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.
Kind of data
Sample survey data [ssd]
Version 02, edited anonymous datasets for public distribution.
Version 01 was published in June 2014, but is now replaced with v02.
The difference between v02 and v01 datasets:
- Changes made to all STEP countries:
1) The literacy variables had incorrect labelling, which has now been fixed
2) The 'emp' variable has been cleaned
3) The 'write_dif' variable has been corrected
4) All monetary variables (identifiable by '_usd') have been converted to PPP dollars
- The STEP target population is the urban population aged 15 to 64 (inclusive).
Cities and core urban areas
Unit of analysis
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.
The target population is defined as all non-institutionalized persons aged 15 to 64 (inclusive) living in private dwellings in the urban areas of the country at the time of the data collection. This includes all residents, except foreign diplomats and non-nationals working for international organizations
The following are considered "institutionalized" and excluded from the STEP survey:
- Residents of institutions (prisons, hospitals, etc)
- Residents of senior homes and hospices
- Residents of other group dwellings such as college dormitories, halfway homes, workers' quarters, etc
Other acceptable exclusions are:
- Persons living outside the country at the time of data collection, e.g., students at foreign universities
Deviation Requested from the Standard: The statistical population is composed of core urban households and excludes the categories identified here, as well as itinerants (as classified in the Population Census 2009 in Kenya).

Designed the Reading Literacy Assessment Module and conducted the preliminary analysis of the reading literacy data, including generating plausible values for the Extended Assessment
The sample size was 3894 households. The Kenya sample design is a stratified 3 stage sample design. The sample was stratified by 4 geographic areas: 1-Nairobi, 2-Other Large Cities (over 100,000 households), 3- Medium cities (60,000 to 100,000 HHs), and 4-Other Urban Areas. For detailed description of the sample design and sampling methodologies, refer to Part 3 of the National Survey Design Planning Report (NSDPR) as well as the STEP Survey Weighting Procedures Summary. Both documents are provided as external resources.
Deviations from sample design
War marred and unstable regions of Kenya were excluded from the survey. Itinerants (as classified in the Population Census 2009 in Kenya) were also excluded.
An overall response rate of 91.8% was achieved in the Kenya STEP Survey. Table 21 of the STEP Survey Weighting Procedures Summary provides the detailed percentage distribution by final status code.
The weighting was carried out by the STEP Survey Methodologist. The weighting process is outlined in section 3.7 of the STEP NSDPR for Kenya as well as the STEP Survey Weighting Procedures Summary. Both documents are provided as external resources.
Dates of collection
Mode of data collection
Data collection supervision
The STEP Consortium provided the survey fiirm with a techical standards for field supervision and the STEP Consortium also monitored the fieldwork (see National Survey Design Planning Report (NSDPR) sections 5 and 6 for more details).
The STEP survey instruments include:
(i) A Background Questionnaire developed by the WB STEP team.
(ii) A Reading Literacy Assessment developed by Educational Testing Services (ETS).
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. In Kenya the section of the questionnaire assessing behavior and personality traits (Module 6) was translated into Swahili to adapt to respondents' language preferences, so that the respondent could choose to answer in either English or Swahili.
- The survey instruments were both piloted as part of the survey pretest.
- The adapted Background Questionnaires are provided in English as external resources. The Reading Literacy Assessment is protected by copyright and will not be published.
Étude Économique Conseil Inc.
EEC Canada Inc. was responsible for data entry and processing.
The STEP Data management process is as follows:
1. Raw data is sent by the survey firm
2. The WB STEP team runs data checks on the Background Questionnaire data.
- ETS runs data checks on the Reading Literacy Assessment data.
- Comments and questions are sent back to the survey firm.
3. The survey firm reviews comments and questions. When a data entry error is identified, the survey firm corrects the data.
4. The WB STEP team and ETS check the data files are clean. This might require additional iterations with the survey firm.
5. Once the data has been checked and cleaned, the WB STEP team computes the weights. Weights are computed by the STEP team to ensure consistency across sampling methodologies.
6. ETS scales the Reading Literacy Assessment data.
7. The WB STEP team merges the Background Questionnaire data with the Reading Literacy Assessment data and computes derived variables.
