How this list is built
Every row is a published foreign-resident share observation measured in %, ranked highest first. The values were observed between 2025 and 2026. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.
- Compare the displayed value, unit, source date and geographic grain together.
- A city label does not change a regional observation into a city measurement.
