A LocalWorld will typically represent a region that has a population of  90,000 people in a Western English speaking country.  In countries where English is the primary language the population threshold may be as low as 25,000.

Any LocalWorld that represents a region whose population is bigger than 450,000 is considered a ‘major world’ and will have smaller LocalWorlds (or sub worlds) that fall underneath it. 

For instance, Melbourne, Australia whose population is over 3.7mm, is considered a ‘major world’ and therefore has the smaller sub worlds of Banyule, Boroondara and Whitehorse underneath it.

In less affluent countries with less Internet connectivity or where English is not widely spoken, the population necessary to support an online Community is usually much larger.
 

Where possible, we try to give the Worlds names that are consistent with how they are referred to by the locals of those regions, however they are listed in English so Florence Italy is not listed as Firenze, but obviously will be listed as such when the sites are translated into Italian.
