Hey!
I am unable to select the variable PIDSE when I download the Swedish censuses 1880-1910. Why is that? Have you renamed the variable?
At https://international.ipums.org/international/resources/enum_materials_pdf/sample_design_se1880_1910.pdf you write:
“The variable PIDSE is set to the unique numeric value in
FOLK.STAM for the current person”
