* 2013–2016: for these years the research database's IRS net-migration figures for Travis County are +39,849 / +121,194 / −33,743 / −55,811 people, while the U.S. Census Bureau's Population Estimates Program puts net domestic migration at +9,472 / +12,153 / +9,169 / +8,606. The swing is confined to flows between Travis County and other states, and the neighbouring Williamson and Hays files show nothing like it, so we treat these years as an IRS data anomaly rather than real moves and leave them out of the charts. Source: IRS Statistics of Income migration data; comparison with Census Bureau population estimates. Years are flagged when IRS net migration differs from the Census Bureau's net domestic migration estimate by more than 20,000 people or three times the Census figure. Flagged years are an IRS data anomaly, not real moves.

IRS SOI public data; cite IRS SOI.Built from year-to-year changes of the filing address on individual income tax returns: returns = households, exemptions = people, agi_k = adjusted gross income in $1,000 (null for 1990-92, which carry no AGI).
