 ::You most certainly are not being pedantic (or if you are, it certainly isn't a problem; accuracy and clarity are important!). I agree that you are correct, that the term ""rate of health insurance coverage"" does indeed refer to the number of persons insured. However, I do think that saying ""rate of health insurance coverage"" implies to lay readers ""insurance rates"", commonly meaning ""premiums"", and that this would be a source of confusion. While the wikilink can help to clarify, I don't think that readers should have to click it to understand what is meant. That said, I'm not especially attached to the language I added, and perhaps I am overestimating the potential confusion. So, how about this: let's keep your language for now. By all means, go ahead and nominate the article for GA status. I just ask that during the GA review, we see if the reviewing editor(s) bring it up on their own, and if they don't, then we ask them their opinion(s) as to whether they think it's confusing. If others think it's confusing, we'll change it (maybe, but not necessarily, to the way I had it); otherwise, we'll keep it. Sound fair? 
 ::By the way, I do think the article is a serious GA contender, especially given the number of reliable sources you have added over the past week. It could still use a bit of copy-editing, but its substance and sources are right on. Great work! –  ·  "
