Has anyone run across a study that examines housing cost as a percentage of income for all income groups? In addition, is this data compared with the income and housing costs growth at different income levels. Time series data would be excellent. Here's what I'm trying to figure out.
Have low income households pay a larger percentage of their income to housing overtime, thus incomes have not grown to meet housing costs? Obviously, the relative change in other "cost of living" factors would have some effect.
Conversely, is the upper middle to upper class (excluding the filthy rich) spending a greater or less portion of their income on housing. If they are spending more, is this a matter of choice or has that market segments housing costs increases at a consistent to different rate than affordable housing? Or are better off households willing to pay more for housing as a matter of choice.
