Yes, Jasper was created when he was 20 in the late 1800's.
emmets older
Because Jasper has been a vampire longer than Emmett no Jasper is 21 and Emmett 20
Jasper Hale doesnt have an exact age. He has lived since the Civil War so he is older than Emmett but if you mean as part of the Cullen family then Jasper and Alice are the last to join, next to Bella.
Alice and Emmett Cullen, and Rosalie and Jasper Hale
Jasper Hale because, Emmett was changed in 1915 . Jasper was changed in the 1800's because, he was in the civil war

In vampire and human years Jasper is the oldest from the two. Jasper was transformend in 1863 and Emmett was transformned in 1953. Jasper was 20 when he was transformed and Emmett was transformned when he 20. technically Jasper is older as of 2009 he's 166. Emmett is of 2009 76. Hope it helps. I may be wrong though so I don't know. :)
