All variables but ‘Fertility’ give proportions of the population.
(paraphrasing Mosteller and Tukey):
Switzerland, in 1888, was entering a period known as the demographic transition; i.e., its fertility was beginning to fall from the high level typical of underdeveloped countries.
The data collected are for 47 French-speaking “provinces” at about 1888.
Here, all variables are scaled to [0, 100], where in the original, all but
Catholic were scaled to [0, 1].
Files for all 182 districts in 1888 and other years have been available at https://opr.princeton.edu/archive/pefp/switz.aspx.
They state that variables Examination and Education are averages
for 1887, 1888 and 1889.
