Q: The latest Obamacare numbers are out and they don't reveal all that much. 
  
 According to figures released by the U.S. Department of Health and Human Services, about 2.1 million people have signed up for private insurance through the end of last year on the federal HealthCare.gov website or a state-run exchange. 
  
 Here's what you need to know: 
  
 Obamacare is lagging behind predictions. The administration once estimated it would have 3.3 million people signed up by this point and it hopes to have seven million by the end of March. 
  
 Not enough young people have signed up yet.Twenty-four percent of those who have signed up are between 18 and 34, below the 40 percent needed to keep costs down. 
  
 Most people chose the second-cheapest plan. According to HHS, 60 percent chose a “silver” plan and only 20 percent chose the cheapest, “bronze” plan. 
  
 Nobody knows how well the law is working. The figures released by the federal government do not include how many of the people who signed up were previously uninsured. 
  
 All that said, there are still two and a half months until the end of enrollment for 2014, and the experience in Massachusetts with a similar law showed that many people — especially many young people — waited until the last minute to sign up. 
  
 So take a deep breath and stay calm before reading any pronouncements on what the latest figures mean. It's still too soon to tell. ||||| Today the federal government released the most comprehensive data yet about who signed up for Obamacare through Dec. 28. There's reason to cheer for both the law's supporters and its detractors. Let's start with the good news for Obamacare fans. President Barack Obama's administration predicted -- or, well, prayed -- that enrollment in the law's state insurance exchanges, which was initially anemic, would accelerate toward the end of 2013, as the deadline approached for getting coverage by this month. 
  
 As you can see from the accompanying charts, that prediction came true: More than 2 million people had chosen exchange plans by Dec. 28, almost a five-fold increase over the number enrolled a month earlier. The number of people who were deemed eligible for Medicaid also increased, but not at the same rate as private coverage. 
  
 The accompanying chart also shows that federally run exchanges, which initially performed worse than those operated by the states, are now enrolling people at a quicker rate than state exchanges. That's a validation of sorts for the Department of Health and Human Services, as it supports the notion that it's learning from its early mistakes. 
  
 There's still plenty of work to do. For starters, in some states the number of women enrolling in Obamacare coverage exceeds the number of men, out of all proportion with demographics. But that doesn't mean the law isn't working; it means the administration needs to find better ways to persuade men to sign up for coverage. 
  
 Now, the good news for detractors. The government said last year that to get the right balance between healthy and sick people on the exchanges -- and, by extension, to produce affordable premiums -- it needed 2.7 million people between 18 and 34 to sign up for coverage. That's about 40 percent of the estimated seven million who would sign up overall for 2014. The accompanying chart shows the exchanges aren't hitting that goal. Just 24 percent of those who have chosen a plan were between 18 and 34. By contrast, the largest share of enrollees -- one third -- are between 55 and 64. 
  
 (There's a caveat here: The administration could claim that its definition of young and healthy covered everyone under 35, including the 6 percent of exchange enrollees who are under 18. That would still leave it short of its stated goal, as well as looking a touch eager to persuade the naysayers.) 
  
 As you can see from the right-hand side of the chart, that's significantly different from the age breakdown of the uninsured population, which skews much more heavily toward the young. So one of two things is happening here. Either the old and sick are self-selecting into Obamacare, which spells trouble for insurers (and, by extension, the government, which backstops insurers against higher-than-expected risks). Or young people without insurance are taking their sweet time signing up but will do so before the March 31 deadline. The administration is obviously hoping for the latter. 
  
 Today's numbers don't settle the question of whether the administration will hit its goals for enrollment in the exchanges, measured either in raw numbers or demographic breakdown. But they show that those goals are within reach.

 Questions about the law’s financial viability are likely to become the next line of attack from its critics, as lawmakers gear up for the midterm elections this fall. Republicans quickly seized on the government’s progress report on Monday as evidence that the health insurance law would not work. 
  
 But administration officials expressed optimism that more young people would sign up in the months ahead, calling the latest enrollment numbers “solid, solid news” for the health care law. They said that interest in obtaining insurance through the marketplaces was increasing sharply across all age groups and that youth outreach efforts would become more aggressive as the March 31 open enrollment deadline approached. 
  
 “We’re pleased to see such a strong response and heavy demand,” said Kathleen Sebelius, the secretary of health and human services. “Among young adults, the momentum was particularly strong.” 
  
 Of those who signed up in the first three months, administration officials said, 55 percent are age 45 to 64. Only 24 percent of those choosing a health insurance plan are 18 to 34, a group that is usually healthier and needs fewer costly medical services. People 55 to 64 — the range just below the age at which people qualify for Medicare — represented the largest group, at 33 percent. 
  
 The latest figures about enrollment add pressure on the Obama administration after a disastrous rollout of the HealthCare.gov website in October. Senior officials said they understood the stakes and were working to increase sign-ups. The White House recently hired Marlon Marshall, the deputy national field director for Mr. Obama’s 2012 presidential campaign, to run a campaign-style effort aimed at increasing sign-ups, especially among young people. 
  
 Brendan Buck, a spokesman for the House speaker, John A. Boehner, Republican of Ohio, predicted that the White House would fail to meet its goals and said that insurance premiums would rise. 
  
 “There’s no way to spin it: youth enrollment has been a bust so far,” Mr. Buck said. “When they see that Obamacare offers high costs for limited access to doctors — if the enrollment goes through at all — it’s no surprise that young people aren’t rushing to sign up.” 
  
