Networks and Race

Racism in America

  • Overt, animus-based racism has declined a lot

But there is still lots of racism

  • Some is psychological
    • Unconscious biases
    • Homophily
  • Some is “structural” and a result of past racism
    • Examples in the built environment?
    • In education?
    • In hiring?

Networks and racism

  • How can networks produce or maintain racially biased outcomes?
  • How does this tie into ideas about social/cultural/economic capital?
  • How can we use what we know about networks to reduce racial inequality?

Networks matter a lot

  • In the 90s, people were given vouchers to move to lower poverty areas
  • Chetty at al. found that children did better as adults the longer they lived in higher income areas
    • Why? One (the best!) explanation is that people gain greater social capital
    • Additional evidence from Chetty et al (2022), which shows that living somewhere where friendships have high “economic connectedness” predicts upward mobility.

Takeaways

  • Networks provide a hidden inertia to society, reproducing the world as it is
  • Differences in economic capital or cultural capital are more visible
  • Our achievements are partially a function of our undeserved social networks
  • Worth thinking about “network equality”
