#' Cross-National Rates of Trade Union Density
#'
#' Cross-national data on relative size of the trade unions and predictors in 20 countries.
#'  This is a data set of interest to replicating Western and Jackman (1994),
#'  who themselves were addressing a debate between Wallerstein and Stephens on
#'  which of two highly correlated predictors explains trade union density.
#'
#' @format A data frame with 20 observations on the following 5 variables.
#' \describe{
#' \item{\code{country}}{a character vector for the country}
#' \item{\code{union}}{a numeric vector for the percentage of the total number of
#'  wage and salary earners plus the unemployed who are union members, measured
#'  between 1975 and 1980, with most of the data drawn from 1979.}
#' \item{\code{left}}{a numeric vector tapping the extent to which parties of
#' the left have controlled governments since 1919, due to Wilensky (1981).}
#' \item{\code{size}}{a numeric vector measuring the log of labor force size,
#' defined as the number of wage and salary earners, plus the unemployed.}
#' \item{\code{concen}}{a numeric vector measuring the percentage of employment,
#' shipments, or production accounted for by the four largest enterprises in
#' a particular industry, averaged over industries (with weights proportional
#' to the size of the industry) and the resulting measure is normalized such
#' that the United States scores a 1.0, and is due to Pryor (1973).
#' Some of the scores on this variable are imputed using procedures
#' described in Stephens and Wallerstein (1991, 945).}
