  • AA, African–American; CrI, credible interval; DIC, deviance information criterion; ICC, intraclass correlation; PCV, proportional change in variance relative to model with age of housing stock and block group location.

  • *All models except the empty model contain the variables of age of housing stock and block group location in St Louis City or County.
