Nationally, children are often homeless because they run away from violence in their home or they’ve aged out of the foster-care system. In Silicon Valley’s case, the problem is the cost of living, The Guardian reports. A full 1,147 children are defined as homeless. Many of them end up mostly sharing homes with friends or family members because their parents can’t afford housing. Others live in RVs and shelters.

The most recent national data, from 2013 outlines a record level of homelessness for 2.5 million children, while another 15 million children live in poverty, according to the National Center for Children in Poverty and the American Institute of Research. That’s more than 1 in 5 children in the United States who go to bed hungry, don’t have clean clothes for school or struggle to find a place to sleep — despite record levels stock market.
