This codebook is reconstructed by the IRW from the IRW data standard and the script that built it, apaza_2026_ethnic_identity.py. It is our best reading, not the source’s own codebook, and it may contain mistakes. Where the two disagree, the source data are the authority. If you find an error, please tell us.
