The Equity Factor

Mass Transit Investment Also Matters for Economic Mobility

A new study found that geography plays a huge part in upward mobility. Investment in mass transit is a big part of the puzzle.

Geography is a strong indicator of economic upward mobility, according to a new study from leading American economists. The researchers mined millions of anonymous earning records to compare upward mobility across metropolitan regions in the U.S. Where exactly you grow up has a large bearing on what tax bracket you might climb to as an adult.

That might sound like common sense, but until now there hasn’t been strong data to prove it. The researchers found that upward mobility is much higher in cities where poor families are more integrated into mixed-income neighborhoods. In other words, living in a neighborhood where people hold all sorts of jobs and earn varied wages gives poor children a better chance of digging themselves out of poverty and earning more as adults.

This is an idea I’ve been thinking about for a while, and wrote about earlier this month in a piece about another recent study that pointed to inclusion as the significant predictor of economic success in cities:

In 2006, Federal Reserve economists conducted an analysis of about 120 metro areas across the U.S. by looking at variables that influence local economic growth. The result? “A skilled workforce, high levels of racial inclusion and progress on income equality correlate strongly and positively with economic growth,” Benner and Pastor write.

This new study, which the New York Times outfitted with some amazing interactive graphics, essentially proves that theory: Low-income kids living in cities where people of a mix of incomes live in closer proximity have a better chance of succeeding than kids in more economically segregated cities.

But the Times, which spoke with an Atlanta area woman about her insanely long commute (“a bus, two trains and another bus”), got us thinking: How much does easy access to transit foster upward mobility? The study ranked 30 cities according to the chances of rising up if you were raised in the bottom fifth of income earners (that is, if your parents make less than $25,000 a year). We looked at the top five cities and bottom five cities on the list and calculated the per-capita investment in their regional mass transit authority’s operating budget.

Top Five Cities

  • San Jose
    Santa Clara Valley Transportation Authority
    Annual operating budget: $341.7 million
    Per capita spending: $381.67 $181.68
  • San Francisco
    San Francisco Municipal Transportation Agency
    Annual operating budget: $851.1 million
    Per capita spending:$1030.55
  • Seattle
    Sound Transit
    Annual operating budget: $212 million
    Per capita spending: $343.87
  • San Diego
    San Diego Metropolitan Transit System
    Annual operating budget: $243 million
    Per capita spending: $76.48 $123.97
  • Pittsburgh
    Port Authority of Allegheny County
    Annual operating budget: $372.1 million
    Per capita spending: $1215.17 $262.92

Bottom Five Cities

  • Atlanta
    Metropolitan Atlanta Rapid Transit Authority
    Annual operating budget: $426.1 million
    Per capita spending: $250.58
  • Detroit
    Detroit Department of Transportation
    Annual operating budget: $128 million
    Per capita spending: $181.30
  • Cleveland
    Greater Cleveland Regional Transit Authority
    Annual operating budget: $237 million
    Per capita spending: $158
  • Cincinnati
    Cincinnati Metro
    Annual operating budget: $91 million
    Per capita spending: $306.86
  • St. Louis
    Metro Transit St. Louis
    Annual operating budget: $249 million
    Per capita spending: $782.595 $161.68

Now, it’s worth noting from the outset that these numbers don’t tell the whole story. The San Francisco stats only include Muni’s operating budget, not BART’s, which brings many workers of various economic backgrounds into San Francisco every day. I’ve ridden both San Diego and Detroit’s mass transit, and though this number might lead you to believe that Detroit’s is better or a larger priority for the city, it’s not. San Diego’s transit was much more pleasant and timely, but those buses don’t have to travel the 139 square miles that make up Detroit’s vast footprint. Seattle and Pittsburgh are more reliant on cars, yes, but it can’t be denied how much money they’ve invested in regional transit. Seattle, much like San Francisco with BART, has two regional transportation authorities.

But even if the numbers are raw and rudimentary and have a couple outliers (St. Louis San Jose and San Diego, specifically), it’s still worth considering. It seems fairly simple: When everyone has access to some form of mass transportation, it gives them access to jobs they might not otherwise have applied for.

This is part of the problem in Detroit now. There are many Detroiters looking for jobs, but few jobs exist in the city. There are jobs in the surrounding suburbs, but no reliable form of transit to get there without a car.

If a region allocates more resources to mass transit, it gives residents in the urban core a better chance of climbing to a higher income bracket. Instead, we have large concentrations of poverty across the country with few reliable transportation options, and little chance at either physical or economic mobility.
