Nationally, family premiums for employer-sponsored health insurance increased 119 percent between 1999 and 2008, and they could increase another 94 percent to an average $23,842 per family by 2020 if the current pace of cost growth continues, according to new Commonwealth Fund analysis. The data brief finds that national reforms that slow health care cost increases by 1 to 1.5 percent per year would yield substantial savings for families and businesses across the country. In a new Commonwealth Fund Blog post, Fund President Karen Davis underscores the need for health reform legislation to lower premiums for employers and families by including a public plan or another effective option for controlling both medical outlays and insurance administrative overhead.
