Past Research Projects

2017 Research Grant Projects

The 2017 County Health Rankings Research Grants funded four innovative projects. These grants serve an important role in strengthening our Rankings methods and increasing their strategic use and impacts. 

Considering health and social services spending (Arizona State University)

During our last round of research grants, Arizona State University researchers found that higher spending for certain social services led to relative over-performance in health rankings when compared to a community’s wealth – and that additional spending led to improved health rankings four years later. Following up on those findings, ASU’s 2017 project examined the feasibility – and characterized the effects – of incorporating detailed measures for health and social services spending into our Rankings.

A detailed look at our methodology (Harvard University)

Researchers from Harvard University looked at the methodology behind our Rankings to review the infrastructure and design of how the Rankings are calculated. The review looked at our framework, weighting scheme, and other attributes for possible improvements.

Factoring in the physical environment (Rutgers University)

The Rankings incorporate a number of measures to evaluate the physical environment – from air and water quality to the built environment. A team from Rutgers University developed a variety of physical environment measures from new data sources, and explored whether measures piloted in New Jersey could be scaled nationwide.

Evaluating education (University of South Carolina)

Building off of the educational and social measures used in the Rankings, researchers from the University of South Carolina evaluated new county-level measures related to school quality, academic achievement, and other education-related topics. The project also explored relationships between these measures and health outcomes.


2015 Research Grant Projects

The 2015 County Health Rankings Research Grants culminated in five innovative projects looking at how to make the most of community data to understand and address what drives local health:

Extending the Rankings to the ZIP code level (Washington University in St. Louis and the Missouri Hospital Association)

Reliable data for a wide variety of health metrics are available nationally, for states, and (of course) for counties, but smaller areas such as ZIP codes is another story. Washington University in St. Louis and the Missouri Hospital Association developed local measures of population health for Missouri counties using data available at the ZIP code level. Data collected by hospitals as well as market research data by Nielsen Claritas were combined and calculated in alignment with the CHR approach. When scaled up, these ZIP code rankings correlated with the County Health Rankings and show a path to refine the health snapshot at the local level.

Does wealth sync with health? (Arizona State University)

Arizona State University researchers using the Rankings data found that while community wealth does correlate with health, it is offset in some cases by the ways counties choose to invest, such as targeting resources to public health initiatives/policies and community health centers. The implications of this show that spending among existing public services may dramatically impact a community’s health.

Mining data to support actionable decisions (New York Academy of Medicine)

Using the Rankings data, the New York Academy of Medicine brought “big data” procedures (machine learning data mining techniques) to identify clusters of counties with different levels of health outcomes based on complex interactions of various health factors that may be related to these outcomes. These analyses offer a straightforward method which may help local county/city officials better design and calibrate actionable and tractable areas to target policies for local health improvement.

The Rankings' impact on policy decisions (Drexel University)

Whether through local health officers or media, news of a county’s ranking can spur change in the form of laws or regulations. But how does that happen? Drexel University’s research explored how the Rankings are used by communities, finding that rankings are useful for educating and raising awareness and are key for local health departments and groups with limited resources working to target their health improvement efforts. Another finding points to Rankings data as a helpful tool for engaging political officials on the need for broader action in partnership with those outside of healthcare when it comes to directing policy decisions that influence community health.

The role of economic stress in well-being (Washington State University and Clemson University, Healthways)

Washington State University and Clemson University in collaboration with Healthways investigated the degree to which county-level factors influence the effect of economic stressors, such as job insecurity or living from one paycheck to the next, on individual well-being outcomes as measured by the nationally representative Gallup-Healthways Well-being Index. Financial and professional concerns have a big impact on psychological well-being and can reveal health impacts beyond just employment statistics. Initial findings suggest that in healthier counties, the effects of income-related stress are diminished while the effects of employment-related stress are magnified in such contexts. This might mean, for example, that in a healthier community experiencing job instability may affect a person’s social contacts or sense of identity and cause more stress compared to a person in a less healthy community.
