Looking at the cpi doc [0], shelter makes up 32.86% of the expenditures, which at least at first glance appears realistic. There will obviously be outliers (people living in higher cost of living areas, cities, etc), but I'm curious if you see data that supports a different number.

I'd expect anecdotal numbers from hn to trend towards higher CoL, which likely correlates with spending a higher percentage on housing.
