Policymakers are often told only the partial story when it comes to health equity, since the numbers are just one of the sources of evidence. To some extent, they rely on data-driven health equity policy to define disparities; however, the context, culture, and lived experience are just some of the parts that are often neglected. In this regard, knowing the limitations of data is as essential to making decisions as the data collection itself.

While the power of quantitative data gives them the ability to pinpoint less productive areas, monitor change, and demand accountability from the very systems in which they participated. One concrete example of this is the CDC’s impressive databases that it uses to draw up maps containing chronic disease rates classified according to race, income, and, even to the extent of zip code. Such data not only identify but also nakedly present structural disparities that would otherwise remain obscure. The cities of Baltimore and Los Angeles, for example, when they make their resource allocation decisions favoring communities with worse asthma or diabetes rates, are thereby taking this evidence as their helper in justifying their actions. So has been the case with various inequities that were very much alive but untraceable due to a lack of measurement.

Nonetheless, it must be acknowledged that data can only reflect what has been defined and documented. For instance, someone who is housing insecure may not get acknowledgment in the health survey if the survey does not account for such a vulnerable group or if it operates in a different language that they cannot speak or understand. This is particularly risky when those making policies depend mainly on figures as they could come up with programs that appear to be effective on paper but later find out that they are failures in real-life situations.

Health equity is nothing short of a complex issue, one of which medical access is just a part. It is a broad issue having the general aspects of accessibility such as trust, culture, and daily experience as the core factors influencing them. People’s identities are often reduced to wide, general categories to such an extent that even the differences among them are smoothed out in most national surveys. The U.S. Census and Behavioral Risk Factor Surveillance System often places different immigrant communities under the broad terms of “Asian” or “Hispanic,” thus hiding the particular needs of each population.

The local context also is a significant factor when it comes to the interpretation of data. A low vaccination rate, for instance, may be an indicator of poor outreach instead of total refusal. If the policymakers regard the data as resistance rather than misunderstanding, they might prescribe the wrong remedy and reinforce the mistaken treatment. To simplify, basically, figures can identify the issue but only illuminate the reason for its occurrence.

Affecting policy that matters requires data collection to be no more than a helping hand to local expertise. Community partnerships, qualitative research, and participatory methods are necessary to provide context for statistics. The Robert Wood Johnson Foundation urges “mixed-method” approaches, where surveys are accompanied by interviews and storytelling. The illumination of how factors like transportation, neighborhood safety, or discrimination affect health outcomes in ways that numbers cannot express is one example of the benefit of these efforts.

Cities that have applied this model, such as Seattle’s Equity and Environment Initiative, demonstrate that the inclusion of resident voices results in more powerful interventions. When data and experience intertwine, the policy becomes not only effective but also considerate.

Data is crucial in pinpointing inequalities, however, it cannot provide full definition of them. When policymakers depend solely on measurements and do not take the views of communities into account, they are likely to strengthen the disparities that they are trying to eliminate. Health equity measuring should involve more than just outcome counting; it should also encompass people’s comprehension.
