The research

Three independent, exploratory studies of public Texas county data. They describe differences and associations between counties, not their causes, and none has been peer reviewed. Each publishes its data, code and an independent recomputation of every statistic.

• Cardiovascular health

  Geographic Variation in Cardiovascular Health Across Texas Counties

  How do county estimates of cardiovascular conditions, their risk factors and heart disease death rates vary across Texas, do they cluster geographically or differ between metropolitan and nonmetropolitan counties, and how strongly do the risk factors track the outcomes?

• Smoking and lung cancer

  Smoking Prevalence and Lung Cancer Incidence Across Texas Counties

  Is age-adjusted adult current cigarette smoking prevalence associated with age-adjusted lung and bronchus cancer incidence across Texas counties?
