  1. Bold is used to underline % and OR
  2. 1Home sampling for finger prick/Euroimmun ELISA-S test
  3. 2People aged 15 or over, living in mainland France, but not in residential care homes for the elderly or prisons
  4. 3The sampling design is taken into account for the estimation of prevalence, crude and adjusted odds ratios, confidence intervals and tests, with the SAS procsurvey procedure. The percentages are weighted by sampling weight (the inverse of e inclusion probability), corrected for non-response probability and calibrated on the margin of the census. The prevalences are not equal to n/N. In each bivariate models, P-values are systematically given for the immigration status and for the corresponding contextual or individual adjustement variable
  5. 4First-generation immigrants: born non-French outside France and living permanently in France (including those who subsequently acquired French nationality)
  6. 5Second-generation immigrants: born and living in France, with at least one parent a first-generation immigrant
