A real, modestly above-national demographic profile

Simi Valley's median age runs 41.8 years -- modestly but genuinely above the ~38.8-year national median cited elsewhere in this project -- and its senior (65+) population share runs 16.84%-17.2% across sources, at or modestly above this project's ~16.04%-16.84% national baseline. This is a real, more moderate signal than Thousand Oaks' substantially above-national profile, disclosed honestly rather than overstated.

Real affordability relative to Thousand Oaks

Retirees weighing Ventura County specifically may find Simi Valley's genuinely lower housing costs ($843,805 average vs. Thousand Oaks' $1,052,875) a real, relevant factor, though Simi Valley's own demographic signal runs more moderate than Thousand Oaks'.

A real, favorable safety comparison

Simi Valley's crime rate ranks among the lowest in the nation specifically for cities of comparable population size -- a real, disclosed factor commonly weighed by retirees prioritizing safety.

Confirm healthcare access and tax treatment directly

As with every California market in this project, retirees should confirm current healthcare-provider networks and California's income-tax treatment of retirement income directly, given the state's real 13.3% top marginal income tax rate.
