More than 80% of large metropolitan regions in the United States, including the Bay Area, have become more racially segregated in recent decades, with detrimental economic, health and educational outcomes for many communities of color.
That’s according to findings from a UC Berkeley housing study and map released Monday that uses a new methodology to determine the degree of racial segregation in local and regional areas throughout the country. The report goes on to identify vast disparities in income and poverty levels, home values, rent prices and life expectancy between highly segregated communities of color and white communities.
Across the board, segregated white neighborhoods fared the best while segregated Black and Latino neighborhoods fared the worst.
In the Bay Area, for example, life expectancy in largely white neighborhoods (84 years) is more than five years greater than in highly segregated Black and Latino neighborhoods (79 years), the report notes, citing figures from a separate 2019 study, while household incomes and home values are more than double.
But the new report also emphasizes that when Black or Latino people grow up in largely segregated, wealthier white neighborhoods, their life outcomes often improve significantly, underscoring that environment, not race, is in most cases the key determinant of success.
“All of the visible forms of racial inequality that we now recognize — wealth disparities, health disparities, abusive policing, all the disparities in the criminal justice system — they all map to and function because of racial residential segregation,” said report lead author Stephen Menendian, assistant director of the UC Berkeley Othering & Belonging Institute.

COVID-19 brought that into stark relief, he noted. The pandemic disproportionately impacted people in highly segregated communities of color, who are more likely to be low-income front-line workers living in crowded housing conditions.
“If you didn’t have racial residential segregation, most of those forms of racial inequality could be pretty straightforwardly dealt with,” added Menendian, who is white. “It’s something that has persisted and really not gone away for 50 years.”
That finding flies in the face of the prevailing narrative that the United States has grown increasingly less segregated since the civil rights era, when discrimination in housing was technically outlawed by the Fair Housing Act of 1968. And while the U.S. has grown significantly more racially diverse in the last half-century — largely due to the rapid growth of Latino and Asian populations — it has also become more racially segmented, Menendian said.
“And so, what we have basically in almost every metropolitan area is a sort of balkanization patchwork of enclaves,” he said, noting that political polarization also tends to increase in more segregated regions. “What’s different from the 1960s is that there are very few single-race neighborhoods anymore. There are almost no all-white or all-Black neighborhoods. But what has happened is that because of our increased diversity, it’s masked the persistence of segregation.”
