Arizona Population by Primary Insurance Market Segment, 2006 (In Thousands)

• Medicare enrollees account for 14% of the population, but approximately 30% of total healthcare expenditures.
• Within the non-Medicare population, employees of small businesses account for just 7% of the insured population, although small businesses represent approximately 90% of all Arizona businesses.
• 40% of Arizona's non-Medicare population is either uninsured or enrolled in AHCCCS.

Notes:

1. Medicaid figures do not include individuals who are also eligible for Medicare, as Medicare would be considered their "primary" source of health insurance coverage.
2. Small employers are those employers who employ 50 or fewer employers. Remaining employers are classified as "large employers."
3. Individuals covered only through the Indian Health Service are included in the uninsured market segment.
4. Due to rounding, numbers may not add to 100 percent.
