Enrollee count is an estimate derived by evenly distributing the state's CMS plan-select total across counties; actual county enrollment varies with population.
How the Clay County estimate is calculated
Methodology: ACA Beacon does not have county-level enrollment dashboards for every U.S. county. To give you a directional sense of marketplace activity in Clay County, we take the most recent state-wide Open Enrollment Period (OEP) plan-selection total reported by CMSi (or the state-based marketplace) and divide it evenly by the number of counties in South Dakota.
Formula used here: 54,721 total state signupsi ÷ 66 South Dakota countiesi = ~829 estimated enrollees for Clay County.
Uncertainty & limitations: Counties vary widely in population, income, and insurer participation. Urban counties typically enroll far more residents than rural ones. This number is a simple average, not a forecast or official CMS county report. Use it as a rough indicator of statewide penetration, not a precise local count.
