Data Source and Accuracy: All data is currently sourced from the National Fire Incident Reporting System (NFIRS). Once the National Emergency Response Information System (NERIS) releases its public version, "NERIS Public," we will transition to using it. We only manipulate data when calculating averages for state and county metrics (such as clear times, scene times, and response times). In these cases, we may remove outliers to prevent a single data point from skewing the overall results. Otherwise, we report the data directly from the NFIRS public database. We will label this on each section for transparency.
