The counties the San Marcos-New Braunfels market takes the most households from, net

the San Marcos-New Braunfels market · Data as of 2026-09-23 · ALEX Intelligence

Read this carefully: A county appears only where the IRS disclosed the flow in BOTH directions; a one-way disclosure would make a net figure that is really a missing number. The IRS withholds county-to-county flows below its disclosure threshold, so a county missing from this table is one whose flow was too small to publish, not one nobody moved from. Every total here is a total of disclosed flows and is therefore a floor.

Methodology

Source:

U.S. Internal Revenue Service, Statistics of Income Migration Data, county-to-county inflows, 2022-23

Measure

Net households, ranked highest first across every U.S. county the IRS disclosed a flow with in BOTH directions against the San Marcos-New Braunfels market (Comal, Hays, TX) (45 ranked in total).

Universe

Every U.S. county the IRS disclosed a flow with. Counties whose flow fell below the IRS disclosure threshold are absent from the source file altogether, so this ranking is of disclosed flows and its totals are a floor rather than a complete count of movers.
