Officials in central Ohio are trying to figure out why the rate of family homelessness in the area is rising despite a nationwide decline. Figures released last month by the U.S. Department of Housing and Urban Development showed the number of homeless families across the country had decreased by 15 percent since 2010. But estimates show family homelessness in the Columbus area increased by 7.6 percent during that time. Analysts say the well-known family shelter system in Columbus could attract a larger number of families seeking help. Other factors for homelessness include low-wage jobs, a lack of affordable housing, cuts to welfare and mental illness and addiction. Officials say they plan to research local homeless families and the system currently in place to help them.