 The demographic information, which had not been broadly available until Monday, also offers the first concrete evidence about whether the national health care experiment will work the way it has in Massachusetts, where a government marketplace also offers insurance to people who do not receive it through their employers. Officials said they were optimistic because the pattern of sign-ups among young people looked similar to the one they had seen in that state, which had a surge in sign-ups as the deadline approached. 
  
 Over all, officials said that 2.2 million people had signed up by Dec. 28 for health insurance through HealthCare.gov and the state-based websites. Administration officials have previously said they hope to see seven million people enrolled in private health plans through the federal and state exchanges by March 31. 
  
 Of those who signed up, about 54 percent are female and 46 percent are male. Nearly 80 percent of those who selected a plan qualified for federal subsidies to reduce their premiums, officials said. Federal officials said they did not know how many people selecting plans were previously uninsured or how many have paid premiums. People are required to pay their share before coverage takes effect. Officials also did not know the race or ethnic origin of those who signed up. 
  
 The age breakdown was the most highly anticipated data being released because of what it could say about the health of those who will be insured. Under the law, insurers can no longer deny coverage or charge higher premiums because of a person’s medical history or pre-existing conditions. As a result, White House and health policy experts have repeatedly said that insurers need to sign up large numbers of younger people to balance the financial risks of covering older Americans who require more medical care. 
  
 Larry Levitt, a senior vice president of the Kaiser Family Foundation, has said that “the mix of enrollment is much more important than the total number.” 
  
 “If you assume that sicker individuals are likely to come in first, then a smaller pool is likely to be a sicker pool,” Mr. Levitt said. “The best guarantee of a diverse pool is a big pool, because that means you are probably reaching younger and healthier people.” 
  
 Mr. Levitt said that people enrolling early included some with the greatest needs: people who had been locked out of the individual insurance market because of serious illnesses and those coming from federal and state programs for people with pre-existing conditions. 
  
 The report from the administration showed that older Americans accounted for a large share of those choosing health plans in a handful of states, including West Virginia and Wisconsin, where 66 percent were age 45 to 64. In Maine, 64 percent were in that age bracket, and in Arkansas their share was 63 percent. 
  
 Robert Laszewski, a consultant who works closely with insurers, said, “You need healthy people of all ages,” and so far, he said, “the program is not ramping up fast enough to guarantee a good balance of healthy and sick people, which you need to sustain the program.” 
  
 Robert E. Zirkelbach, a spokesman for America’s Health Insurance Plans, a trade group, said “it’s too early to know” if the enrollment of younger and healthier people was adequate to keep premiums stable in coming years. Insurers will need to see enrollment numbers for the full six-month period, he said. 
  
 Many people who bought insurance on their own have received notices saying their policies were being canceled or discontinued because the policies did not comply with coverage requirements of the new health care law. Those expecting high medical bills had the strongest motivation to overcome the obstacles to buying insurance on the federal exchange. 
  
 Caroline F. Pearson, a vice president of Avalere Health, a research and consulting company, said that “early enrollment is skewed toward older individuals.” She added: “Sicker, older folks tend to sign up first because they are more motivated. They are likely to have health care costs early in the year.” 
  
 Anne Filipic, the president of Enroll America, a nonprofit group trying to expand coverage, said, “We know from our research that when uninsured consumers learn about the financial help that is available to them, they are eager to enroll.” 
  
 Health plans in the marketplace are separated into four categories — bronze, silver, gold and platinum — indicating the generosity of coverage, or the share of costs paid by insurance for an average enrollee. Of people choosing plans so far, 60 percent selected silver plans and 20 percent signed up for bronze plans. Thirteen percent chose gold plans, and 7 percent platinum coverage. 
  
 In December, for the first time since the marketplaces opened, the number of people selecting plans in the federal exchange exceeded the number signing up through state exchanges. 
  
 For the first half of the enrollment period, through December, the federal exchange, which serves 36 states with about two-thirds of the nation’s population, accounted for 56 percent of those selecting plans. The other 44 percent were in state exchanges. |||||
A: 
So far, most people signing up for ObamaCare are on the older side—a trend that could force insurance premiums to rise if younger, healthier enrollees remain a minority, the New York Times reports. The first official release of ObamaCare numbers shows that 2.2 million people enrolled in the first three months. Among them, 55% are ages 45 to 64, 24% are 18 to 34, and about a third are 55 to 64. Naturally, the Obama administration is putting a positive spin on it and Republicans are pouncing. Among the reactions: "We’re pleased to see such a strong response and heavy demand," said health secretary Kathleen Sebelius. "Among young adults, the momentum was particularly strong." "There’s no way to spin it: youth enrollment has been a bust so far," said a spokesman for John Boehner. "When they see that ObamaCare offers high costs for limited access to doctors ... it’s no surprise that young people aren’t rushing to sign up." The numbers don't really mean much, according to a quick Denver Post analysis. For one thing, it's unclear how many enrollees were uninsured to begin with. And the Post notes that with RomneyCare, "many people—especially many young people—waited until the last minute to sign up." On the plus side, the number of people enrolling jumped 500% over a single month, and federally run exchanges are now outpacing state exchanges, notes Bloomberg. On the downside, the age breakdown could indeed raise insurance premiums. Click to see why the Spanish-language ObamaCare site has become its own problem.
