Headlight Data and Avalanche recently developed a free interactive tool that allows users to explore migration trends across the US.
Migration can be measured in terms of total returns, total exemptions, and total gross income. Net migration is measured as the difference between in-migration into the county and out-migration from the county and is based on IRS tax return data.
The data shows that county-to-county net migration is the highest in Travis County, TX (Austin), which gained 24,000 households in 2013 from outside the Austin metro. Travis County gained a remarkable 10,000 more returns than the county in second place. Read more about our analysis in the Austin Business Journal.
Harris County, TX (in Houston) attracted 14,000 new households, followed by Maricopa County, AZ (7,400), Clark County, NV (6,100) and King County, WA (5,100).
County-to-county net migration in terms of Total Gross Income is also the highest in Travis County, TX (Austin), which gained a net of $2.4 billion in 2013 new taxpayers relocating from outside the Austin metro.
Palm Beach County, FL (in the Miami metro) attracted $1.6 billion net new Gross Income, followed by Collier County, FL ($1.4 billion), Maricopa County, AZ ($1.0 billion) and Clark County, NV ($1.0 billion).
