The preliminary results of this study were published September 25, 2018. It has since been updated for clarity and better visual context.

Absent context, the cost of housing doesn't tell you very much about affordability. Half-a-mil for a 3-bedroom condo in Manhattan is unheard of, whereas half that for a home in Karachi is five times the going rate. For our second 2018 Global Basic Needs Comparison series, we evaluate global housing costs by providing context that matters. For each city evaluated, we include median cost of housing for a typical family (bar), as well as the ratio of median house price to median after-tax income (line).
