In-migration to the Grand Strand fell between 2021-22 and 2022-23

the Grand Strand · Data as of 2026-09-17 · ALEX Intelligence

Read this carefully: Only counties the IRS disclosed in both vintages, under the same FIPS code and above a minimum flow in each, are compared, because disclosure thresholds move between years and a flow that appears or vanishes at the margin is not evidence that anybody's behaviour changed. Connecticut is excluded throughout: its counties were replaced by planning regions, so no Connecticut geography is comparable across the change. 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.

Measure

Households (change against the prior vintage), ranked highest first across every U.S. county the IRS recorded sending households to the Grand Strand (Georgetown, Horry, SC) in both the 2021-22 and 2022-23 vintages (163 ranked in total).

How the headline figure is computed

Households arriving from the 163 counties the IRS disclosed in both the 2021-22 and 2022-23 vintages: 9,462 against 10,042. Counties disclosed in only one of the two vintages are excluded, because a flow crossing the disclosure threshold is not evidence of movement.

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.
