Williamson County skews older than Travis, 13.7 percent aged 65-plus versus 11.6 percent, and grew 23.6 percent since 2020. Sun City Texas in Georgetown, a Del Webb 55-plus community of roughly 7,500 to 8,500 homes on about 5,000 acres, anchors that demand.
How Austin families actually use this
Demographics, mostly. Williamson County is 13.7 percent aged 65 and over against Travis at 11.6 percent, and it grew 23.6 percent between 2020 and 2025 — among the fastest growth rates in the country.
Sun City Texas in Georgetown anchors it. The Del Webb 55-plus development runs to roughly 7,500 to 8,500 homes on about 5,000 acres, with approximately 15,700 residents as of 2021. A concentration of active retirees at that scale eventually generates demand for care as residents age in place.
For families, this means Georgetown and Round Rock often have newer inventory and more availability than central Austin, at the cost of a longer drive for whoever visits most.
