People choose partners based on family background, not education levels

Study finds partner similarity in education is driven by shared family backgrounds, not just education levels.

Why it matters

  • Understanding partner selection can influence social mobility and inequality.
  • It reshapes how we see education transmission across generations.

By the numbers

  • Over 1.5 million individuals from 212,070 extended families were studied.
  • Only 38% of partner similarity in education is due to genetic factors.
  • 62% of parent-child similarity in education is genetic, 38% environmental.

The big picture

  • Social homogamy, or matching based on family background, is more influential than education itself.
  • This has implications for social inequality and mobility.

What they're saying

  • Comments note that this explains why highly educated people might partner with less educated individuals who share similar upbringings.

Caveats

  • Study uses Norwegian data, which may not generalize to other populations.
  • Models don't reveal specific mechanisms behind environmental effects.

What’s next

  • Further research needed to identify precise mechanisms behind these patterns.
  • Understanding these processes can help address social inequalities.
