1.2 Family Relationships (Relaciones familiares)

La familia extendida (the extended family) often plays a big part in daily life. In many families grandparents look after grandchildren while both parents work, and Sunday lunch with relatives is a weekly ritual for many. Research on Latino families sometimes calls this strong family loyalty familismo. Still, avoid treating it as the same everywhere: a family in Madrid, one in rural Guatemala and one in Buenos Aires live very differently.

Godparents matter too. Parents choose los padrinos (el padrino, the godfather, and la madrina, the godmother) at a baby's baptism, and they're expected to support the child for life. The parents and godparents call each other compadre and comadre, a bond called el compadrazgo. In Mexico, padrinos also sponsor parts of a quinceañera or a wedding, such as the cake or the music.

In most Spanish-speaking countries people carry two surnames (los apellidos). Traditionally the first is the father's first surname and the second is the mother's first surname. Gabriel García Márquez got García from his father and Márquez from his mother, so he's “García Márquez” or “García,” not “Márquez.” Libraries alphabetize him under G.

In Spain and most of Latin America, women usually keep their own surnames when they marry. The older custom of adding “de” plus the husband's surname is now rare in most places. Since 1999, Spain has let parents put the mother's surname first, as long as all their children share the same order, and several Latin American countries have made similar changes.

Families are getting smaller. Spain and many Latin American countries, including Chile, Argentina, Colombia and Mexico, now have fertility rates below 2.1 children per woman, the level needed to keep a population steady. Common reasons include the cost of raising children, more women in universities and careers, later marriage and expensive housing.

Young adults also leave home later. Eurostat found that in 2025 young people in Spain left their parents' home at 30.2 years on average, compared with 26.3 across the European Union. High rents and unstable, temporary jobs are the main reasons. La emancipación is the word for moving out and becoming independent.

The law now recognizes more kinds of families. Spain legalized same-sex marriage in 2005, one of the first countries in the world to do so, and Argentina did the same in 2010, the first in Latin America. You'll also read about single-parent families (las familias monoparentales) and blended families (las familias reconstituidas, or ensambladas in Argentina).

Family topics often come with a chart. Learn the words for trends: aumentar, crecer or subir (to rise), disminuir, bajar or caer (to fall), mantenerse estable (to stay steady), la tendencia (the trend), la tasa (the rate), la tasa de natalidad (the birth rate), la tasa de fecundidad (the fertility rate, children per woman), el promedio or la media (the average), la mitad (half), un tercio (a third) and el doble (double).

Watch the number format. Spain and much of South America use a comma for decimals and a period for thousands, so 30,4 % means 30.4% and 1.500 means 1,500. Mexico and Central America mostly use the same format as the US. Also, un billón is a trillion; a billion is mil millones.
