While there is a long history of racial change in the United States, and how this plays out within neighbourhoods, a key recurring question is whether some neighbourhoods are able to achieve and maintain racial diversity, or whether they simply transition to dominance by a new racial group. We test and find evidence of 1631 neighbourhoods across the United States from 1980 to 2020 that exhibit persistent racial diversity (PRD), and assess where this PRD occurs. Our analysis shows that PRD neighbourhoods (PRDNs) are likely to be present in counties with more economic opportunities–that is, counties with higher socioeconomic status (SES). PRDNs themselves, however, tend to be relatively lower SES neighbourhoods within relatively higher SES counties, suggesting that affordable locations surrounded by more economic opportunities may have served as an environment in which diversity can persist over a long period of time in the United States.

美国各地社区持续存在的种族多样性：它发生在哪里？

尽管美国有着悠久的种族变迁历史，以及这种变迁如何在社区内发挥作用，但一个反复出现的关键问题是，一些社区是否能够实现并维持种族多样性，或者它们是否只是简单地过渡到新种族的主导地位。团体。我们测试并找到了 1980 年至 2020 年美国 1631 个社区表现出持久种族多样性 (PRD) 的证据，并评估了这种 PRD 发生的位置。我们的分析表明，珠三角社区 (PRDN) 很可能出现在经济机会较多的县，即社会经济地位 (SES) 较高的县。然而，PRDN 本身往往是社会经济地位相对较高的县内的相对较低的社区，这表明，经济机会较多、经济实惠的地点可能是美国多样性可以长期持续的环境。
