sentences:  Breitenbach was originally purely a farming village, but from the mid 18th century grew bit by bit into a village of industrial workers, helped along by the growth in coal mining.Since the mid 20th century, it has been held to be a residential community for people employed in all kinds of occupations, and who for the most part must commute to work outside the village.Extensive figures are available about Breitenbach's population development, according to which 13 families with some 70 inhabitants lived in the village in the Late Middle Ages.
