Despite the ruinous housing crisis just a few years ago, the federal government still keeps the suburban sprawl machine humming.

About 85 percent of federal subsidies for housing flow to single family homes, according to a recent report from Smart Growth America, though only about 65 percent of Americans are homeowners and the majority of renters live in multi-family housing. The ultimate sprawl subsidy just might be the mortgage interest deduction. Not only is this baby completely regressive — the vast majority of subsidies flow to households with incomes greater than $200,000 — as you can see in the above map, this money tends to flow to areas where everyone is dependent on a car.

See those donut holes? Inner-city areas with low rates of homeownership, low incomes (and thus fewer residents who itemize deductions), and relatively lower property values are receiving far less of America’s fattest housing subsidy — the mortgage-interest personal income tax deduction (see previous discussion) — than their better-off suburbs. The sprawl subsidies continue apace.

The bigger picture is that this is a subsidy that overwhelmingly benefits wealthy people who have expensive houses, and big mortgages to match — and thus benefits “coastal elites” more.
