More than thirty million housing units in the United States present significant physical, health, and developmental hazards — with a significant number of those unite concentrated in high-poverty neighborhoods, a report from the Center for American Progress finds. The report, Creating Safe and Healthy Living Environments for Low-Income Families (24 pages, PDF), found that children exposed to lead poisoning are seven times more likely than other children to drop out of school and six times more likely to become involved in the juvenile justice system; that mold, dust mites, and other hazards are estimated to be the cause of 40 percent of asthma episodes; and that neighborhood violence can negatively affect children's behavior and academic performance and/or cause post-traumatic stress disorder. The report also found that the 20 percent of Americans with a disability face a range of barriers to affordable housing, including discrimination and a lack of accessibility features in public housing. Recommendations for creating safe and healthy living environments for low-income families include boosting funding support for lead poisoning prevention, the federal housing voucher program, and affordable rental housing; incorporating a focus on health in place-based initiatives; and investing in community-based violence-reduction programs.
