The typical American family has long been described as "nuclear," consisting of one father, one mother, and children. But according to a new study from FlowingData’s Nathan Yau, the nuclear family is just barely still the dominant structure reports Fast Company writer Charlie Sorrel.

The nuclear family wins, barely, accounting for 54% of households. But the most interesting part might be that other 46%, the non-nuclear families. Nuclear is defined by the UN as any of the following: "a married-couple family, with or without child(ren), or a father (or mother) with child(ren)."
