How to read this list Systems serving the highest combined percent of non-white residents and households below 200% of the Federal Poverty Level. Within-size-class percentiles are used to neutralize the confound of system size. A cap of five systems per state is applied to produce a nationally-representative list. See the methodology page for calculation details.

These 50 Minnesota water utilities serve populations with the highest combined percent of non-white residents and households below 200% of the Federal Poverty Level. Within-size-class percentile rankings neutralize the confound of system size; no geographic cap is applied at the state level because all utilities are within a single state.

How to read this ranking

Each row links to a full utility profile with violation history, lead testing results, and service-area ZIPs. The demographic context columns are from independent data sources (ACS, not EJScreen) and are provided for readers who want to examine equity patterns alongside the operational data.

Frequently asked questions

What does the "equity score" mean?

A 0-100 composite that combines two within-size-class percentile ranks: (1) percent of population served that is non-white (Census ACS B03002), and (2) percent below 200 percent of the Federal Poverty Level (Census ACS C17002). Within-size-class comparison (small, medium, large) is used because small rural systems and large urban systems have structurally different demographic profiles; mixing them in a single ranking produces a methodologically weak list dominated by size rather than disparity.

Why is the list capped at 5 systems per state?

Without a cap, the list concentrates in states with large numbers of historically disadvantaged small-to-medium systems (Texas, California). A geographic diversity cap produces a more nationally-representative snapshot. Per-state rankings, if available, show the full within-state comparison without a cap.

Does this claim discrimination?

No. It reports a demographic fact: these water utilities serve populations that are more non-white and lower-income than the national median, after controlling for system size. Causation — why that pattern exists — is a separate research question requiring different data and methods.
