[BDSP. Notice produite par INIST 3tbQR0xc. Diffusion soumise à autorisation]. Objectives-To determine whether, in the context of a face to face interview, socioeconomic groups differ in their propensity to provide details about the amount of their personal income, and to discuss the likely consequences of any differences for studies that use income based measures of socioeconomic position.

The socioeconomic characteristics of income non-reporters were initially examined using sex specific age adjusted proportions with 95% confidence intervals. Multivariate analysis was performed using logistic regression.

Results-The overall rate of income non-response was 9.8%. (...)
