Why a Matrix Beats Gut Feel
Choosing an elderly home location typically comes down to familiarity or price. But for health-vulnerable elderly, what matters more is: how fast can we reach a hospital in an emergency? Is the air clean enough for weakened lungs? Is Smart Home infrastructure available?
Running the analysis across 5 dimensions reveals a clearer picture than any real estate agent can offer.

Matrix Summary: Choose Based on Health and Priorities
Elderly with heart disease or complex conditions → Bangkok Sukhumvit / Rama 9 Closest hospitals. High cost of living, but the cost of delayed treatment is higher.
Healthy elderly prioritising quality of life → Chiang Mai or Korat (downtown) Balance of hospital access, cost of living, and environment. Avoid Chiang Mai if lung conditions.
Want nature and clean air → Pak Chong (if healthy and family-supported) Best air quality but weak infrastructure and distant hospitals. Requires an Emergency Transport plan.
