Household Size by Race and Hispanic Origin, 2017

The average household in the United States is home to 2.54 people. But household size varies by race and Hispanic origin. Hispanics have the largest households and non-Hispanic Whites the smallest...

3.25 people in the average Hispanic household
2.90 people in the average Asian household
2.51 people in the average Black household
2.37 people in the average non-Hispanic White household

The younger age of the Hispanic population (median age = 29) explains their larger household size, with many Hispanics in the family formation years. The older age of the non-Hispanic White population (median age = 43) explains their smaller household size, with many non-Hispanic Whites in the empty-nest lifestage. Non-Hispanic Whites head 70 percent of the nation's single-person households and 74 percent of two-person households. But as household size increases, non-Hispanic Whites are a shrinking share of householders: they head 61 percent of three-person households, 60 percent of four-person households, 53 percent of five-person households, 47 percent of six-person households, and just 41 percent of households with seven or more people.
