- Dataset
- Demographic Variables & Sample Weights
CDC/NCHS releases RIAGENDR consistently as the same two-category demographic variable across Continuous NHANES, with code 1 for Male and code 2 for Female. Indexed DEMO-file method, target, and weight changes do not by themselves establish a change in the variable's released coding or longitudinal construct.
Evidence provenance: CDC/NCHS source-confirmed evidence · Praxis deterministic adjudication
Evidence signals: source-stated
Praxis harmonization actions
- Pool the released RIAGENDR categories directly across calibrated cycles. Apply cycle-appropriate NHANES survey weights and design variables separately, and do not reinterpret RIAGENDR as a gender-identity measure beyond the released CDC/NCHS coding.
