This issue of minority populations and linguistic change for anglophon
e and francophone groups in Quebec and Ontario is very important, affe
cting relationships between the groups and individual perceptions of s
ocial power. This paper begins an analysis of linguistic change in the
transition or contact zone of bilingualism along the Quebec-Ontrio bo
rder in the period 1961-86. Written in both languages, it describes ch
anges in absolute numbers and percentage share of the total population
of the minority group, anglophones in Quebec and francophones in Onta
rio. It defines regions of change, and, combining the two measures in
a series of graphs, shows levels of change at the local level.
