over the centuries, the population size has been closely linked to the profitability of the land, since exports were rare. the resident population oscillated between 500 and 750 persons, making weiach the largest parish in neuamt. from the end of the 17th century onwards, many began to look for work outside weiach, resulting in emigration. this emigration was often to the united states. many of the forefathers of americans with the surname "baumgardner" were originally from weiach.
