What, by 2042? There's no chance that it will take all the way to 2043 for this to occur? I wish I could be as confident in predicting events three decades yet to come!

(So far as I can tell from tracking down the press release and then the study in question, the prediction in question was formed by estimating birth, death, and migration factors for each age group within each demographic and performing the necessary calculations. Error bars are not indicated anywhere I have found.)
