[The hidden family]

"Dutch society witnesses a continuous growth in the number of both singles and cohabitors. Despite this fact most young people indicate that they eventually desire to marry and to have children.... When cohabitation is not recorded or registered in a uniform manner, statistics which consider only married couples with or without children as families underestimate the de facto number of families. If both married and unmarried couples are considered as family nuclei, as recommended by the United Nations, the total formal number of families in the Netherlands has to be augmented with approximately half a million ¿hidden' families consisting of unmarried couples."
