President Donald Trumpsinterview with The New York Times generated plenty of headline-making comments.But his remarks on health insurance, the biggest topic of the week, suggested he didnt know how it works or how much it costs.

He said:

So pre-existing conditions are a tough deal. Because you are basically saying from the moment the insurance, youre 21 years old, you start working and youre paying $12 a year for insurance, and by the time youre 70, you get a nice plan.

The notion of paying $12 a year for health insurance is even less than the $15 per month number Trump floated in an interview with the Economist earlier this year.

Insurance is, youre 20 years old, you just graduated from college, and you start paying $15 a month for the rest of your life and by the time youre 70, and you really need it, youre still paying the same amount and thats really insurance, he said in the May interview.

The Kaiser Family Foundation estimated that the average monthly premium in the United States in 2013 was $235.27 per person, with a high of $473.17 in New Jersey and a low of $157.97 in Utah.

All of those numbers are significantly higher than either figure suggested by the president. This prompted a number of observers to wonder if Trump was confusing health insurance with the life insurance ads that air in heavy rotation on cable news.
