The population figure in the infobox has recently been changed according to a known source (4.2bn in 2370, according to Stellar Cartography), but can anybody find a source for the previous figure (8.2bn in 2373) at all? Since MB uses the POV of an unknown point in the future to which all events described in any given source are in the past, it would make sense to use the figure that is most recent, if at all possible.
