What causes the concentration of well-educated couples in big cities" A new study from the Journal of Labor Economics disputes prior research suggesting power couples migrate to large MSAs. Instead, the researchers argue that college-educated singles are more likely to move to big cities where they meet, date, marry, and divorce other college-educated people. In other words, power couples don’t move to big cities intact – they’re formed there. This finding has important implications for city planners hoping to attract a well-educated workforce.
In 1970, 39 percent of power couples lived in a metropolitan area of at least two million residents. By 1990 this number had grown substantially: Fifty percent of all power couples lived in a big city. In contrast, couples in which neither spouse has a college degree have the lowest probability of living in a large city and the lowest rate of increase, growing from 30 percent to 34 percent in the same twenty year period.
Using data from a large-scale statistical study of 4,800 families (Panel Study on Income Dynamics), Janice Compton (University of Manitoba) and Robert A. Pollak (Washington University and National Bureau of Economic Research) argue that couple migration patterns to large metropolitan areas are influenced gendered determinants – couples in which the man has a college degree are far more likely to move to a metropolitan area than couples in which only the woman has a college degree.
The researchers analyzed data from men aged 25-39 and women aged 23-37, including all married couples who live together and all unmarried heterosexual couples who have lived together for at least one year. They found that migration patterns for “part-power couples” in which the woman is a college graduate are statistically similar to couples in which neither partner is college educated.
“Part-power couples” with a better educated wife are also less likely to migrate from one large metropolitan area to another large metropolitan area, and are more likely to migrate from a large metropolitan area to a mid-size metropolitan area, the researchers found.
“We find that power couples are not more likely to migrate to the largest metropolitan areas and are no less likely than other couples to migrate from such areas once they are there,” write the researchers. “The observed trends in location patterns are primarily due to differences in the rates at which power couples form and dissolve in cities of various sizes rather than to the migration of power couples to the largest metropolitan areas.”
Indeed, even during the 1990s when the proportion of power couples living in metropolitan areas dropped, the percentage of college educated single men and college educated single women living in big cities increased modestly.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
