From the House Committee on Health Innovation, analysis of HB 71, January 22, 2008. 

The average cost of health insurance in the United States has increased by 87 percent since 2000. In 2006, premiums for family coverage increased 7.7 percent nationally. This is less than the 9.2 percent increase for 2005, but exceeds the overall inflation rate, which was 3.5 percent, and the increase in workers’ earnings, which was 3.8 percent.

The average premium cost of single coverage for covered workers in 2006 is on average $354 per month or $4,242 per year, while the average cost of family coverage is $957 per month or $11,480 a year. Premiums further vary based on the type of policy workers are covered under. Preferred Provider Organizations plans have the highest enrollment and face higher average premiums for both single and family coverage than Health Maintenance Organizations, Point of Service, and High Deductible Health Plans with Savings Options plans.

From the Senate Banking & Insurance Committee, February 28, 2008, analysis of SB 164:

In Florida, the average cost of family coverage (for health insurance) is about $1,000 a month, or $12,000 a year.
