Importance: Health care delivery faces a myriad of challenges globally with well-documented health inequities based on geographic location. Yet, researchers and policy makers have a limited understanding of the frequency of geographic health disparities.

Question: Are there geographic health disparities across 11 high-income countries?

Findings: In this survey study using self-reported data from 22 402 participants across 11 countries, the mean number of geographic health disparities across 10 indicators and 3 domains (health status and socioeconomic risk factors, affordability of care, access to care) was 1.9, although there was wide variation among the nations. The US had significant geographic health disparities in 5 indicators, the most of any country, while Canada, Norway, and the Netherlands had no significant geographic health disparities.

Meaning: These results suggest that health policy makers in the US should look to Canada, Norway, and the Netherlands to improve geographic-based health equity.
