Increasing US urban residential segregation and decline of middle-class communities

A new report by Kendra Bischoff and Sean Reardon for the Russell Sage Foundation and Brown University found that, as a likely consequence of widening American income inequality, fewer and fewer Americans  live in urban middle-class neighborhoods and urban communities are instead increasingly polarized into rich and poor neighborhoods.  They call this increased “income segregation” or “family income segregation.”  Their report studies 117 metropolitan areas with a population of 500,000 or more in 2007 and examines these patterns at the census tract level, covering roughly two thirds of the US population.

This is bad news for the opportunity to build bridging social capital (social ties across race or social class), bad for building any sense that we’re all in this together, and by insulating the rich increasingly from the poor, makes it less likely that the rich will want to take action to help the poor (in the same way as the rich become less interested in public education investment if they send their kids to private schools or become less interested in safe streets if they live in a gated community with a private police force).  This research shows how children are less likely to grow up socializing with and playing with children of other socio-economic backgrounds, especially in an era where mandatory school-busing has come under attack.

These trends are all prior to the 2008 great recession, so it is impossible until 2013 to know whether that exacerbated these patterns or ameliorated them somewhat, and even then we probably won’t know about specific neighborhoods.

Bischoff points out that these segregation indices would change during the recession only if foreclosures or job losses force people to move, then income segregation could change.  For instance, if low- and moderate- income families need to move to lower-income neighborhoods, urban residential segregation would increase (more clustering).  Alternatively, if middle income families lose income, but remain in their homes (or neighborhoods), then residential income segregation would decrease as neighborhoods as increased family income volatility leads neighborhoods to become more diverse in income terms. The American Community Survey may never be able to resolve what happened at low levels of geography.

Excerpt:

As overall income inequality grew in the last four decades, high- and low-income families have become increasingly less likely to live near one another. Mixed income neighborhoods have grown rarer, while affluent and poor neighborhoods have grown much more common. In fact, the share of the population in large and moderate-sized metropolitan areas who live in the poorest and most affluent neighborhoods has more than doubled since 1970, while the share of families living in middle-income neighborhoods dropped from 65 percent to 44 percent. The residential isolation of the both poor and affluent families has grown over the last four decades, though affluent families have been generally more residentially isolated than poor families during this period. Income segregation among African Americans and Hispanics grew more rapidly than among non-Hispanic whites, especially since 2000. These trends are consequential because people are affected by the character of the local areas in which they live. The increasing concentration of income and wealth (and therefore of resources such as schools, parks, and public services) in a small number of neighborhoods results in greater disadvantages for the remaining neighborhoods where low- and middle-income families live.

Key findings, based on Census American Community Survey data:

  • From 2000 to 2007, family income segregation grew significantly in almost all metropolitan areas (in 89 percent of the large and moderate-sized metropolitan areas). This extends a trend over the period 1970-2000 during which income segregation grew dramatically. In 1970 only 15 percent of families were in neighborhoods that we classify as either affluent (neighborhoods where median incomes were greater than 150 percent of median income in their metropolitan areas) or poor (neighborhoods where median incomes were less than 67 percent of metropolitan median income). By 2007, 31 percent of families lived in such
    neighborhoods.
  • The affluent are more segregated from other Americans than the poor are. That is, high-income families are much less likely to live in neighborhoods with middle- and low-income families than low-income families are to live in neighborhoods with middle- and high-income families. This has been true for the last 40 years.
  • Income segregation among black and Hispanic families increased much more than did income segregation among white families from 1970 to 2007. Notably, income segregation among black and Hispanic families grew very sharply from 2000 to 2007. Income segregation among black and Hispanic families is now much higher than among white families.

Read “Growth in the Residential Segregation of Families by Income, 1970-2009” (Sean Reardon, Kendra Bischoff).

See NY Times story, “Middle-Class Areas Shrink as Income Gap Grows, New Report Finds” (11/16/11, by Sabrina Tavernise) which also shows this pattern for Philadelphia, which showed the biggest increase in income segregation over this period as well as the overall decline in middle-class neighborhoods and the rise of poor neighborhoods.

See earlier blog post: “Stalled upward social mobility in the US”

See somewhat related post by Liberty Street Economics (the blog of the Federal Reserve Bank of New York) that shows both that median wages were growing fastest in the high-skilled occupations, and also that job growth was fastest in both the high-skilled and low-skilled occupations and slowest in middle-class job occupation.

Stalled upward social mobility in America [UPDATED 2/14/12]

Rana Foroohar’s cover story in TIME (Nov. 2011) is entitled What Ever Happened to Upward Mobility? Her answer is that it has stalled in the US and fallen behind rates of upward mobility in the US, Sweden or Denmark.  According to Foroohar (and based on a Pew study), a male born in the 1970s into the bottom fifth of the wealth distribution had only a 17% chance of making it to the top wealth quintile.  And while 50% of young males in this low-wealth quintile remained stuck there in the US, it was only 30% in UK or 25% in Denmark and Sweden, so upward mobility was much higher in those nations.  [Swedish economist Markus Jantti led the research project that uncovered these numbers.]

