## Swiss Fertility and Socioeconomic Indicators (1888) Data

### Description

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

### Usage

    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 have been available at http://opr.princeton.edu/archive/eufert/switz.html or http://opr.princeton.edu/archive/pefp/switz.asp.

They state that variables `Examination` and `Education` are averages for 1887, 1888 and 1889.
