More than one-third of homeowners in our study had symptoms of major depression. The N.B.E.R. study found significantly more suicide attempts in high-foreclosure neighborhoods. For every 100 foreclosures, it found a 12 percent increase in anxiety-related emergency-room visits and hospitalizations by adults under 50. Losing a home disrupts social ties to neighbors, schools, jobs and health care providers — ties that under better circumstances promote good health. Neighborhoods suffer, not just homeowners.
