This interactive map provides estimates of the percent of individuals who report having disaster supplies set aside in their home, based on 2015 national survey data. Estimates are available at the state level and the metropolitan/micropolitan area level.

Estimates and margins of error are derived from a multilevel regression and poststratification (MRP) model based on national surveys of U.S. adults (18+) conducted from April through November 2015 (n=11,260). Margins of error represent 95% prediction intervals. Estimates were validated against separate state-level surveys and American Housing Survey data for selected metropolitan areas. Data collection for this study was supported by a grant from the Utah State University Office of Research and Graduate Studies.
