No. A racial disparity is evidence of a difference in outcomes, not by itself proof of what caused it. Systemic racism can be a serious explanation to investigate, but establishing it requires a defined mechanism and evidence that connects that mechanism to a particular outcome, population, place and period.
What does a disparity show—and what does it not show?
A disparity is an observed difference between groups in an outcome, such as health, education or another measure. It describes a pattern. The pattern alone does not identify the process that produced it, whether that process is systemic racism, another factor, several interacting factors, or some combination.
That distinction cuts both ways. A disparity alone does not prove systemic racism caused it; nor does an association with another factor prove that factor fully accounts for the difference. Causal claims need evidence linking a specified mechanism to the outcome. The relevant evidence depends on what is being explained, for whom, where and when.
What do “systemic” and “structural” racism mean?
These terms describe complex processes, not measurement-ready variables with one universally accepted definition. Researchers need to say what mechanisms they mean and how they will observe or measure them. Otherwise, a measure may capture something related to the concept without actually representing the claim being tested.
#1 Best Overall
A 2025 Annual Review of Public Health review describes systemic racism as “a complex, interconnected, and dynamic system” and argues that researchers must operationalize the processes underlying racial inequities. It also emphasizes that measurement should fit the theory and account for how processes unfold over time, including across life-course trajectories. A measure that does not match the proposed mechanism can undermine the validity of a conclusion.
Definitions also vary by framework. The UK Commission on Race and Ethnic Disparities’ 2021 report distinguished systemic racism, which it described in terms of discriminatory processes across interconnected organizations or wider society, from structural racism, which it framed as the continuing effects of historic processes on organizations and societies. Those are the Commission’s definitions, not a universal agreement on terminology.
What other factors might matter?
Factors such as geography, class, sex and family experiences may be relevant to some disparities. Whether they explain a particular outcome is an empirical question: it cannot be settled by listing plausible factors or finding that one of them is associated with the outcome. Social and policy conditions can interact, and the same factor may matter differently across populations, places or periods.

Those are claims within the Commission’s framework; they do not establish the cause of any specific disparity without evidence about that outcome.
Rank #3
Calling a disparity “unexplained” is not the same as proving that systemic racism is absent. It means the available evidence has not conclusively established its causes. Conversely, identifying a contributing factor does not automatically show that it accounts for the whole difference or that other mechanisms played no role.
How do researchers measure structural racism?
There is no single measure that captures every pathway. The Urban Institute’s 2023 review of quantitative empirical research on structural racism and health describes three broad approaches. Their usefulness depends on the question and the theory behind the analysis.
| Approach | What it examines | Key consideration |
|---|---|---|
| Geographic | Patterns measured at a geographic level, such as differences between places. | A place-level measure does not automatically establish which process produced the pattern or how it affected each individual. |
| Self-reported | Information people report about their experiences. | It addresses reported experience, but the measure still needs to fit the mechanism being studied. |
| Specific-policy | A defined policy or policy-related mechanism. | It can make the proposed pathway more concrete, but findings about one policy do not measure every other pathway. |
The Urban Institute report reviewed 70 articles published in the preceding 10 years, focusing on how structural racism was operationalized as an independent variable in health research. That is a count of articles reviewed—not 70 studies proving a causal effect. The report’s conclusion is methodological: approaches can be combined, but none resolves every measurement challenge. As its authors put it, “No single approach can overcome all the challenges inherent to measuring structural racism.”
A 2024 scoping review in Epidemiologic Reviews, covering literature from 2019–2021, likewise describes research linking structural racism to racial health inequities as underway but still at an early stage. It highlights continuing uncertainty about mechanisms and quantitative measurement. This is not a finding that there is no evidence; it is a reason to be precise about what particular evidence can establish.
Best Value
How can you assess a claim about a particular disparity?
Use the same questions whether a claim attributes a disparity to systemic racism or to another explanation. These checks reflect measurement guidance in the 2025 reviews by Brown and colleagues and by Brown, Homan and Ray, and in the Urban Institute’s 2023 report.
- Define the outcome and comparison. What exactly differs, between which groups, and how is the outcome measured?
- Specify the proposed mechanism. Name the process said to produce or contribute to the difference. A broad label alone does not explain how the outcome arose.
- Check whether the measure represents that mechanism. Is it a direct measure, a proxy, a report of experience, a geographic indicator or a measure of a particular policy? What does it leave out?
- Check the context. Do the population, geographic level and historical period fit the claim? A measure or result from one context should not be generalized automatically to another.
- Ask how causes are distinguished. Does the analysis consider confounders, mediators and interactions? An associated factor may be a cause, part of a causal pathway or a marker of other conditions; those possibilities are not interchangeable.
- Look for convergence. Do different methods, measures or data sources support the same interpretation? The 2025 Annual Review of Sociology review argues for theoretically grounded measures and methodological pluralism, including triangulation across frameworks, data and methods.
These questions do not turn a complex issue into a simple score. They make it easier to see whether a conclusion follows from the evidence presented—and how narrowly that conclusion should be stated.
What do rising research counts and citations tell us?
They tell us that scholarly attention has grown, not that causal certainty has grown by the same amount. A 2022 article by Adkins-Jackson and coauthors reported that a PubMed query at the end of 2021 showed an over 50-fold increase in citations of papers on “structural racism” and “health” over the preceding five years. That is a measure of citations returned by a search, not a measurement of racism, the size of a disparity or proof of a causal effect.

The UK Commission’s framework concerns the UK and spans multiple policy domains; it is a contested official position, not a universal verdict on how to interpret disparities elsewhere. Any sound causal assessment must match its claims to the outcome and context actually studied.
