Non-response Weight: Method
In the event of non-response, a duplication procedure is used, i.e. if it proves impossible to hold interviews at a given dwelling, an attempt is made to compile a series of characteristics for the type of family, and to find another family with the same characteristics in the same section and duplicate its replies.
As the sample is not stratified, the survey findings are grossed-up to the total population (as estimated by the INE's Demographic Studies Centre) using as a weighting factor the ration between this estimate and the total population in the sample.

Non-response Weight: Method
To compensate for non-response all households are cross-classified by the following variables: category of dwelling, employment status of the head of household, category of commune, size of household, sex and age of the head. These characteristics for the non-responding households are based on information collected either from the current survey or the preceding one.
Coverage Adjustment Weight: Method
An independent estimate based on 1982 census projections of the population falling into five-year age group/sex categories is divided by the survey estimates derived from the previous two factors to provide a national age-sex factor, which is then entered on all records belonging to the appropriate category. The national estimates thus derived refer only to persons living in private households.

Grossing to population counts and adjustments for non-response were based on a post-stratification according to sex and age within each arrondissement. In each of the classes thus formed, a weighting coefficient was calculated, using the estimated sex and age structure of the population on January 1.

Stratification Criteria
In England and Wale the population to be surveyed was divided into three major strata according to the type of local authority district in which they lived: local authoirites in the metropolitan counties and Greater London, local authorities which either had a population density of at least 2 persons per hectare and a population greater than 125 000 or had a population density greater than 24 persons per hecatre; and remaining local authorities.

Non-response Weight: Method
The adjustment procedure is based on a three-stage a posteriori stratification. Figures are based on independent demographic estimates. The stratification variable for the first stage is the Local Authority District. This stage makes it possible to make adjustments for different rates of non-response in the various local authority areas and ensures that the results are geographically representative. The second-stage variables are sex by age band This stratification is intended to ensure that the age profile of the 16-24 year old is correct at national level. The variables in the third stage are region, sex and age band
The three stages are applied by means of an iterative procedure designed to ensure that the estimates are consistent with the stratification variable sets.

Whenever a household can not be interviewed for any reason it is subsituted by another.
The population adjustment of the sample results is carried out stratum by stratum for men and women separately. In this adjustment procedure use is made of the most recent population estimates calculated monthly by Istat, using data from the municipal registers.

Using as criterion the degree of urbanization, the localities of the country are allocated to 10 major strata. 8 strata are further subdivided into the nine administrative regions of the country; the stratum of Greater Salonica is divided into 10 and that of Greater Athens into 40 equally sized sub-strata.

Non-response Weight: Method
Both the non-response adjustment and the total population adjustment were made on the basis of a post-stratification. The stratification variables used were sex, year of birth and geographical region.
The results have been adjusted by the calculation of one factor per family on 1 January. All persons in a given family are allocated the same factor values. Adjustment factors are calculated by means of post-stratification, which divides the sample into strata according to the size of family, age, sex, part of the country and urban/rural situation.

Non-response Weight: Method
Adjustments for non-response and listings which do not contain a dwelling unit were made by modifying the grossing-up factor, at PSU level, by a factor (1 + (population of non-response units) / (population of respondent units)).
Coverage Adjustment Weight: Method
A population adjustment, at regional level, was carried out for
males and females separately by five-year age groups to ensure that the survey population estimates were identical to independent official population estimates.
