Changes in the British class structure at age 38

Yesterday I plotted the distribution of men and women by class at age 27 in four British birth cohorts, using data from a recently published paper. However, many individuals will not have reached their final class position by age 27 (as a friend of mine points out), meaning that the proportion of people eventually ending up in Classes 1 and 2 will have been underestimated. Accordingly, below I plot the distributions of men and women by class at age 38 in each of the first three birth cohorts (data for this age on members of the 1980-84 cohort are obviously not yet available). 

In the case of men, there has been a rise in membership of Classes 1 and 4, along with a decline in membership of Classes 2 and 7. In the case of women, there has again been a rise in membership of Classes 1, 2 and 6, along with a decline in membership of Classes 3, 5 and 7.
