Recently the NAHB’s Eye on Housing site together a heat map that shows owner-occupied home improvement spending by zipcode. These numbers are garnered from a statistical model relating improvement spending to five key variables (number of homes in the area, the share built in 1960s, share built in the 1970s, owners’ average income and level of education) for calendar year 2015. The estimates show total spending on improvements, as well as improvements per occupied home in the area, in each zip code.
