Hello, and welcome to Wikipedia. Although everyone is welcome to contribute to Wikipedia, at least one of your recent edits, such as the one you made to Demographic transition, did not appear to be constructive and has been reverted or removed. Please use the sandbox for any test edits you would like to make, and read the welcome page to learn more about contributing constructively to this encyclopedia. Thank you.

 * I think that Graeme may have intended to refer to an edit to Time zone, not to Demographic transition, but his warning is equally valid. - David Biddulph (talk) 12:10, 29 March 2012 (UTC)
