The data presented here was compiled from maps published by the SPD that present adult drug arrests in 1999 by census tract for “All Races, White, Black, Asian, and Native American.”*

These estimates are approximations. Census tracts do not fall perfectly within the confines of precinct boundaries. For purposes of this analysis, census tract 82 (34 arrests) was included in the East Precinct (and not the West Precinct). Census tract 91 (92 arrests) was considered in the East Precinct (and not the West Precinct). Census tract 93 (38 arrests) was con- sidered in the West Precinct (and not the South Precinct). Additionally, the

total adult narcotics arrests on these maps sum to 3018. The total narcotics arrests reported in the SPD 1999 Annual Report was 3872.**

King County Profile of Substance Use and Need for Treatment Services in King County, Washington State Department of Social and Health Services, Division of Alcohol and Substance Abuse, Research and Data Analysis, December 1999.

“The purpose of this report is to provide local planners and evaluators with information that can be used to compare need for and utilization of

substance abuse services in counties and demographic subpopulations. The methods used for the county profiles update and improve upon the analyses presented in the first set of county profiles published in 1996.”75

The Washington Needs Assessment Household Survey (WANAHS)

“The WANAHS was a statewide survey of over 7,000 adults designed to measure the prevalence of substance abuse and need for treatment. It was conducted over a 14-month period from September 1993 through October 1994. . . . The WANAHS sample included approximately equal numbers of interviews with African Americans, Asians, Hispanics, American Indians, and Non-Hispanic Whites. Additional samples of people living at or below 200% of the Federal Poverty Level (FPL), rural residents, and women were interviewed adding coverage of important, but sometimes overlooked, populations. . . . The survey instrument had questions about current and past use of or dependence on major drugs of abuse. . . . Upon weighting the WANAHS sample to match the actual population distribution, the survey provides direct statewide estimates of substance abuse as well as the need for substance abuse services.”76

Methods for Estimating County-Level Prevalence Rates

“In order to derive current county level estimates for substance abuse and need for treatment from the statewide survey, it was necessary to construct a demographically specified population matrix for each county against which the state-wide survey based rates could be applied. The population matrix contained counts of persons in all groups defined by age, sex, race, marital status, high school graduation, poverty status (at or below 200% Federal Poverty Level) and residence type. The population groups were developed from 1990 U.S. decennial census data and updated with current estimates of age, sex and race from DSHS. All annual estimated and forecasted popu- lation figures are adjusted to match official Washington State population figures from the Office of Financial Management.”77

“The substance use variables from the WANAHS were analyzed by the demographic variables listed above. Logistic regression models estimated rates for each cell in the demographic matrix. Differences between counties in estimated rates of substance abuse result from the demographics of the county. For example, counties with higher proportion of young adults will have higher rates of current substance abuse than counties with lower proportions of young adults, because young adults are more likely to be using substances. Similarly, since married persons are less likely to report substance use, a county with more married people will have a lower estimate of need.”78

Estimates for entire adult population:

“Entire adult population (age 18+) including those living in households, institutions (prisons, hospitals and nursing homes) and group quarters (military barracks, college dorms, shelters). Residential settings defined according to the U.S. Bureau of Census definition. The estimates for the population are based on the WANAHS survey rates, except that for the insti- tutional population, particularly those in prison the rates in the WANAHS survey have been inflated beyond the rates for corresponding demographic cells in the household population to compensate for higher rates in these institutional populations.”79
