The growth of America's urban population has fluctuated due to various factors, including economic shifts, housing availability, and migration patterns. Economic downturns can lead people to seek opportunities elsewhere or move to suburban areas for affordable housing.

Social dynamics and preferences, like the desire for more space or a rural lifestyle, also contribute to these variations.
