Housing/Income Characteristics by Year

Choose Area to View: 

Affordability is dependent upon both housing costs and incomes in an area. A chart of basic housing and income characteristics is provided including an Housing Affordability Index (HAI) that reflects affordability based on median household income for all housing.

The Housing Affordability Index answers the question, “What is the percent of the typical household income that is required to afford the typical home?”

The chart provides the two components of the HAI that reflect the affordability of sold units and affordability of rent units. In addition, the chart provides adjusted versions of the HAI based on 80% and 60% of median income for all housing, a Lowest-Quartile Housing Affordability Index, Sold Affordability Indexes at the median owner income and at the median renter income, Rental Affordability Indexes at the median owner income and at the median renter income.

See DESCRIPTION OF MEASURES for a more detailed explanation of the additional indexes and chart components.

In addition to the various housing affordability indexes, the chart provides the data components that are used in creating the indexes. These data components include households broken down by tenure (the percent of owners and renters), the annual median household income for all households, owners, and renters, median monthly renter cost (rental units), median monthly owner cost (sold units, based on sales price of new and existing sales from MLS realtor data adjusted for mortgage terms, homeowner’s insurance, and taxes), and median sale price of new and existing sales from MLS realtor data. In addition, the percent of households that are cost burdened (pay more than 30% of income for housing) is provided.
