1920 USA Regions Population

Urban population first-time majority.

By 1920, the United States population reached roughly 106 million, reflecting significant regional shifts and dynamic growth patterns. The **Northeast** remained the most densely populated region, its industrial cities like New York, Boston, and Philadelphia serving as magnets for both European immigrants and internal migrants seeking factory work and urban opportunities, leading to continued high growth and urbanization. Similarly, the **Midwest** saw significant expansion, propelled by its thriving agricultural sector alongside burgeoning industrial centers such as Chicago and Detroit, which attracted a diverse immigrant base. In contrast, the **South** continued to be largely rural and agrarian, experiencing slower overall population growth compared to the industrial North; however, this period also saw the nascent stages of the "Great Migration," as African Americans began moving northward in search of economic and social advancement. The **West**, while still the least populated, was the fastest-growing region percentage-wise, drawing settlers with opportunities in agriculture, mining, and emerging cities like Los Angeles and Seattle, reflecting continued westward expansion and resource exploitation. Overall, the nation was experiencing a pronounced shift from rural to urban living, with regional populations reflecting distinct economic drivers and migratory patterns.
