Household Migration

Household migration and demographic data—keyed to a national map—for each of the nation’s 50 states and 3,142 counties and county equivalents (mainly parishes in Louisiana and independent cities) using the Internal Revenue Service’s most recently released five-year state-to-state and county-to-county taxpayer migration records, are supplemented with data from the American Community Survey’s five-year estimates over the same time period.

Search, select from the menu, or click on any state, county or county equivalent to view estimates of occupied households, median income, median reported home value, and the most recent years’ taxpayer migration data, covering total number of in-migrating households along with the top three origin geographies (where available).

Note: State-to-state and county-to-county migration data are based on the year-to-year changes in the reported addresses on returns in the Internal Revenue Service Individual Master File system. Data on migration patterns by county, or county equivalent, for the entire United States, include taxpayer inflows and outflows.

ZVA Mobility Distribution Indices

The ZVA Mobility Distribution Indices measure the market activity of a geographical unit—in this case county or county equivalent (mainly parishes in Louisiana and independent cities)—in relation to its share of the total market under examination.

When “ZVA National Mobility Distribution Index” is selected on the map, the counties or county equivalents can be compared one with another across the nation. When “ZVA State Mobility Distribution Index” is selected on the map, the counties can be compared one with another inside the state.

The graphic display of the indices on the map show two factors. The index is indicated by color, ranging from yellow for a low index to red for a high index. The relative volume of in-migrating households is indicated by the transparency level of color—more opaque for higher numbers of in-migrating households.

Available for purchase as part of the ZVA Mobility Distribution Index report (which also includes selected demographic and housing characteristics) are the intra-county, intra-state, and inter-state mobility distribution indices that sub-categorize the ZVA State Mobility Distribution Index, and the internal and external mobility distribution indices that underlie the ZVA National Mobility Distribution Index.

Note: A low index could be the result of a range of circumstances; examples include economic stagnation or contraction, a lack of housing type diversity, high housing costs, low housing turnover, and/or constraints on housing production.
