The original purpose of this project was to examine phonetic properties of sound change at the level of social networks. Several elderly people and a few cross-generational comparisons were made in 1993. Then nearly all the members of one class of sixth-graders in the Johnstown-Monroe School District, as well as 76 of their parents, were interviewed in 1994. In 1999, eight of the former sixth-graders who had formed a social clique in 1994 were reinterviewed to provide longitudinal data.
