Title
2016 Adult Education Survey (AES)
Subtitle
Abstract
"The aim for the 2016 AES is to further streamline and improve the data collection on adult participation in lifelong learning by both focusing on priority topics and adapting the current content to new policy needs.
[...]
According to the European statistical programme 2013-2017, the development of statistics provided on education and training includes a ‘rationalisation and modernisation of the Adult Education Survey’. The setting up of the Task Force on the 2016 AES was an essential element to define the requirements for the 2016 AES data collection in a way that takes changes and new developments in lifelong learning into account while keeping coherence with 2011 AES where appropriate. The final Commission Regulation was adopted and released in October 2014."
Coverage
Geographical Coverage
"The 2016 AES scientific use file include microdata of 32 countries: BE, BG, CZ, DK, DE, EE, EL, ES, FR, HR, IT, CY, LV, LT, LU, HU, MT, NL, AT, PL, PT, RO, SI, SK, FI, SE, UK, NO, CH, MK, BA and RS. Microdata from IE are not yet available. The total net sample size for the 32 countries is about 235 000 individuals. Some national samples include individuals aged less than 25 or more than 64 and these are included in the anonymised microdata.
Iceland and Liechtenstein did not take part in the 2016 AES. Albania and Turkey implemented an AES in 2016 but data are not available in the scientific use files because the national authorities did not allow for this dissemination."

Weighting: Method
"The weights were calculated in three steps. The first step assigns the inverse of the selection probabilities to each sampled dwelling unit. The second step adjusts for non-response, categorising the responding dwelling units by the following characteristics: county (NUTS 3) and urban/rural residency. The third and final steps consists of calibrating the secondary weights to the best latest available population totals by region (NUTS 3), urban-rural residency, gender, 4 age groups (25-34 year; 35-44 years; 45-54 year; 55-64 years) and the number of households totals by region, using the SAS macro Calmar."

Stratification Criteria
"localities are stratified by county and size. For some counties we further stratified localities by unemployment rate. Each of the 155 largest towns is a stratum of its own (self-representing towns). Besides, we have 93 strata for the smaller, non self-representing localities (these strata constitute the two-stage part of the sample design)."
(Eurostat: 2016 AES Quality Report HU)
Sampling Method
"In each self-representing towns we have a one-stage selection of dwellings with equal probability systematic random selection method, while in the non self-representing localities’ strata we applied a two-stage sampling, where PSU-s are the localities with pps selection (probability proportional to size) and SSU-s are dwellings with sys (systematic random selection). Within a selected dwelling each individual in scope was observed."

Weighting
Weighting: Method
"Weighting was carried out in three steps. The design weight is defined by the sample design.
1) The first step of weighting is the adjustment for non-response. The probability of response was estimated with logistic regression by NUTS2 regions and type of locality, using dwelling level census data as covariates.
2) Next we applied integrative, household-level calibration with the following constraints:
•population counts by region*gender*age-group
•population counts by region*degree of urbanization
•population counts by region*type of locality
3) At the final step we made some light correction for within-household non-response." (Eurostat: 2016 AES Quality Report HU)

These design weights were first corrected with the inverse of the response probability within these groups and then calibrated in order to correct the non-response and to improve the accuracy. In groups 25-34 and 35-64 the calibration classes were "education level*age group" (3*4) and "gender*region" (2*18). In groups 18-24 and 65-69 only post stratification "gender*greater region" (2*3) was conducted." (Eurostat: 2016 AES Quality Report FI)

Stratification Criteria
"Stratification was carried out separately in each voivodship (NUTS2) with consideration to its specifics. Primary sampling units were stratified according to the size of a locality. In urban areas, census enumeration areas were aggregated according to the size of towns. Cities comprised independent strata, while in the five largest cities the strata were city districts. In turn, in rural areas, the strata consisted of rural gminas (NUTS5) in subregion (NUTS3), or relatively with a few neighbouring powiats (NUTS4). Overall, there were created 205 strata." (Eurostat: 2016 AES Quality Report PL)
Sampling Method
"PSUs were selected with the use of Hanurav-Vijayan method (implemented in SAS SURVEYSELECT procedure). Separately in each stratum, a determined number of units was selected with probability proportional to the number of dwellings. Next, in each selected PSU a selection of dwellings was carried out with the use of simple sampling procedure." (Eurostat: 2016 AES Quality Report PL)

