licensed prepaid health service organizations, 5 Health Flex Plans and 38 Discount Medical Plans. There are 21 domestic
insurers, and 488 foreign insurers.
 
The analysis shows that Florida ranks behind only New York and California in the amount of health insurance written. In 2005, the combined premiums for health insurers (along with life and health and accident) totaled $45.5 billion, the OIR analysis indicates. In all, more than $80.9 billion in premiums across all lines of insurance was collected in 2005.

Florida's Uninsured Population is on the Rise 

The percent of uninsured citizens in the state of  Florida, meanwhile, is on the rise.  The exact percent of residents without insurance can be debated but most estimates rank Florida either second or third in the percent of residents without health insurance.

United States Census Bureau estimates indicate that in 2005 (latest available figures) more than 3.4 million Floridians were without  health insurance sometime throughout the year, which translates to about 20 % of the population. The other 80 % of Floridians were covered either through private plans or through government programs. That’s a 2.6 % dip from the number of insured citizens in  2002.
