^a All 500 participants reported gender, race, age, and stratum, 463 reported health insurance status.* ISF different than NF (2-sided T-test, alpha = 0.05), ** CFS different than non-CFS (ISF+NF) (2-sided T-test, alpha = 0.05). All estimates weighted to reflect sampling probabilities. †Computed by multiplying reported 4-week earnings by 13.
