The index does not simply measure crime or personal endangerment, but "digital," "infrastructure," and "health" security as well. Osaka and Tokyo topped the list on health followed by Seoul. The article mentions that some indicators like available hospital beds might reflect cultural differences. The OECD data on
hospitalization stays certainly shows those.
Only sixty cities across the globe were evaluated for these measures. Dallas, for instance, is included, but Boston and Miami are not.
