Tightening up the fight to offer the health law, President Barack Obama was expected to give a speech Thursday touting how people purchasing protection in the new online marketplaces this fall will pay lower-than anticipated premiums on average in no less than 10 states and the District of Columbia.

On Wednesday, the New York State regulators approved the health insurance rates for individual policies for 2014 that are at least half the cost of current policies on average.

On Thursday the administration released a fact sheet showing the average insurance premiums for individuals buying health insurance on their own and small employers will be lower than previously projected not just in New York, but in at least nine other states and the District of Columbia.On average premiums will be 18 percent less expensive those states.

The propose and final premium rates for California, Colorado, New Mexico, New York, Ohio, Oregon, Rhode Island, Vermont, Virginia, Washington and D.C. were included since they have been publicly announced. But these states are not representative of the rest of the country since most support the law and have their own insurance marketplaces.

Critics of the health law have long said that its fees, broad benefit requirements and others rules will cause rates to skyrocket. Others cautioned that the report averages premium costs and actual premium prices are likely to vary widely.“The impact of the ACA will vary considerably depending on a person’s age, gender, health status, and where they live,” said Robert Zirkelbach, spokesman for the America’s Health Insurance Plans. “Simply looking at averages doesn’t tell you what these reforms are going to mean for a particular person in a particular state.”

The new premium rates do not affect the majority of Americans who receive insurance through their employers, only those who buy it on their own.

Senior administration officials said the analysis compared the rates submitted by insurers in those states and DC with projections from the CBO, which has previously estimated what premiums might look like after the law is implemented. Although the HHS has not released on how the calculations were made.

Most people expected to sign up are expected to qualify for sliding scale federal subsidies, which will offset some of the premium costs. Subsidies are available to people earning up to 400 percent of the federal poverty level, or about $46,000 for an individual. In addition, none of the analyses can give an accurate report on how much someone will pay because rates will vary by by age, geographic location, and by insurer. Consumers will still be looking for information on the new rates.

The greater part of the rates acknowledged in the HHS study are almost always submitted in states that will supervise their own marketplaces, as opposed to depending on a exchange run by the federal government. A few specialists say those states may see lower-than wanted rates in light of the fact that guarantors suppose they may be better provided to market to more youthful and healthier individuals. A percentage of the state-run trades, for example the one in California, additionally arrange rates with safety net providers, which can help push down premiums.

“The Republicans will say there is something wrong with numbers and it doesn’t tell you everything need to know,” said Antos. “The Democrats will say this proves the president’s plan is working.”
