Description

Standardized fertility measure and socio-economic indicators for each of 47 French-speaking provinces of Switzerland at about 1888.

Usage

data(swiss)

Format

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.

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.
