Regression Results from the Callawy and Sant'Anna difference-in-differences (CSDID) approach, with a universal base period. Using 2020 standardized Census tracts which maintained consistent treatment assignment from 2010 to 2020 boundary definitions. The results include conditional parallel trends accounting for the tract's poverty rate, median household income, and the share of a tract's housing stock that are defined as solo and detached in the fourth quarter of 2017. The comparison group are defined using a doubly-robust estimator selecting from all US census tracts in sample.
