Wikipedia's a little out of date - as is our Artyom page. Originally, Artyom was born before the war, simply several months or a year or two before the bombs fell, as he remembers his old apartment on the surface (when in reality it's pretty much biologically impossible to remember anything beyond the age of 4, but whatever) and in the novel he's a child, a baby, when he's handed off to Alex. Artyom is depicted as being about five or six in 2013 in Last Light, making him around 25 years old in 2033, and 26 in Last Light.

Hope that helps.
