  1. Outmigrant ascertainment for bias assessment in environmental epidemiology.

    Article - En anglais


    In the summer of 1985, the McGill Epidemiology Rapid Response Unit undertook a study comparing two areas exposed to emissions of « sour gas » refineries to an unexposed area.

    One operational objective of the project was the identification and survey of all the people who had lived in the study area but had since moved (outmigrants).


    We estimated the number of outmigrants (people who had ever lived in the area during the period 1957 to 1985) to be 3363 by using information obtained from our cross-sectional survey and from population statistics for the area of interest.

    Ten different methods combined lead to the identification of approximately 87% of all the outmigrants who left the study area during that period.
