<p>During the first two-thirds of the 20th century, millions of Black rural Southerners moved to cities—usually to the ghettoized urban cores of cities—in the phenomenon known as the Great Migration. By 1960, however, the Black population was substantially urbanized and began to migrate in large numbers from one metropolitan area to another. This migration has been little studied. Using restricted census data and multinomial regression models, we find that intermetropolitan Black movers were far more likely than Black movers within metropolitan areas to settle in neighborhoods with majority White populations. Black intermetropolitan movers were less segregated from the White population compared to both intrametropolitan movers and non-movers across all the largest U.S. metropolitan areas, including those with the highest levels of residential segregation. These movers are thus important players in the story of late 20th century housing segregation, and may provide a valuable, and hitherto overlooked, barometer of how, over time and across different regions of the country, the openness of housing to entry by Black households changed and evolved.</p>
