Other Household Survey
The STEP project consists of Household Surveys collection and Employer Surveys collection.
These surveys are part of the STEP Household Surveys collection.
So far, two waves have been implemented in 12 countries. The third wave is under preparation.
The first wave started in September 2011 and was completed in December 2013. Wave 1 countries are: Bolivia, Colombia, Sri Lanka, Lao PDR, Vietnam, the Yunnan Province in China, Ghana, and Ukraine.
The second wave started in August 2012 and was completed in June 2014. Wave 2 countries are: Armenia, Georgia, Macedonia, and Kenya.
The STEP (Skills Toward Employment and Productivity) Measurement program is the first ever initiative to generate internationally comparable data on skills available in developing countries. The program implements standardized surveys to gather information on the supply and distribution of skills and the demand for skills in labor market of low-income countries.
The uniquely-designed Household Survey includes modules that measure the cognitive skills (reading, writing and numeracy), socio-emotional skills (personality, behavior and preferences) and job-specific skills (subset of transversal skills with direct job relevance) of a representative sample of adults aged 15 to 64 living in urban areas, whether they work or not. The cognitive skills module also incorporates a direct assessment of reading literacy based on the Survey of Adults Skills instruments. Modules also gather information about family, health and language.
Sample survey data [ssd]
The units of analysis are the individual respondents and households. A household roster is undertaken at the start of the survey and the individual respondent is randomly selected among all household members aged 15 to 64 included. The random selection process was designed by the STEP team and compliance with the procedure is carefully monitored during fieldwork.
Version 02, edited anonymous datasets for public distribution.
Version 01 was published in June 2014, but now is replaced with v02.
The difference between v02 and v01 datasets:
The literacy variables had incorrect labelling, which has now been fixed
The 'emp' variable has been cleaned
The 'write_dif' variable has been corrected
All monetary variables (identifiable by '_usd') have been converted to PPP dollars
The scope of the study includes:
household demographic characteristics
dwelling characteristics
education and training
health
employment
job skill requirements
personality, behavior and preferences
language and family background
reading literacy test assessment
The STEP target population is the urban population aged 15 to 64 included. Lao PDR sampled both urban and rural areas (with road) of the country.
Areas are classified as rural or urban based on each country's official definition.
The STEP target population is the population aged 15 to 64 included, living in urban areas, as defined by each country's statistical office.
Are excluded from the sample:
Laos' Target Population Description
The target population comprises all non-institutionalized persons 15 to 64 years of age (inclusive) living in urban and rural areas of the country at the time of data collection. This includes all residents except foreign diplomats and non-nationals working for international organizations. There will be no exclusions for the target population. The survey tool is designed for Lao language only (the sole national language). IRL will make every effort to interview non-Lao speaking persons through the use of local translators. In most such cases, the household and individual modules will be carried out with the assistance of a translator when available. However, Modules 6 and 9 will not be administered to those respondents who do not speak or read Lao as per STEP technical standards.

The Laos sample design is a 3 stage stratified sample design. The stratification variable is urban-rural indicator.
First Stage Sample
The primary sample unit (PSU) is a village. The sampling objective was to conduct interviews in 134 urban villages and 54 rural villages.
The villages were selected with probability proportional to size (PPS), where the measure of size was the number of households in a village.
Second Stage Sample
The second stage sample unit (SSU) is a household. In the second stage, the number of households selected in each selected PSU was proportional to the size of the selected PSUs. The households were selected from a list of households in each selected PSU by systematic equal probability sampling. At the same time, a reserve sample of the same number of households as the target sample in each PSU was selected for use when needed to ensure that the target sample size is achieved.
Third Stage Sample
The third stage sample unit was an individual aged 15-64 (inclusive). The sampling objective was to select one individual with equal probability from each selected household.
An overall response rate of 95% was achieved in the Lao PDR STEP Survey.
The Laos three-stage stratified cluster design resulted in differential probabilities of selection for the selected persons. Consequently, each selected person in the survey does not necessarily represent the same number of persons in the target population. To account for differential probabilities of selection due to the nature of the design and to ensure accurate survey estimates, the Laos STEP requires a sampling weight for each person that participated in the survey.
