Being evicted can have a significant impact on a person's health, according to new research.
In U.S. counties where eviction rates were elevated, death rates were higher for all causes, especially if those areas were home to a higher proportion of Black residents and women.
U.S. communities with higher Hispanic, American Indian or Black populations also have the highest concentrations of metal in public water systems, new research reveals.
