- In 1997-1998 a questionnaire was developed by the Office of the Medical Director, Ministry of Social Affairs and Social Services. This questionnaire has aimed to assess, on a yearly basis, the health of the residents with intellectual disability and the services provided to them by specific residential care centers within Israel. The present study was conducted to examine trends in the number of children with intellectual disability in residential care centers in Israel. We found a clear downward trend with regard to the percent of children living in residential care facilities, from 18.1% of the total population in 1999 to 13.3% in 2006. Children living in residential care in 2006 comprised 4.5% of the population of persons with intellectual disability serviced by the Ministry of Social Affairs and Social Services.
