3 3 Presentation Overview 2004 vs surveys conducted in Oklahoma The uninsured in Oklahoma Health insurance coverage in Oklahoma As time permits and if there is interest, more information on how the 2008 survey was conducted

4 4 Background New telephone survey conducted in 2008; prior survey conducted in 2004 Purpose of new survey is to update data for the state and assess changes over time All data are based on point-in-time estimates of health insurance coverage and type Results are for randomly-selected household member Data are weighted to represent Oklahoma population –Note: 2004 data were reweighted to be comparable with 2008 weights –Estimates for 2004 vary slightly from 2004 final report

5 Sample Size5,8475,729 Sampling StrategyRDD (landline only) 3 strata based on geography RDD (landline only) 3 strata based on race/ethnicity Slight oversamples of African-Americans and American Indians Questionnaire Length/Languages Averaged 15 minutes/ English & Spanish Averaged 15 minutes/ English & Spanish Questionnaire Content Health insurance status Access to health care Public program awareness Cost concerns Demographics Generally the same Some additions/deletions Revised items re: income Time of Year Conducted March – MayJuly – September Response Rate (AAPOR RR4) 44.4%15.6% & 2008 OK Survey Comparison

6 6 Response Rate Insights We anticipated a drop in response rate –Rates are falling for all types of surveys (RDD, mail, in-person, federal and state) Factors contributing to reduced response rates –Growth in non-contact rate (e.g., screening devices) –Growth in refusals –Other potential factors Lower response rates among minority groups (which we slightly oversampled) Response rates and survey quality

27 27 Summary of Key Findings to Date: Health Insurance Coverage 16.7% of Oklahoma residents, or about 579,036 individuals (including all age groups), uninsured in 2008 Higher uninsurance rates: Young adults (19-34 year olds), Hispanics, American Indians, not in labor force, low income (especially for adults) Overall uninsurance rate was stable between 2004 & 2008 –Increase in public health insurance coverage –Decline in employer-based health insurance –These trends consistent with Current Population Survey data for OK and US A few changes in uninsurance rate between the 2 years: –Decline among near elderly (55-64 years) –Decline among Whites –Decline in Southeast region

28 Summary of Key Findings to Date: Employer-Based Coverage The overall rate of employer-based (group) coverage dropped from 51.5% of Oklahoma’s total population in 2004 to 45.1% in 2008 Group coverage more prevalent among: –Middle-aged and older non-elderly adults –Whites –Employed –Higher income –Northwest region Decline in employer-based coverage between 2004 & 2008 impacted: –Both males and females –Most adult age groups (25-54 year olds and the elderly) –All racial/ethnic groups except for Hispanics and Asians –Both the employed and unemployed –Central, Northeast, and Tulsa regions 28

29 Summary of Key Findings to Date: Public Coverage The overall rate of public coverage grew from 25.8% of Oklahoma’s total population in 2004 to 33.3% in 2008 Public coverage more prevalent among: –Young children and the elderly –African-Americans and American Indians –Not employed –Low income (especially for children) –Southeast region Growth in public coverage between 2004 & 2008 impacted: –Both males and females –Most age groups (except for young children and young adults aged 19-34) –Whites and American Indians –Both the employed and unemployed –All regions but the Northwest and Southwest

30 Summary of Key Findings to Date: Possible Explanations In 2008, fewer Oklahomans may have access to employer-based coverage: –Increase in self-employed (12% vs. 16%) –Fewer working in large firms of 500 employees or more (44% vs. 38%) In 2008, more Oklahomans are potentially eligible for public coverage: –Increase in percent below 100% FPL (18% vs. 22%) –Increase in percent unemployed (28% vs. 32%)

31 31 SHADAC’s Next Steps Proceed with analyses of 2008 survey data and comparisons with 2004 Conduct small area estimation to estimate rates of uninsurance at the county level More reports and information to come: Final report on 2008 survey including technical appendix on survey methodology County-level chartbook
