Technical report - b) Response to the survey and characteristics of the interviewed sample

Tuesday 26 November 2002

This chapter gives details of response to each of the main components of the survey and describes the main characteristics of the responding sample (those who completed the dietary interview) and the diary sample (those who completed a full seven-day dietary record).

Where possible the characteristics of the sample are compared to those of the population as a whole, using population estimates, or with data from the 2000 General Household Survey (2000 GHS) .

The General Household Survey is a large-scale household survey that provides comparative data across a range of subject areas, including socio-demographic characteristics, access to amenities and consumer durables, and consumption of alcohol.

Data from the 2000 GHS for 19 to 64 year olds are used for comparative purposes throughout the NDNS published volumes where appropriate.
