Demographic characteristic known from administrative data.

$$

Demographic characteristics known from self report.

(Note: Population number varies for each characteristic depending on the information available. The demographic data gathered from administrative files was more complete than the self-reported data.)

a

The employment status of the parent who completed the survey (>85% were mothers).

b

The insurance status of the parent who completed the survey.

c

Response to the following question: “Does YOUR CHILD have a physical, emotional, or mental health condition now that seriously interferes with your child’s ability to do the things most children his or her age can do?”

Column percentage=100% (may not be exact due to rounding to nearest 10th)

Total in sample with known administrative data and self-reported insurance information = (unweighted n=2,657, weighted n= 83,580).

Four groups: (1) Child Has Public Insurance (Oregon Health Plan—OHP) (enrolled in public insurance by both administrative data and self-report): unweighted n=1,300, weighted n= 57,356 (68.6%); (2) Child Has Private Insurance (private by self-report, not administratively enrolled in OHP): unweighted n=554, weighted n=9,211 (11.0%); (3) Child Has Uncertain Health Insurance Status “Gray Zone” (mismatch between administrative and self-reported data): unweighted n=423, weighted n=11,063 (13.2%); (4) Child Is Uninsured (uninsured by self-report, not administratively enrolled in OHP): unweighted n=380, weighted n=5,950 (7.1%).
