Household size and composition The average household size has decreased statewide over the past five decades. In Oregon, the average household size was 2.60 in 1980, 2.52 in 1990, 2.51 in 2000 and 2.47 in 2010. Households with three or more people accounted for 39% of households in 1990, decreasing to 35% in 2011. Even if the population were not growing, the impact of decreasing household size on housing demand is that there will be more households, which translates to a need for more housing units. Table 13 shows average household size in Oregon, Lane County, and Eugene for 2000 and 2010. Table 13 shows that the 2000 Census estimated that Eugene had 2.27 persons per household. The 2010 American Community Survey estimated that household size decreased to 2.24 persons per household. This decrease in household size (by about 0.03 persons per household) is consistent with County and State trends. Table 13.
