Source: IRS Statistics of Income, county-to-county migration data for filing years 2022 to 2023, the latest available. Counts are people (the number of personal exemptions, which the IRS uses to approximate individuals): tax filers plus dependents whose address moved to a different county between the two filing years. People who do not file returns are not counted, and the IRS hides very small flows to protect privacy. Figures are for the whole county, not just the city of Round Rock.
