What makes Parker County different: Parker County is one of the fastest-growing exurban counties west of Fort Worth (population ~179,700, about 29,200 residents age 65+). Because Weatherford straddles the Parker/Hood line, area Medicare Advantage figures (connieHealth shows ~45% for the Weatherford ZIPs) overstate the Parker-only rate, which lands nearer one-third as many DFW-transplant retirees keep employer or Medigap coverage. The 103-bed Medical City Weatherford anchors local acute care.
