Beginning in 1980, the international community increased its attention to problems related to families. The UN General Assembly was adopting resolutions in this regard, seeking to increase the awareness of the States and civil society about the problems and needs of the families, as well as to achieve effective tools to meet those needs.

Among other decisions, in 1989 the General Assembly proclaimed 1994 as the International Year of the Family, and in 1993 decided that on May 15 of each year the International Day of Families be celebrated. Finally, in 2012 the UN proclaimed June 1 as Global Parents Day, “to be observed annually in honor of mothers and fathers throughout the world.”

In recent decades, the concept of traditional family in many countries has evolved towards another in which love is equally important and that re-signifies the possibility of being a mother or father also in family structures formed not in a heteronormative way. Although the advance of all these rights in the world is very uneven and in many countries the old stereotype is still maintained, in other countries and regions the concept of a diverse family has prevailed, which does not include only same-sex couples and their children, but also transgender people and heterosexual marriages with homosexual, bisexual or transgender children. In addition, and although the concept is commonly used to refer to LGBT families, other types of family structures can be perfectly included under the “diverse” category, including single biological mothers or fathers, foster mothers or fathers (or legal guardians), adoptive mothers or fathers, married, united or single, or polyamorous parents (multiple romantic partners in the home).
