National Survey on Population and Employment, ENPE 2013
Labor Force Survey [hh/lfs]
The National Institute of statistics (INS) in Tunisia started by collecting the first bi-annual National Survey on Population and Employment in 1997. Annual surveys started to be collected since 2000.
In 2004, methodologies of both the General Census of Population and Housing and the National Survey on Population and Employment Survey were harmonized with the concepts of the International Labour Organization (ILO).
Later in 2011, INS started to conduct the ENPE quarterly.
THE CLEANED AND HARMONIZED VERSION OF THE SURVEY DATA PRODUCED AND PUBLISHED BY THE ECONOMIC RESEARCH FORUM REPRESENTS 100% OF THE ORIGINAL SURVEY DATA COLLECTED BY THE NATIONAL INSTITUTE OF STATISTICS (INS) - TUNISIA
The survey aims at estimating the demographic and educational characteristics of the population. It also calculates the economic indicators of the population such as the number of active individuals, the additional demand for jobs, the number of employed and their characteristics, the number of jobs created, the characteristics of the unemployed and the unemployment rate.
Furthermore, this survey estimates these indicators on the household level and their living conditions.
The results of this survey were compared with the results of the second quarter of the national survey on population and employment 2011. It should also be noted that the National Institute of Statistics -Tunisia uses the unemployment definition and concepts adopted by the International Labour Organization. This definition implies that, the individual did not work during the week preceding the day of the interview, was looking for a job in the month preceding the date of the interview, is available to work within two weeks after the day of the interview.
In 2010, the National Institute of Statistics has adopted a strict ILO definition for unemployment, by conditioning that the person must perform effective approaches to search for a job in the month preceding the day of the interview.

Unit of Analysis
V1: A cleaned and a harmonized version of the survey dataset, produced by the Economic Research Forum for dissemination.
All documentation available for the original survey provided by the Statistical Agency, and for the harmonized datasets produced by the Economic Research Forum, are published, along with a copy of all occupation and economic activity classifications used during the harmonization process.
However, as far as the datasets are concerned, the Economic Research Forum produces and releases only the harmonized versions in both SPSS and STATA formats.
Household: Includes geographical characteristics, household composition, LFS classification of household members, head's and spouse's characteristics, dwelling characteristics and ownership of durables.
Individual: Includes demographics, nationality and immigration, education, current labor status, main, secondary and last held job characteristics, wages and incomes, unemployment characteristics and inactivity reason(s).

Dates of Data Collection
Data Collection Mode
The control and supervision of the work of interviewers was achieved over several steps, in fact interviewers are divided into teams of three or four headed by a supervisor.
The supervisor ensures that the interviewers locate and correctly identify the limits of the clusters, conduct the interview properly, when it comes to the way the interviewer asks the questions and efficiently completes the questionnaire.
Once completed, questionnaires are then submitted to regional offices. The office auditor checks the questionnaires for errors, inconsistencies or omissions.
These teams of interviewers and auditors are supervised by a supervisor for each governorate (or all governorates). The supervisor, ensures the smooth coordination between different teams and the smooth flow of information from the central to regional offices. The supervisor is also responsible for the training of interviewers and auditors before the interviews start.
National Institute of Statistics
Three modules were designed for data collection:
- Household Questionnaire (Module 1):
Includes questions regarding household characteristics, living conditions, individuals and their demographic, educational and economic characteristics. This module also provides information on internal and external migration.
- Active Employed Questionnaire (Module 2):
Includes questions regarding the characteristics of the employed individuals as occupation, industry and wages for employees.
- Active Unemployed Questionnaire (Module 3):
Includes questions regarding the characteristics of the unemployed as unemployment duration, the last occupation, activity, and the number of days worked during the last year...etc.
- SPSS software is used to clean and harmonize the datasets.
- The harmonization process starts with cleaning all raw data files received from the Statistical Agency.
- Cleaned data files are then all merged to produce one data file on the individual level containing all variables subject to harmonization.
- A country-specific program is generated for each dataset to generate/ compute/ recode/ rename/ format/ label harmonized variables.
- A post-harmonization cleaning process is then conducted on the data.
- Harmonized data is saved on the household as well as the individual level, in SPSS and converted to STATA format.
