Neighborhood travel and racial segregation

How people travel to racially different neighborhoods

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Mario Small talks about patterns of people's travel to neighborhoods racially different than their home neighborhood.

In this episode, we cover:
•[00:00] Introduction
•[00:59] Sociologist Mario Small describes how everyday travel can temper residential segregation.
•[01:57] Small talks about how their study tracked peoples' movements and defined travel beyond a person's racial comfort zone.
•[03:48] Small explains the study's results.
•[06:08] He explores why some destinations take people to racially similar neighborhoods and some take people to racially different neighborhoods.
•[07:15] Small shows how "15-minute cities" might inadvertently reinforce residential segregation.
•[08:21] He lists the caveats and limitations of the study.
•[10:34] Conclusion.
