Veterans Homelessness Veterans experience multiple challenges during tour of duty (service) and upon their return, which present obstacles when trying to tackle veteran homelessness. Amongst veterans there are high rates of post-traumatic stress disorder (PTSD), traumatic brain injury, and sexual trauma, which can lead to higher risks of homelessness. Additionally, many veterans are considered at risk of homelessness because of poverty, lack of support from family and friends, substance use or mental health issues, and precarious living conditions. Another recent survey conducted by the Iraq and Afghanistan Veterans Association (IAVA) found that an incredible 59 percent of those surveyed knew another vet who’d tried to kill themselves, and 58 percent knew at least one who’d succeeded. Not surprising given that, according to estimates, as many as 24 veterans take their lives every day.
