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 <URL:

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