The migration balance in the Grand Strand deteriorated between 2021-22 and 2022-23

the Grand Strand · Data as of 2026-09-06 · 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.

Methodology

Source:

U.S. Internal Revenue Service, Statistics of Income Migration Data, county-to-county inflows, 2021-22 and 2022-23

Measure

Net households, ranked highest first across Georgetown, Horry, SC (63 ranked in total).

How the headline figure is computed

Net households (in minus out) across the 63 counties the IRS disclosed in both directions in both the 2021-22 and 2022-23 vintages: 1,270 against 1,622.

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.
