"Hamlet- 0-100 residents, Village- 100-1,000 residents, and Town 1,000-100,000 residents" This is not OSM Standard tagging, there is not mention of this on wiki, Town is "an important urban centre that is larger than a place=village, smaller than a place=city, and not a place=suburb. Towns normally have a good range of shops and facilities which are used by people from nearby villages." Towns in Poland must have town rights to be tagged with this.
