and infrastructure subsidies.
  2. B
    The immediate adoption of supply-side economic policies that balanced the federal budget in the 1950s.
  3. A shift in the balance of electoral power that fueled the rise of the modern conservative movement.Answer
  4. D
    The creation of Great Society programs designed specifically to redistribute wealth from northern cities to Sunbelt suburbs.

Answer

A shift in the balance of electoral power that fueled the rise of the modern conservative movement.
The migration of millions of Americans to the Sunbelt shifted the nation's political center of gravity. As these states gained seats in the House of Representatives and electoral votes, they formed the suburban and regional base for the ascendant modern conservative movement, which gained momentum in the late 1960s and culminated in the election of Ronald Reagan in 1980.

Step-by-Step Solution

1
Analyze the stimulus to identify the core historical trend.
The stimulus describes the migration of population and industry from the Northeast/Midwest to the Sunbelt (South and West) during the postwar era, driven by federal spending and technology.
Understanding the demographic shift is the first step in assessing its downstream political consequences.
2
Evaluate how regional population shifts impact the political system.
As the population grew in the South and West, these states gained congressional seats and electoral votes during reapportionment, while the industrial Northeast and Midwest lost influence.
Electoral reapportionment translates demographic changes into shifts in national political power.
3
Link the growing Sunbelt population to late twentieth-century political trends.
The growing suburban and defense-related population in the Sunbelt became a key constituency for the rising conservative coalition of the late twentieth century.
This connects the regional shift directly to the correct political development of the era.
