How has COVID-19 changed ‘superstar cities’? A new analysis found that overall mobility in large U.S. cities has yet to return to pre-pandemic levels, and some are also experiencing changing segregation patterns, with potential implications that could last well beyond the pandemic. A new study, recently presented at the GISRUK conference, found that overall mobility in large U.S. cities has yet to return to pre-pandemic levels. Using tools from geographic information system (GIS) analysis and data science, geospatial researcher Andrew Renninger also found that some of these cities are experiencing changing segregation patterns.
