More than 4 in 10 (41%) French Polynesians live in complex households, the majority sharing a home with several generations of the same family, and a minority coresiding with peers. These households include a large share of young adults and people facing economic insecurity due to a lower-than-average level of education and a higher risk of unemployment. Dwellings occupied by complex households have amenities of similar quality to those of nuclear family households. Coresidence with extended family remains common in this highly urbanized society, providing protection against economic insecurity.
