I don't know why it is so desperately needed, but Saint-Pierre-et-Miquelon seems to have lost about 3% population during this period, going from 6300 in 1999 to 6069 in 2012.

Saint-Pierre-et-Miquelon, New Caledonia, French Polynesia and Wallis-et-Futuna are rarely included in such stats as they are not part of the EU and not geographically part of Europe either, unlike French Guiana and the others which are part of EU, so at least part of Europe in a political sense.

(Symbiote, all of these territories are very much part of France though, just under different rules for some of them.)

I don't know where you're going with Clipperton though, it's sometimes illegally visited and trashed by fishers and such, but they can't be considered a population in any sense.
