Employee health insurance is on the decline, CNN Money reported.

For small businesses, it's gone from bad to worse.

The share of small companies providing medical coverage to employees fell to 38 percent in 2011, down from 47 percent in 2000, according to a report from the Robert Wood Johnson Foundation.

The proportion of all companies offering insurance fell from 59 percent to 52 percent.

Annual premiums paid by individuals doubled to $5,081 from $2,490, and family premiums rose from $6,415 to $14,447.

The study defined small businesses as those with fewer than 50 employees. The Robert Wood Johnson Foundation is a longtime supporter of health care reform.

In total, 11 million people lost insurance during an 11-year period. The number of people whose work provided insurance dropped from 170 million to 159 million. Read more.