In general, the objectives of the Laos STEP weighting are to construct a set of survey weights to,
The general weighting procedure for the Laos STEP survey required the following tasks.
The STEP survey instruments include:
All countries adapted and translated both instruments following the STEP Technical Standards: 2 independent translators adapted and translated the Background Questionnaire and Reading Literacy Assessment, while reconciliation was carried out by a third translator.
The WB STEP team and ETS collaborated closely with the Lao PDR survey firm during the process and reviewed the adaptation and translation to Lao using a back translation.
The survey instruments were both piloted as part of the survey pre-test.
The adapted Background Questionnaires are provided in English as external resources. The Reading Literacy Assessment is protected by copyright and will not be published.

Each interviewer team reports to a team supervisor. Interviewers must hand over to their supervisor properly filled questionnaires and reading exercise booklets (for Reading Literacy Assessment), and report all information about the fieldwork conducted.
Team supervisors are responsible for coordinating fieldwork, monitoring interviewers' work, documenting non-response, assigning reading exercise booklets and communicating regularly with a field manager. Also, once the household listing exercise is completed, the team supervisor randomly selects 15 households to be interviewed in the primary sampling unit (PSU), as well as reserve households that may be required to be activated (used) in the case of a non-response by one of the originally selected 15 households.
Field supervision details are outlined in "National Survey Design Planning Report" and "Interviewer's Manual and Team Supervisor's Manual", available in external resources.
Each component of the STEP Survey was carried out by a personal visit using a Paper-and-Pencil Interview (PAPI) method. Interviews lasted between 120 and 150 minutes, depending on respondents' reading proficiency.
As the STEP program requires all surveys to be implemented in a standardized way, particular attention was provided to implementation processes:
Each participating country (survey firm) presented National Survey Design Planning Report (NSDPR) detailing how it intended to implement the STEP survey while complying with the STEP Technical Standards. The NSDPRs were submitted to the WB STEP team for approval.
The World Bank (WB) STEP team and Educational Testing Services (ETS) conducted two workshops for all survey firms. The first was a 2-day workshop provided via video conference and aimed at presenting the STEP Technical Standards. The second workshop was organized over two full weeks at the World Bank Headquarters. During this course project managers from each survey firm received training on the survey instruments, implementation of the survey and data management procedures.
Based on the STEP Technical Standards, the survey firms adapted and translated the STEP survey instruments, the interviewer manual, and all training materials.
Once the instruments had been adapted and translated, survey firms carried out a pre-test, usually including 20-30 interviews. Findings from the pre-test were discussed with the WB STEP team and ETS to finalize the adaptation and translation of the STEP survey instruments. The survey was implemented in Georgian.
Each survey firm provided a 2-week training course to its enumerators, using training materials developed by the WB STEP team (after translation and adaptation). The WB STEP team's survey consultant helped organize the training and was present in the country for the first few days of the training. In addition, the WB STEP team in Washington DC provided just-in-time technical assistance, answering questions sent by the survey firm during the training. The training included in-field mock interviews in addition to in-class courses. At the end of the training, survey firms only retained enumerators having demonstrated a good understanding of the instruments.
As per STEP Technical Standards, data collection started within a few days of the end of the enumerators' training course. The composition of each country's fieldwork teams, reporting procedures and quality control processes are described in the NSDPR. Weekly reports were sent to the WB STEP team, which provided just-in-time technical assistance during fieldwork to answer questions or concerns. Regular calls or VCs were also held between survey firms and the WB STEP team to discuss progress. Matters discussed usually involved questions on how to deal with specific situations, strategies to reduce non-response, the activation of reserve households, and general pace of progress.
STEP data management process:
Detailed information on data processing in STEP surveys is provided in “Guidelines for STEP Data Entry Programs” document, available in external resources. The template do-file used by the STEP team to check raw background questionnaire data is provided as an external resource, too.
A weighting documentation was prepared for each participating country and provides some information on sampling errors.
All country weighting documentations are provided as an external resource.
