Hauser79: Hauser (1979) Data on Social Mobility

Description

Hauser (1979) presented this two-way frequency table, cross-classifying occupational categories of sons and fathers in the United States.

Usage

data(Hauser79)

Format

A frequency data frame with 25 observations on the following 3 variables, representing the cross-classification of 19912 individuals by father's occupation and son's first occupation.

Son

a factor with levels UpNM LoNM UpM LoM Farm

Father

a factor with levels UpNM LoNM UpM LoM Farm

Freq

a numeric vector
