A growing body of research shows Los Angeles to be a region of extreme polarization, where rich and poor live in separate neighborhoods, surrounded by others like themselves.
Demographers at Wayne State University in Detroit recently found Greater Los Angeles to be the most economically segregated region in the country. The study found only about 28% of its neighborhoods to be middle-class or mixedincome, compared with more than half of those in Nashville, Pittsburgh, Seattle and Portland, Ore.
More than two-thirds of L.A.-area residents live in neighborhoods that are solidly rich or poor, according to the analysis, which is based on 2000 census data. That share has been steadily growing for three decades, said one of the study’s authors, George Galster, a professor of urban affairs at Wayne State.
“The situation in L.A. is certainly at the extreme of American cities,” Galster said, adding that every one of the 100 metropolitan regions he looked at has grown more economically segregated over the last 30 years.
The trend parallels a well-documented loss of middleincome jobs in the United States over a generation. But the study found that middle-class neighborhoods are disappearing at a much faster rate than the comparable jobs.
Researchers attributed the faster pace to a kind of self-sorting. In other words, people are moving out of economically diverse neighborhoods to live in areas dominated by their own income group.
“I think that poses real challenges to any society, politically and socially,” Galster said. “The fact that our society is moving to a situation where we don’t rub shoulders on a daily basis means that, more and more, people’s impressions of others will not be formed by personal experience but by images in the media.”
The study defined neighborhoods by residential census tracts, and defined middle income as between 80% and 120% of the metropolitan area’s median.
Los Angeles’ spot on the list can be explained, in part, by two factors that create bulges at each end of the economic spectrum: Large numbers of low-skilled immigrants earning low wages and a rarefied club of wealthy entertainment and business moguls.
Los Angeles County “has more billionaires than any other part of the country. It’s also the capital of the working poor,” said Peter Dreier, chairman of the Urban and Environmental Policy Program at Occidental College.
That wasn’t always the case. A generation ago, the region was a model for the post-World War II, middle-class lifestyle. High-wage manufacturing jobs were abundant, particularly in the aerospace industry. When the industry collapsed in the early 1990s, many middle-class residents left the region. In the meantime, large numbers of immigrants arrived seeking work.
Other changes mirrored national trends, including the development of large, similarly priced housing tracts outside city cores.
Dreier and Galster said government intervention is needed to reverse the trend.
In metropolitan regions that are continuing to grow, such as Los Angeles, they advocated a requirement that developers build a mix of housing, including affordable units for low-income residents.
Known as “inclusionary” housing, that tool has been adopted by dozens of California cities. But in Los Angeles it has been successfully opposed by business groups that have argued it would discourage developers from building in the city at all.
For several years, Flaming has documented the loss of middle-class jobs in the region, as well as the rise of the lowpaying informal economy. Using 2004 data, Flaming found that 15% of households in the county earned less than $15,000 a year, accounting for 2% of the area’s income. At the same time, 7% of households earned more than $150,000, accounting for 27% of the county’s total income.
Households earning the median range, between $45,000 and $50,000, made up one of the smallest segments of the population, less than 5%. Flaming calls it the vanishing middle.
