Note. Authors’ calculations using linked data from the Medical Expenditure Panel Survey (2005–2008), the 2000 Decennial Census, and the National Health Interview Survey (2004–2007). All decomposition models are estimated with controls for all variables listed in Table 2 and year dummies. The predisposing, enabling, and need factors do not sum up to the overall explained portion of the difference—the remainder is accounted for by the year dummies. Standard errors are in parentheses.

Significance level: *p < .10, **p < .05, ***p < .01.
