Explanation Households have changed significantly in Thurston County over the last 50 years. In 1960, Thurston County averaged 3.1 people per household, and by 2010 this number had decreased to 2.5 people per household. This change can be attributed to a number of social trends including: an increasing tendency to postpone marriage, higher divorce rates, increasing numbers of one-parent families, an increase in the number of people choosing to live alone, and growing numbers of non-traditional households.

Within the Thurston County, Olympia and Tumwater had the smallest average household sizes, and the Nisqually and Chehalis Reservation, along with the City of Yelm, had the largest households.
