Standardized fertility measure and socio-economic indicators for each of 47 French-speaking provinces of Switzerland at about 1888.
swiss
A data frame with 47 observations on 6 variables, each of which is in percent, i.e., in [0, 100].
| [,1] | Fertility | Ig, ‘common standardized fertility measure’ |
| [,2] | Agriculture | % of males involved in agriculture as occupation |
| [,3] | Examination | % draftees receiving highest mark on army examination |
| [,4] | Education | % education beyond primary school for draftees. |
| [,5] | Catholic | % ‘catholic’ (as opposed to ‘protestant’). |
| [,6] | Infant.Mortality | live births who live less than 1 year. |
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.
