Household Income vs. Housing costs
I am trying to derive a measure of the % of household income that is spent on housing. I am using gross household income (fihhmngrs_dv) for household income, as the traditional way of calculating 'affordable housing' is >30% of gross household income being spent on housing costs.
However, I have noticed that quite a few US respondents have quite strange housing cost to household income ratios. Essentially having mortgage or rent payments but no, or next to none, household income. I would assume of this may be people temporarily unemployed or using savings, but these doesn't seem to be the case for quite a few. What do you think could be the explanation of the discrepancy?
