The term Kinderlandverschickung (KLV) was used from the late 19th century for Erholungsverschickung ("recreational deportation") of sick and underprivileged children to foster care in the country.[1] From 1916, the Reichszentrale Landaufenthalt für Stadtkinder (Reich Central Office Country Residence for City Children) coordinated country holidays for city children, usually of around ten to fourteen years of age for a duration of up to three weeks. Around 488,000 children were sent in 1923 and 650,000 in 1934.
