percentage of employers are using self insured group plans
Most Americans with employer-provided insurance are in self-funded plans, and that's been the case since at least 2010. Roughly 60% of members at Aetna, Anthem and Cigna are in ASO plans. More than 3 in 5 U.S. companies are self-insured, and self-insurance is almost universal among large employers. About 91% of people in companies with 5,000 or more workers were in self-insured plans in 2014, compared with 15% of people in companies with fewer than 200 workers, according to the Kaiser Family Foundation. Fifteen years ago, only 62% of workers in companies with 5,000 or more employees were in self-insured plans.
