In this study, we aim to reveal hidden patterns and confounders associated with policy implementation and adherence by investigating the home‐dwelling stages from a data‐driven perspective via Bayesian inference with weakly informative priors and by examining how home‐dwelling stages in the USA varied geographically, using fine‐grained, spatial‐explicit home‐dwelling time records from a multi‐scale perspective. At the U.S. national level, two changepoints are identified, with the former corresponding to March 22, 2020 (9 days after the White House declared the National Emergency on March 13) and the latter corresponding to May 17, 2020. Inspections at U.S. state and county level reveal notable spatial disparity in home‐dwelling stage‐related variables. A pilot study in the Atlanta Metropolitan area at the Census Tract level reveals that the self‐quarantine duration and increase in home‐dwelling time are …
