Does it make sense to keep changing zone names to track ever changing demographics?  I don't think so.

If the capital of the country is in the zone in question, that's the only city name that makes sense.  If a zone needs to be named for some place other than the capital, then it makes sense to pick a big city, or the best known city.  But pick it and stick with it, don't try to keep changing things to track population shifts.  That just creates churn for no benefit.  Especially in this case, where both city names are well known.
