Understanding Society User Support

Hi,

Sorry if this is a silly question, I'm still getting to grips with the dataset and coding with R. I just redownloaded "Understanding Society: Waves 1-15, 2009-2024 and Harmonised BHPS: Waves 1-18, 1991-2009" to check, but the values given for the ukborn variable on xwavedat.dta (shown below) don't match with the values shown on the ukborn variable on your website. Am I missing something or is this normal?

ukborn                         n
  <dbl+lbl>                  <int>
1 -9 [missing]               52325
2  1 [Yes, England]          71020
3  2 [Yes, Scotland]         10661
4  3 [Yes, Wales]             7110
5  4 [Yes, Northern Ireland]  6697
6  5 [Not born in the UK]    19395

Thank you very much,
Emily
