Index overview

What the Civil Rights Index Measures

The NCRRRI Civil Rights Index is a composite measure of civil rights conditions across all 50 states and the District of Columbia, updated annually. It aggregates quantitative indicators from nine federal datasets and NCRRRI's own field research into a single 0–100 score for each jurisdiction, where 100 represents full equity and lower scores indicate greater documented disparities.

The index is organized into six thematic categories — Voting Rights, Housing Equity, Criminal Justice, Education Access, Employment, and Healthcare Access — each weighted by its relative contribution to civil rights outcomes as established in the peer-reviewed literature. Category scores are themselves composites of between four and eight sub-indicators drawn from primary federal data sources.

The index is designed to be descriptive, not prescriptive. It documents conditions as measured by available data; it does not assign causation or recommend specific policy responses. NCRRRI publishes the full indicator dataset alongside the composite scores so that researchers, advocates, and policymakers can conduct their own analysis.

City-level profiles follow the same six-category structure but are calculated from metro-area or county-level data where state-level aggregation would obscure local conditions. City scores are comparable to state scores on the same 0–100 scale.

Data sources

Primary Data Sources

All quantitative indicators are drawn from publicly available federal datasets or NCRRRI's own field research program. No proprietary or paywalled data is used in the index.

Scoring

Score Bands & Interpretation

Scores are grouped into four condition bands. Band thresholds were set by NCRRRI's Research Advisory Committee based on the distribution of indicator values across all jurisdictions in the 2019 baseline year.

Excellent
Moderate
Concerning
Critical
70–100
55–69
40–54
0–39
ExcellentScore range: 70–100

Conditions broadly consistent with equal protection. Disparities exist but are within documented national norms. Continued monitoring recommended.

ModerateScore range: 55–69

Measurable disparities present across multiple indicators. Systemic patterns emerging. Policy intervention warranted.

ConcerningScore range: 40–54

Significant documented disparities. Multiple indicators below national median. Active monitoring and advocacy engagement recommended.

CriticalScore range: 0–39

Severe, compounding disparities across most tracked indicators. Conditions warrant immediate public attention, legal review, and hearing prioritization.

Composite formula: Overall Score = (Voting × 0.20) + (Housing × 0.18) + (Criminal Justice × 0.20) + (Education × 0.18) + (Employment × 0.12) + (Healthcare × 0.12). Each category score is itself a weighted average of its sub-indicators, normalized to a 0–100 scale. Sub-indicator weights are documented in the full methodology paper available on the Transparency page.

Known limitations

What the Index Does Not Capture

NCRRRI is committed to transparency about the boundaries of this data. No composite index fully captures the complexity of civil rights conditions. The following limitations should be considered when interpreting scores.

Reporting lag

Federal datasets are typically published 12–18 months after the reference period. NCRRRI scores reflect the most recently available data, which may not capture conditions in the current calendar year. The 2025 preliminary scores are subject to revision.

Underreporting

Complaint-based indicators (fair housing, EEOC charges, police misconduct) systematically undercount actual incidents. Communities with less access to legal resources or lower trust in reporting systems will appear better than conditions warrant.

Geographic aggregation

State-level scores mask significant intra-state variation. A state with a moderate overall score may contain cities with critical conditions. City profiles provide finer resolution but are limited to the 36 largest metros.

Composite weighting

Category weights reflect NCRRRI's research judgment about relative impact on civil rights outcomes. Reasonable researchers may weight categories differently. The full indicator dataset is available for independent analysis upon request.

Intersectionality

Most federal datasets report disparities by single demographic categories. The index does not fully capture compounding disadvantages faced by people at the intersection of multiple marginalized identities.

Qualitative factors

Lived experience, community trust, and cultural safety cannot be fully quantified. Index scores are a starting point for analysis, not a complete picture. Public testimony collected through NCRRRI hearings provides essential qualitative context.

Public testimony addresses what data cannot.

NCRRRI's public hearing program exists precisely because quantitative indicators cannot capture lived experience, cultural context, or the texture of daily life under unequal conditions. When hearings open in your city, your testimony will become part of the permanent record alongside these scores — providing the qualitative depth that no dataset can supply.
