Stratification Criteria
For dwellings in the 1981 Census of Housing and Dwellings, stratification was carried out within each Länder using data taken from the census on social status and level of education of the head of household; number of occupants; age, size and facilities of dwelling. Combining these variables gives 1651 strata. The list of new buildings constructed in each year form separate annual strata.

Non-response Weight: Method
The stratum consisting of newly constructed buildings is given greater weight. This compensates for the non-inclusion of very recently constructed buildings due to the time lag between buildings being constructed and the sampling frame being updated.
Coverage Adjustment Weight: Method
The grossed-up population is constrained to independent population estimates by Länder, sex and age band, with the further constraint that the total population of foreigners agrees with the latest population estimates. An iterative process is carried out which ensures that all members of a given household have the same weight.
The sample taken from collective households with more than 50 residents is grossed up to the total population in collective households.

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.

The first stage adjusts for non-response by post stratifying by degree of urbanization, by whether first, second or third interview, and weighting the responses in each strata by the reciprocal of the response rate for that strata.
Coverage Adjustment Weight: Method
The second stage uses a generalized Raking Ratio method to adjust the weight for each household so that the survey estimates agree with independent population estimates for sex by five year age band. This method ensures that individual and household analyses give consistent results.

Every quarter, population projections by age group and Spanish provinces (NUTS 3) are calculated. Projections by age and region are distributed by stratum in proportion to the population of each stratum. In each stratum, age group and region, the weighting is determined by the ratio of the projection to the sample size.
Coverage Adjustment Weight: Method
The sample is calibrated in order to adjust to the population disribution. The auxiliary information used is the population by sex, age, nationality and NUTS 2. A linear weighting method is used, in which each member of the household has the same weight.

Non-response Weight: Method
A two-stage adjustment procedure is used.
(a) If possible, limited data are collected for households which fail to respond. These data can include: number of members of the household, and for households comprising only one person: age and sex. From this data, the weightings of respondent households are increased to take account of non-response in the region.
(b) The sample, weighted to take account of non-response, is stratified a posteriori by region, sex, age and nationality and is extrapolated to the population.

Stratification is carried out by administrative region by degree of urbanisation. The localities of the conutry (apart from Greater Salonica and Greater Athens) are put into one of 8 strata depending on the size of population of the locality. These strata are further divided by the nine administrative regions. Greater Salonica and Greater Athens are divided into, 10 and 40 respectively, equally sized strata.