Weighting
Weighting: Method
"The applied weighting procedure included the following elements:
1. probability of dwelling selection,
2. level of completeness of the interviews in households,
3. level of completeness of individual interviews.
The above factors comprised general level of completeness on the level NUTS 2 and were used for preliminary correction of weights. Then, weights were calibrated separately for each voivodship (NUTS 2) with the use of data from current demographic estimates concerning sex, age (18-24 group and nine 5-year age groups), and place of residence (urban or rural areas).Weights for 10 larger voivodships were calibrated according to distribution covering simultaneously three variables, i.e. sex x age groups x urban/rural areas. For 6 smaller voivodships were created three marginal distributions in the following form:
- urban/rural areas x sex x age groups,
- NUTS 2 x urban/rural areas x age groups,
- NUTS 2 x sex x age groups,
- NUTS 2 x urban/rural areas x sex.
Calibrated weights were calculated with the use of the specially created program in the R system. The applied calibration procedure was analogous to the one applied in the EU-SILC." (Eurostat: 2016 AES Quality Report PL)

Stratification Criteria
"The stratification criterion is the same as that of the ECH but defined at the level of the autonomous community. The strata are defined according to the size of the municipality to which they belong:
Stratum 1: Provincial capital municipalities
Stratum 2: Self-represented municipalities, important in relation to the capitals.
Stratum 3: Other self-represented municipalities, important in relation to the capitals or municipalities over 100,000 inhabitants.
Stratum 4: Municipalities between 50,000 and 100,000 inhabitants.
Stratum 5: Municipalities between 20,000 and 50,000 inhabitants.
Stratum 6: Municipalities between 10,000 and 20,000 inhabitants.
Stratum 7: Municipalities between 5,000 and 10,000 inhabitants.
Stratum 8: Municipalities between 2,000 and 5,000 inhabitants.
Stratum 9: Municipalities under 2,000 inhabitants.
People are selected within each stratum with equal probability, by systematic sampling with random start.

"For the stratification the country is split into 56 strata (areas) that are combinations of 40 Corop areas and 13 interviewing areas (Corop = Commitee for the Co-ordination of a Regional Research Programme)." (Eurostat: 2016 AES Quality Report NL)
Sampling Method
"The AES utilised a two-stage sampling procedure. The first stage was a stratified systematic probability proportion to size (PPS) sample of municipalities. This means that municipalities are selected within each stratum with probabilities proportional to their population numbers (municipalities in random order). [...]. Subsequently, sample sizes of persons for the selected municipalities are determined. In the second stage a random sample of persons is drawn from the selected municipalities."

Weighting: Method
"The final sample weights of the LFS are used as the starting points of the design weights for the AES. The starting weight is the same for each person in the sample as each person has the same inclusion probability. Using a linear weighing method, a correction factor is calculated. This calibration process adjusted the starting weights so that the estimated totals in the gender-age group (2x4), the education level (6), degree of urbanisation (5), origin-gender group (3x2), household type (3) and the work status (5), fitted the corresponding population values. The final AES weight is equal to the starting weight times the correction factor." (Eurostat: 2016 AES Quality Report NL)

"The whole country was divided in 180 strata. These strata were defined in each NUTS III area by allocating the Municipalities and Communes according to the degree of urbanization (Densely, Intermediate and Thinly populated areas). An exception to this rule is the Greater Athens Area and the Greater Thessaloniki Area that were divided into strata formed by municipalities." (Eurostat: 2016 AES Quality Report EL)

Weighting: Method
"Weights are computed in a 3 – step procedure.
In the first step, a design weight is assigned to each person in the data file. This weight is determined by the estimated probability of selection of the particular household where the person lives in.
In the second step, a non response correction factor is computed, at primary unit level:
Non response correction = number of eligible households in primary sampling unit/number of households that responded.
At the third step, data are post stratified: Totals are computed for 208 post – stratification cells, which are defined by 13 NUTS II areas x 8 age groups x sex. These totals are estimated by weighting sample data (individuals) by design weights and non response correction factor. Finally, post stratification correction factors are computed for each individual so that estimations from Adult Education Survey are consistent with estimated (from Labour Force Survey) population totals for post - stratification cells."
