The accuracy of the basic figures is probably unimportant so long as everyone uses the same information. If it's just a game, it doesn't really matter whether or not Dave's App gives accurate figures or not, that only becomes important if the maps are to be used outside of the Forum - such as lodging as submissions when the redistricting actually happens. Heck, if it's just a game, you could use 1932 figures and it wouldn't really matter! I think so long as everyone's got the same numbers and everyone's judged according to the same set of rules (see Muon's post), it doesn't matter whether or not the figures we're using are absolutely 100% correct.
