In actuality though, Ohioans and Californians will see pretty similar premiums on the new marketplaces. There's a $16 difference between the two states.
One other important thing to keep in mind: These are the prices before federal tax subsidies, which will go out to many Americans between 138 and 400 percent of the federal poverty line (about $15,000 to $45,000 for an individual). These are, essentially, the maximum prices for people who earn above that threshold. Below the threshold, many will get a significant discount on these rates.
