I can only go by what the guy says at the site but I assume they are the rates for 2014.
The CVS files are for downloading into a spreadsheet so it would be easier to sort.
Does the guy at the site Say it is “2014”? I suppose one way to determine it is to compare some of the numbers to those at the ehealthinsurance.com website, where you can easily go into a 2013 database or a 2014 database.
