Skyrocketing health insurance premiums have sparked a 10-year decline in employer-sponsored health insurance nationwide, including Oklahoma, an analysis published Wednesday by the Robert Wood Johnson Foundation shows.

In the state, 32.3 percent of smaller firms offer insurance, down from 37.4 percent, while 94.3 percent of firms that employ 50 or more offer plans, down from 96.6 percent.
Researchers found Michigan experienced the deepest drop in employer-sponsored coverage in the period: 5.2 percentage points. North Dakota's slipped less than 1 point.

Family premiums nationwide rose 125 percent, from $6,415 to $14,447. In Oklahoma, the employee share of family coverage rose from $1,689 to $4,081.
