For months, we have been collecting COVID-19 data, scrutinizing publicly available data definitions, and engaging in frequent conversations with jurisdictions to understand the data they share.
During this process, we have focused on three aspects of COVID-19 data reporting: 1) how the state defines and reports key metrics, such as testing data, cases, hospitalizations, and deaths, 2) how the state presents information about COVID-19 in long-term-care facilities, and 3) how the state reports race and ethnicity data.
Our assessment below reflects both the thoroughness of Wisconsin’s reporting and the completeness and clarity of their data descriptions. We hope this work will not only help our data users to better grasp the limitations of these numbers but also might help health officials to understand the differences in data reporting across jurisdictions.
We require data definitions to be accessible from a state’s data pages and presented in a location where it is clear they will be maintained. Examples include data definition documents, data FAQs, dashboard footnotes, or definitions appearing daily in press releases.
