I don't know if you're interested in statistics from outside the US, but if so, you should offer the ability to enter height in meters (or cm) and weight in kg.

Also, the A8 in "Paris, A8, FR" makes no sense, and it reminds me of those auto-geolocation ads that nonsensically say "Meet women in Paris, A8 now!" You should probably just drop the region altogether for most countries.

Finally, I don't think you should show any aggregate data until you get at least 4-5 responses, as you're leaking individual info. For example, just from what I've posted in this comment, anyone can deduct my height and weight from the "stats" on the site, which is not what I expected from filling out a survey (in this case I don't really care, but I'm sure others would).
