Recent research on the linguistic adjustment of minority-language spea
king immigrants in several destinations has found that acquisition of
destination language skills is inhibited by living in an area where ma
ny others speak the same minority language, This paper uses a unique d
ata set for Australia (1988) that includes a variety of ethnic network
variables to analyze the role of the language concentration measure,
These ethnic variables, in particular, ethnic press, relatives in Aust
ralia, and spouse's origin language, are highly statistically signific
ant. Their inclusion in the equation eliminates the effect of the mino
rity-language concentration variable, The model for analyzing the dete
rminants of English reading and English writing skills in Australia is
also shown to be very similar to the model for speaking fluency, incl
uding the effect of the ethnic network variables.
