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."

(Eurostat (2017): 2016 AES manual - Annexes. Version 2)

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."

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."

    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."

    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)

    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)

    "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)

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 Adult Education Survey in Greece covers the residents population living in private households aged 18 - 64 years old.

    Target Sample Size

    Cross-sectional Data
    Achieved Sample Size 5469

    Available Data

    • Cross-sectional

    Sampling Procedure

    Source Of Sampling Frame

    The basic sampling frame is an area frame: it is a full list of all building blocks in Greece, compiled at the last census.

    Sampling Design

    • Probability
    • systematic
    • stratified
    • multi-stage

    Primary Sampling Units

    Area units

    Secondary Sampling Units

    Dwellings

    Stratification Criteria

    "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

    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."
