Premiums for employer-sponsored family health insurance increased by 50 percent from 2003 to 2010, and the annual amount that employees pay toward their insurance increased by 63 percent as businesses required employees to contribute a greater share, according to a new Commonwealth Fund report.

Health insurance costs are outpacing income growth in every state in the country, the report finds. And at the same time, premiums are buying less protective coverage: per-person deductibles doubled for employees working for large as well as small firms over the same time period.

The report says by 2010, 62 percent of the U.S. population lived in a state where health insurance premiums equaled 20 percent or more of earnings for a middle-income individual under age 65. Today there are virtually no states where premiums are relatively low compared to income. In 2003, there were 13 states where annual premiums constituted less than 14 percent of the median (middle) income. By 2010, there were none.
