  • Interesting maps: a Moral Topography of Portland “The [1913] report found, specified per type of dwelling, only 22 of 80 apartments, merely 5 out of 59 hotels and no more than 71 out of 408 rooming and lodging houses to be ‘moral’.”  If you cynically expected that “immoral” didn’t refer to racial discrimination, rent-gouging, unhygienic conditions, or lack of fire escapes, you were right.

  • An interactive display of US lifetime earnings for various groups by education and gender. The underlying data are good, but there’s inevitably an assumption that the correlations with education are broadly a result of education (including social status and networking effects) rather than selection for existing differences.
