Officials at state insurance exchanges say they expected older and sicker consumers to sign up first. They think younger people will sign up later in the open-enrollment period, which runs through March. White House officials have said they need about 40 percent of the consumers who buy plans on the exchanges to be younger than 35. "Those are pretty solid enrollment numbers for a younger demographic," said Michael Marchand, a spokesman for Washington state's Healthplanfinder. "Ideally we'd like to see the number go up in coming months."
