* Relative standard error equal to or greater than 30%.

a Estimates are provided for 25 states and are listed in order of state population size. Reliable estimates can not be produced for the other states due to insufficient sample in those states.

b "Population" and "Percent with an expense" columns are based on "All persons". "Mean per person with an expense" and "Percent distribution of total expenses by source payments" columns are based on "Persons with an expense".

c The precision of an estimated standard error depends on the degrees of freedom available for estimating the standard error. In constructing a confidence interval for a state-level estimate, the corresponding degrees of freedom should be used in obtaining the critical value from the Student’s t-distribution.
