In contrast, when we hold constant the ratio of per capita health
expenditures to income, there is very little change in coverage over
the period (Exhibit 3). For example, among workers for whom per
capita health spending is between 5 and 10 percent of their income,
approximately 14 percent are uninsured, and this figure does not
vary much from 1979 to 1995. As the expenditure-to-income ratio
rises, the likelihood of coverage falls, but at any given expenditureto
income level the probability of coverage in 1992–1995 is similar to
the probability in 1979–1983.
