#' The idea for this data comes by way of a student encounter where we noticed
#' this issue. Data were further generated by the wonderful \pkg{WDI} package.
#' The underlying data come from the World Bank national accounts (GDP per
#' capita), World Bank analyst estimates (human capital index), or the United
#' Nations Population Division (life expectancy at birth).
