An au pair (plural: au pairs) is a domestic assistant from a foreign country working for, and living as part of, a host family. Typically, au pairs take on a share of the family’s responsibility for childcare as well as some housework, and receive a monetary allowance for personal use. Au pair arrangements are subject to government restrictions which specify an age range usually from mid-late teens to mid to late twenties; some countries explicitly limit the arrangement to females.
Arrangements differ between Europe, where the concept originated, and North America. In Europe, au pairs are only supposed to work part-time, and they often also study part-time, generally focusing on the language of the host country. In the United States, they may provide full-time childcare. In 1969, the European Agreement on Au Pair Placement was signed, and it came into force in 1971.
