Hi, I'm using a cumulative dataset of the European Social Survey from 2002-2018.
In my analysis I want to control for household net income, a variable which has been changed in the dataset over time.

In ESS 2002-2006 the income variable (hinctnt) has 12 numeric values whereas the income variable (hinctnta) in ESS 2008-2018 has 10 numeric values.
I want to create a new variable which combines the 12 and 10 numeric values resulting in 22 income values or categories (in other words I do not want to combine the numeric value of for example 1 for the two variables).


Attatched are two codebook commands of the relevant variables

Kind regards
