Homelessness has a profound and often lasting impact on the emotional and physical health of children—starting from day one. Homelessness is linked in children to low birth weight, malnutrition, ear infections, exposure to environmental toxins, and chronic illnesses such as asthma. One in five homeless preschoolers have emotional problems that require professional care and 54 percent of homeless preschoolers experience a major developmental delay. Homeless elementary school students score lower on reading and math achievement tests compared to low-income housed students; and half of school-age homeless children experience problems with depression and anxiety. Homeless students are twice as likely to repeat a grade or be suspended from school. The list, unfortunately, goes on.
