Can government get people to buy a product that millions think isn’t worth the price?

That’s the question that health care analysts are asking as they pore over the results of the Obamacare open season that concluded on February 15.

On the surface, the data released earlier this month by the Department of Health and Human Services are encouraging. Nearly 11.7 million people selected a plan this year, compared with just more than 8 million during the 2014 open season.

There are some cautionary signs. Despite the influx of new subscribers, the age profile continues to skew older. Nearly half are 45 or older and 26 percent are over 55. Interest among the young remains largely unchanged over last year.

So is interest among middle income people who lack coverage. Enrollment has been dominated by those with the lowest incomes. HHS reports that 83 percent of people who have selected plans have incomes between 100 percent ($11,770) and 250 percent ($29,425) of the federal poverty level (FPL). Medicaid, meanwhile, has grown by nearly 20 percent since Obamacare was launched, swelling its ranks to 70 million. Roughly 22 percent of the U.S. population is now on Medicaid, despite the refusal of 22 states to expand their programs.

(Reuters) – Arizona Republican Governor Doug Ducey signed a law on Monday that requires doctors to tell women that drug-induced abortions can be reversed and that blocks the purchase of insurance on the Obamacare health exchange that includes abortion coverage.

The requirement that patients be told that the effects of abortion pills may be undone by using high doses of a hormone was the most hotly contested provision during legislative debate.

Supporters said there was ample evidence the reversal was possible if acted upon quickly, although they provided no peer-reviewed studies in support of their position.

Two reports released in the past week demonstrate a potential bifurcation in state insurance exchanges: The insurance marketplaces appear to be attracting a disproportionate share of low-income individuals who qualify for generous federal subsidies, while middle- and higher-income filers have generally eschewed the exchanges.

On Wednesday, the consulting firm Avalere Health released an analysis of exchange enrollment. As of the end of the 2015 open-enrollment season, Avalere found the exchanges had enrolled 76% of eligible individuals with incomes between 100% and 150% of the federal poverty level—between $24,250 and $36,375 for a family of four. But for all income categories above 150% of poverty, exchanges have enrolled fewer than half of eligible individuals—and those percentages decline further as income rises. For instance, only 16% of individuals with incomes between three and four times poverty have enrolled in exchanges, and among those with incomes above four times poverty—who aren’t eligible for insurance subsidies—only 2% signed up.

The Avalere results closely mirror other data analyzed by the Government Accountability Office in a study released last Monday. GAO noted that three prior surveys covering 2014 enrollment—from Gallup, the Commonwealth Fund, and the Urban Institute—found statistically insignificant differences in the uninsured rate among those with incomes above four times poverty, a group that doesn’t qualify for the new insurance subsidies.
