As young adults, the Millennial generation arrived as the largest and most racially and ethnically diverse generation in U.S. history. These unique demographic characteristics, along with more progressive self-reported views on racial and ethnic issues, have prompted some to label this generation as a demographic bridge to America’s diverse future. This article examines whether these unique characteristics translate into greater neighborhood racial diversity and integration. Specifically, this study sets out to answer whether Millennial young adult neighborhoods are more racially and ethnically diverse and located in less segregated metropolitan areas than the young adult neighborhoods of prior generations. Using 1990-2019 Census and American Community Survey data, we find a mixed story. On the one hand, young adult White Early Millennials were living in neighborhoods with similar or slightly higher diversity levels, and metropolitan areas with similar or slightly lower segregation levels compared to White young adults in prior generations. On the other hand, young adult White Late Millennials tend to live in more segregated neighborhoods, and in most cases, their segregation levels surpass those for White young adult Gen Xers. These mixed findings provide moderate support for the perspective that the Millennial generation is a bridge to diversity, albeit not the final destination. There is evidence of positive changes towards residential racial integration, but resilience in segregated patterns still remain.
