Tunisia - Labor Market Panel Survey, TLMPS 2014
Data Collection Dates
Data Collection ModeFace-to-face [f2f]
An important aspect of data collection was the use of tablets and digitized versions of the questionnaires. These digitized questionnaires were produced using software tailored specifically for this project. For INS, this was a major innovation and the first time tablets rather than paper questionnaires were used to record data in a household survey. A number of challenges in the fielding and data processing stages, which we discuss below, arose from the process of transitioning from a paper to digital questionnaire model. Prior to data collection, the software and the questionnaires were tested. The pre-test was conducted over a period of three days in the governorate of Ben Arous, and covered about 100 households.
For the purpose of fieldwork, 25 teams were appointed by INS from its own field staff. Each team was composed of three interviewers and one supervisor. A training session, which lasted 10 days, was organized in advance of fielding. This session included Tunisian ERF members in charge of the project, INS staff, and an expert from the Egyptian Central Agency for Public Mobilization and Statistics (CAPMAS), the fielding partner for the ELMPS. As part of the training, enumerators received a manual with detailed information on the questions and the design of the questionnaire. During the training, all the trainees had to implement applied exercises, partly using the tablets, to familiarize themselves with the new digitized data collection process.
Fieldwork started in February of 2014, and the majority of it was completed within one month. However, due to difficulties in getting households to respond in certain areas, and the need to pause fielding while the Tunisian Population Census was underway, fieldwork continued until November of 2014. Further, due to problems in fielding, a number of households from the initial fielding were recontacted by phone in the spring of 2015 to complete their interviews. Given the length of the questionnaire and because of the need to interview the individual him or herself, quite often more than one interview session was needed per household. Once the data were collected, they were transmitted daily, and stored in central servers. The different questionnaires were saved as different files and linked in central processing based on household identifiers .
