The One Night Count: People Who Are Homeless in King County

Sustainability Snapshot:

Homelessness has become part and parcel of our local and national landscapes to the extent that many consider it a given. The lack of affordable housing in a region is a key factor in increasing homelessness, together with many other socioeconomic issues. As Steven V. Sundborg, SJ, President of Seattle University and Board Member of the Committee to End Homelessness, remarks, “It tells us if our educational system is working, our criminal justice system is working, our physical and mental health systems are working, and whether we are providing our community members with the support and services they need.”

Sustainability Trend:

From 2000 to 2004, the number of homeless increased nearly 30% to 6,852. On the one night count for 2008, that number had risen to 8,439, an 8% increase over 2007 figures. (Survey methods were changed in 2006.) Of these, nearly one third, including children, were sleeping outside in below freezing weather, an increase of 15% over the previous year. (1) The current emergency system and transitional housing system has approximately 6,700 beds. (2)

Data Discussion

The Indicator Defined

Estimated homeless population in King County.

Data Interpretation/Evaluation

Between 2000 and 2004, the estimated homeless population in King County increased nearly 30%, ten times the rate of population growth experienced by the county as a whole. Estimates suggest that over 8,300 people in King County were homeless on a typical night in 2004, or 0.47% of the county population. The Seattle-King County One Night Count (ONC) is a tally of unsheltered persons and a survey of the sheltered homeless community. In January 2006, ONC counted 1,946 persons on the street and surveyed another 5,964 in emergency and transitional housing. About 83% of the 1,946 unsheltered homeless persons were in Seattle. Almost one-third of the homeless sheltered persons were children under the age of 18.
