Between May 2020 and December 2021, there were 159,872 drug overdose deaths in the US. Higher eviction rates have been associated with higher overdose mortality. Amid the economic turmoil caused by the COVID-19 pandemic, 43 states and Washington, DC, implemented eviction moratoria of varying durations. These moratoria reduced eviction filing rates, but their impact on fatal drug overdoses remains unexplored. We evaluated the effect of these policies on county-level overdose death rates by focusing on the dates the state eviction moratoria were lifted. We obtained mortality data from NCHS and eviction moratoria dates from the COVID-19 US State Policy Database. We employed a longitudinal targeted minimum-loss-based estimation with Super Learner to flexibly estimate the average treatment effect (ATE) of never lifting the moratoria. Lifting state eviction moratoria was associated with a 0.14 per 100,000 higher rate of monthly overdose mortality (95%CI: -0.03, 0.32), although confidence intervals were wide and included zero. Eviction moratoria may not be sufficient to prevent overdose mortality during crises such as the COVID-19 pandemic.

Housing insecurity is a key social determinant of a wide range of health outcomes, subject to large racial inequities, and with a likely sensitive period in childhood. Housing insecurity can manifest in multiple ways and change over time, but previous studies have primarily focused on single dimensions or a single time point. This study examines cumulative exposure to multiple forms of housing insecurity from birth to adolescence, overall, and by race in large US cities. Using data from the Future of Families and Child Wellbeing Study (FFCWS), we estimated cumulative incidence and mean cumulative count of several forms of housing insecurity, accounting for missing data (due primarily to gaps between waves) using lower bounds and a mixed modeling approach. Between 45% (lower bound) and 71% (modeled) of children experienced at least one housing insecurity event by age 15. The average number of events among children who had any event was between 2.63 (lower bound) and 6.11 (modeled). Children of non-Hispanic Black and Hispanic mothers, compared to non-Hispanic White mothers, were more likely to experience an initial event, but once experienced, had similar numbers of events. We find a massive and cyclical burden of housing insecurity during childhood. Large racial differences in incidence of first events, but not repeated events, suggest that preventive interventions would most effectively mitigate racial inequities in housing insecurity.

The number and percentage of people in the US dying while homeless has increased in recent years. However, information about the causes of death most prevalent among this population, and about how cause-specific mortality rates may be shifting over time, has been limited to locally specific data. Using a unique data set of 22,143 homeless decedents in twenty-two localities across ten states and Washington, D.C., from the period 2011-20, we found large increases in all-cause and cause-specific homeless mortality rates. The largest increases in cause-specific homeless mortality rates in the ten-year period were for deaths related to drug and alcohol overdose, diabetes, infection, cancer, homicide, and traffic injury. We discuss implications of these results and posit that people experiencing homelessness are systematically excluded from the life-affirming institutions of housing and health care, in an example of mortal systemic exclusion. The findings have important implications for existing local and federal policy approaches to homelessness.

Housing insecurity can take multiple forms, such as unaffordability, crowding, forced moves, multiple moves, and homelessness. Existing research has linked homelessness to increased emergency department (ED) use, but gaps remain in understanding the relationship between different types of housing insecurity and ED use. In this study, we examined the association between different types of housing insecurity, including detailed measures of homelessness, and future ED use among a cohort of patients initially seen in an urban safety-net hospital ED in the United States between November 2016 and January 2018. We found that homelessness was associated with a higher mean number of ED visits in the year post-baseline. Other measures of housing insecurity (unaffordability, crowding, forced moves, and multiple moves) were not associated with greater ED use in the year post-baseline in multivariable models. We also found that only specific types of homelessness, primarily unsheltered homelessness, were associated with increased ED use.
