A number of recent studies measure trade union membership concentration using the Herfindahl index. This study uses the same measure to examine the relative effects of the different factors that influenced the level of British union membership concentration between 1892 and 1987. Five factors are identified as influencing this development: mergers, formations, dissolutions, breakaways, and membership change. Marked occupational differences in the relative effect of these factors are shown. In aggregate terms, mergers and membership change tend to be complementary in effect until 1946 and counteractive thereafter.