Foroohar (after consulting experts from places like Goldman Sachs) says that China and other emerging countries are driving inequality by taking away good middle class US jobs.   Foroohar believes that the answer lies in more progressive tax rates (with fewer loopholes) and greater investments in public education (which is the engine of economic mobility).

Fareed Zakaria also has three pieces on this: “The Downward Path of Upward Mobility” (Wash. Post op-ed, 11/10/11), a CNN video entitled “Fix Education, Restore Social Mobility” (about how lack of investment in education causing stagnating upward mobility is at heart of Occupy Wall Street movement), and “When will we learn” (TIME, 11/14/11).

Bhaskar Mazumder, of the Chicago Fed, highlights research that he believes shows a decrease in US social mobility from 1980-1990 and then growing less rapidly from 1990-2000 (based on studies of brothers). Mazumder notes that mobility measures are by methodological approach “backward-looking” since they impose a several decade lag before one learns of corrosive influences in society for social mobility; he  notes  that “the gap in children’s academic performance between high- and low-income families has widened significantly over the last few decades. If this trend persists, it would point to reduced intergenerational economic mobility going forward.”

We have been doing work on the connection between income inequality and social inequality among youth (that exacerbates the test score gaps) and will report on that later, but suffice it say that we find a connection between the “blue inequality” (income inequality) and “red inequality” (the ability of college graduates to pass on advantages from a generation to another) that David Brooks writes about.

In November 2011, a variety of non-profit, corporate, academic and media leaders convened to discuss social mobility in the Opportunity Nation summit.  Opportunity Nation has released an Opportunity Index that enables you look state by state or county by county to see how that locality is doing in terms of economic opportunity. And you can see videos of some of the speakers here.  Rick Warren cited an eye-opening statistic: 25% of Anglo kids, 50% of Hispanic kids, & 75% of black kids are growing up today without a stable father in the home (these are out of wedlock births).  This work is picked up in Charles Murray’s Coming Apart and in Nick Kristoff’s “The White Underclass“.

And interestingly, even conservative media venues like the National Review and the FrumForum (here and here) are discussing the decline of social mobility as noted in “Harder for Americans to Rise From Lower Rungs“, citing Republican experts like John Bridgeland.  Even Presidential candidate Rick Santorum has admitted that social mobility up into the middle class is higher in Europe than in the US. Excerpt from Scott Winship’s piece in the National Review here:

The Economic Mobility Project/Brookings analyses break the parent and child generations into fifths on the basis of each generation’s income distribution. If being raised in the bottom fifth were not a disadvantage and socioeconomic outcomes were random, we would expect to see 20 percent of Americans who started in the bottom fifth remain there as adults, while 20 percent would end up in each of the other fifths. Instead, about 40 percent are unable to escape the bottom fifth. This trend holds true for other measures of mobility: About 40 percent of men will end up in low-skill work if their fathers had similar jobs, and about 40 percent will end up in the bottom fifth of family wealth (as opposed to income) if that’s where their parents were.

Is 40 percent a good or a bad number? On first reflection, it may seem impressive that 60 percent of those starting out in the bottom make it out. But most of them do not make it far out. Only a third make it to the top three fifths. Whether this is a level of upward mobility with which we should be satisfied is a question usefully approached by way of the following thought experiment: If you’re reading this essay, chances are pretty good that your household income puts you in one of the top two fifths, or that you can expect to be there at age 40. (We’re talking about roughly $90,000 for an entire household.) How would you feel about your child’s having only a 17 percent chance of achieving the equivalent status as an adult? That’s how many kids with parents in the bottom fifth around 1970 made it to the top two-fifths by the early 2000s. In fact, if the last generation is any guide, your child growing up in the top two-fifths today will have a 60 percent chance of being in the top two fifths as an adult. That’s the impact of picking the right parents — increasing the chances of ending up middle- to upper-middle class by a factor of three or four.

Washington Post-ABC News Poll: http://www.washingtonpost.com/wp-srv/politics/polls/postabcpoll_110311.html   [see questions 16-18]

December 2011 OECD report Divided We Stand: Why Inequality Keeps Rising on how inequality among OECD countries is at a record high over the past 30 years and demands action.

The reports that Zakaria uses to show that mobility is lower in US than in Europe are:
- OECD 2010 report: http://www.oecd.org/dataoecd/2/7/45002641.pdf
- German Institute for the Study of Labor report (2006): http://ftp.iza.org/dp1938.pdf

- Professor Miles Corak (economist at Univ. of Ottawa) compared rates of mobility in a review of over 50 studies spanning nine countries.

- See Scott Winship’s testimony to Senate Budget Committee (Feb. 9, 2012) on inequality and social mobility, and see Jared Bernstein’s and Heather Boushey’s as well.

Two of most startling charts of testimony were one by CBO showing how the income of the top 1% is the one cohort that has done well over the last 40 years in the US economy:

And one showing that, unlike in most countries where progressive taxation is used to curb the excessive inequalities of the market and ease the distribution somewhat, the tax and transfer system in the US actually make inequality WORSE.
