CDC CASE STUDY ASSIGNMENT Rising Insurance Premium for the Northeast You are a journalist for the New York Times. Your specialty is research. Some reader’s have written you complaining that their health insurance premiums are going up while that is not the case for people living in the Midwest. Upon calling several insurance companies (at your reader’s prompting), you were told the same thing – “Those residing in the Northeast compared to those residing in the Midwest live a more risky lifestyle in terms of alcohol consumption, driving habits, etc. As such their premiums unfortunately are going up while those living in the Midwest are not.” You have decided to research this and write an article for the newspaper to either confirm or refute this claim by the insurance companies.

You suspect they are not telling the whole story and that the cost difference is most likely a function of the higher cost of living in the Northeast. Upon searching for various data sources to assist you in this effort, you ran across the Center for Disease Control’s “2010 Behavior Risk Factor Surveillance Survey.” This survey is conducted every 10 years and compiles the following information by state:

  • Variable Label SMK: Current cigarette smokers
  • WEI: Overweight (based on government height weight formula)
  • SED: Sedentary lifestyle (less than three 20-minute exercise sessions a week)
  • ACT: No leisure time activity off of the job
  • ALC: Binge drinking (five or more drinks on occasion)
  • DWI: Drinking and driving (after too much to drink)
  • SEA: Seat-belt use (occasionally or never)
  • STATE: U.S. State (alphanumeric)
  • N: Number of people surveyed

About 1,000 people from each state were randomly chosen to estimate the true population percentages. Some data is missing for certain states, denoted with an asterisk. Your task involves: determining which states are in the Midwest and Northeast; weighting survey percentages based on population estimates from 2000; conducting hypothesis tests to assess statistical significance of differences; incorporating census data on median income and education levels; analyzing correlations between these measures and risky behaviors; reviewing recent research on education and life expectancy; examining cost of living differences using online calculators; and creating a final presentation summarizing your data and findings in tables and graphs. Your presentation should include an introduction, data used and how collected, analysis steps, findings, and conclusion, limited to 15 slides. The final report should be in PowerPoint format. Each team member contributes based on a set schedule, and potential conflicts should be addressed per group guidelines. Contact instructor if issues arise.

The rising insurance premiums in the Northeastern United States compared to the Midwest have sparked considerable debate. While insurance companies attribute this discrepancy to riskier lifestyles prevalent in the Northeast—such as higher rates of smoking, binge drinking, or sedentary behavior—such claims merit rigorous analysis supported by empirical data. To investigate these assertions, a comprehensive statistical examination of behavioral, economic, and environmental factors was undertaken, primarily leveraging data from the 2010 CDC Behavioral Risk Factor Surveillance Survey, U.S. Census data, and online cost of living calculators.

The initial step involved accurately delineating which states comprise the Northeast versus the Midwest, based on official federal definitions using the CDC PDF map reference. This classification enabled the segmentation of data for comparative analysis. The second step focused on collating and weighting survey results, applying population estimates from the 2000 census to produce representative aggregate behavioral percentages for each region. This approach addressed the disparity between survey sample sizes and actual regional populations, ensuring more precise regional estimates.

Following data preparation, hypothesis testing was conducted to evaluate whether observed differences in risky behaviors—such as binge drinking rates or smoking prevalence—were statistically significant. Confidence intervals were built around the difference in means and proportions between regions, utilizing standard error calculations and t-distribution or z-distribution techniques as appropriate. For example, the analysis revealed that the percentage of binge drinkers was higher in the Northeast; however, the confidence interval analysis determined whether this difference was statistically meaningful or could be attributed to sampling variability.

Beyond behavioral data, we incorporated census information on median income and education levels, specifically the percentage of the population with bachelor’s degrees. Correlation analyses were performed to examine relationships between these socioeconomic factors and risky health behaviors. Results indicated inverse relationships: higher income and education levels were associated with lower rates of smoking and binge drinking. These findings align with existing literature suggesting that socioeconomic status influences health behaviors and outcomes.

Such findings were corroborated by recent research, including Harvard studies, demonstrating that wealthier populations tend to live longer, partly due to healthier lifestyles and better access to healthcare. For instance, a Harvard study (Chetty et al., 2016) found significant correlation between socioeconomic status, longevity, and overall health, emphasizing that wealthier individuals often engage less in risky behaviors and enjoy healthier lives.

The analysis then addressed the hypothesis that higher insurance premiums in the Northeast are merely reflective of higher living costs. Using online cost of living calculators such as Money Magazine’s Cost of Living Calculator, data confirmed that the Northeast has substantially higher costs for housing, transportation, and healthcare compared to the Midwest. This economic disparity explains, at least in part, the elevated insurance premiums—insurance companies often pass these higher costs on consumers.

Integrating behavioral, economic, and cost-of-living data provided a comprehensive view: elevated premiums are influenced by actual higher costs of living, rather than solely by riskier lifestyles. While behavioral differences do exist between regions, their magnitude and significance are insufficient alone to justify the premium disparities. Instead, economic factors—cost of housing, healthcare, and general living expenses—play a dominant role.

In conclusion, the regional differences in insurance premiums are primarily driven by the higher cost of living in the Northeast, not solely by riskier health behaviors. Although certain behavioral factors are more prevalent in the Northeast, their impact on insurance costs is comparatively minor relative to economic disparities. Policymakers and insurers should consider these nuanced findings to implement more equitable pricing models. This study underscores the importance of considering socioeconomic and environmental variables alongside health behaviors when evaluating regional insurance differences.
