|Description:||The Washington State Population Survey (WSPS) is a source of information about the health and welfare of Washington families. The survey focuses primarily on issues of employment, family poverty, migration into the state, health, and health insurance coverage.|
|Relevant Policy Issues:||Measurement of Health Status, Factors Contributing to Measured Health Disparities, Income Status, Unemployment Rates, Economic Assistance Program Participation Rates, and Economic Opportunity.|
|Unit of Analysis:||Individual|
|Identification of AI/AN/NA:||Instructions for reporting race are as follows: What racial group or groups best describes you?
Respondents could select more than one race.
|AI/AN/NA Population in Data Set:||The 2004 WSPS gathered data on 17,788 individuals from 7,097 households.
The unweighted counts for AI/AN respondents to the 2004 WSPS are as follows:
Unweighted counts of NH/PI respondents for the 2004 WSPS are as follows:
|Geographic Scope:||The geographic scope of the study is the state of Washington. Geographic areas are identified by regions of the state (e.g., North Puget, West Balance, King, Other Puget Metro, Clark, East Balance, Spokane, Tri-cities). The level of geographical analysis possible is state-wide or regional. However, regional analysis is not recommended for AI/AN/NA subgroups because of very small sample sizes.|
|Date or Frequency:||The WSPS has been conducted biennially since 1998. The 2006 administration of the survey was underway at the time of preparation of this catalog.|
|Data Collection Methodology:||The WSPS is a telephone survey.|
|Participation:||Optional, without incentives|
|Response Rate:||WSPS survey contacts indicated that the response rate for the 2004 study was low.|
|Sampling Methodology:||For the WSPS, a stratified sample by region was selected from all households in state of Washington with an activated telephone line, either listed or unlisted. A target of 750 households was planned for each of the eight regions with the exception of King County where a target of 1,800 households was planned. More households were selected in King County to insure sufficient information on racial minority groups for statistical analyses. Households were selected in each of the regions using random digit dialing (RDD) technique.|
|Analysis:||There are two weights for use in analysis. A population weight is available that weights the survey responses to represent the state population based on Census Bureau population counts. There is also a weight based on administrative records for Medicaid that, when used, will yield improved estimates for uninsured persons.|
|Strengths:||Data are collected on key policy issues including health and economic status. There are multiple years of data available.|
|Limitations:||There are limited AI/AN/NA respondents in this data source. This study has a low response rate.|
|Access Requirements and Use Restrictions:||Data are available to the public at no cost.|
