Identity & heritage community ranking

Top Irish communities in U.S. city markets.

Explore where this community is largest and where it represents the greatest share of the local city market. The default ranking lens is 2024 ACS ancestry response (B04006_049E).

Identity discovery only — never a score. Census ancestry, ethnicity, origin, race, and birthplace measures can overlap. V3.4.3 keeps those lenses separate and never adds them together. Identity context never changes the Follow Your Heart Index or any component score.
