What makes Hamilton County different: Hamilton County has had no hospital of its own since the former Hamilton County Memorial Hospital sold its operating assets to Columbia/HCA in 1994, so its roughly 3,300 Medicare beneficiaries rely on out-of-county facilities -- the full-service HCA Florida Lake City Hospital in Columbia County and the critical-access Madison County Memorial Hospital, plus an ER-only HCA Florida Suwannee Emergency in Live Oak (the former Shands hospital, converted to emergency-only in 2020). Its senior share is unusually low for Florida because the population includes the ~1,177-capacity Hamilton Correctional Institution in Jasper and a phosphate-mining workforce (Nutrien's White Springs operation employs roughly 600+ near White Springs), keeping the median age at about 41.
