Early town organization in Vermont and much of New Hampshire proceeded in a somewhat different manner from that of the other New England states. In these areas, towns were often "chartered" long before any settlers moved into a particular area. This was very common in the mid to late 18th century—although there were towns which predated that period and were not part of this process in southeastern New Hampshire, such as Exeter. Once there were enough residents in a town to formally organize a town government, no further action was necessary to incorporate. This practice can lead to inconsistencies in the dates of incorporation for towns in this region. Dates given in reference sources sometimes reflect the date when the town was chartered, which may have been long before it was settled, and not the date when its town government became active. In other parts of New England, some "future towns" were laid out along these lines, but such areas would not be formally incorporated as towns until they were sufficiently settled to organize a town government.
