I posted about this last year, and figured some of you might be interested in the newly released 2025 Kentucky county population estimates as well. Kentucky has grown 2.2% since the 2020 Census, putting the state on pace for a higher growth rate this decade (~4.4%) than the previous decade (3.8%).

I attached the 2020 Census populations alongside the 2025 Census Bureau estimates for all 120 counties. From 2020–2025, 73 counties gained population, 46 lost population, and 1 county (Marshall) recorded no change.
