This is considered a  reliable resource for establishing if a child is going through post traumatic stress disorder due to physical, sexual, or mental abuse.In a study conducted in Oregon and Washington state, the rate of PTSD in adults who were in foster care for one year between the ages of 14–18 was found to be higher than that of combat veterans, with 25 percent of those in the study meeting the diagnostic criteria as compared to 12–13 percent of Iraq war veterans and 15 percent of Vietnam war veterans, and a rate of 4% in the general population. The recovery rate for foster home alumni was 28.2% as opposed to 47% in the general population. "More than half the study participants reported clinical levels of mental illness, compared to less than a quarter of the general population". Eating disorders
Foster children are at increased risk for a variety of eating disorders in comparison to the general population. In a study done in the United Kingdom, 35% of foster children experienced an increase in Body Mass Index (BMI) once in care. Food Maintenance Syndrome is characterized by a set of aberrant eating behaviors of children in foster care. It is "a pattern of excessive eating and food acquisition and maintenance behaviors without concurrent obesity"; it resembles "the behavioral correlates of Hyperphagic Short Stature". It is hypothesized that this syndrome is triggered by the stress and maltreatment foster children are subjected to, it was prevalent amongst 25 percent of the study group in New Zealand.
Census data from 2011 counted children in foster care for the first time, counting 47,885 children in care. The majority of foster children – 29,590, or about 62 per cent – were aged 14 and under. The wards remain under the care of the government until they "age out of care." All ties are severed from the government and there is no longer any legal responsibility toward the youth. This age is different depending on the province. Israel
In December 2013, the Israeli Knesset approved a bill co-drafted by the Israel National Council for the Child to regulate the rights and obligations of participants in the foster care system in Israel. Japan
The idea of foster care or taking in abandoned children actually came about around 1392-1490s in Japan. The foster care system in Japan is similar to the Orphan Trains because Brace thought the children would be better off on farms. The people in Japan thought the children would do better on farms rather than living in the "dusty city." The families would often send their children to a farm family outside the village and only keep their oldest son. The farm families served as the foster parents and they were financially rewarded for taking in the younger siblings. "It was considered an honor to be chosen as foster parents, and selection greatly depended on the familys reputation and status within the village".
