Details
(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].
Note
Files for all 182 districts in 1888 and other years are available at http://opr.princeton.edu/archive/eufert/switz.html.
They state that variables Examination and Education
are averages for 1887, 1888 and 1889.
