Standardized fertility measure and socio-economic indicators for each of 47 French-speaking provinces of Switzerland at about 1888.
data(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 | % involved in agriculture as occupation |
[,3] | Examination | % ``draftees'' receiving highest mark on army examination |
[,4] | Education | % education beyond primary school. |
[,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 seven 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].
