UNHCR conducts socio-economic assessments of persons-of-concern (i.e. refugees, asylum-seekers, IDPs, etc.) in a variety of countries in order to inform and improve its programming with the goal of promoting self-reliance. While these assessments are not fully standardized and are tailored to their specific country context, the quantitative surveys share strong similarities in their design and objectives, and are therefore considered a survey series for the purpose of microdata documentation/archiving.
The long-term presence of refugees in Chad and the reduction in funding to provide assistance in recent years have led the humanitarian community to reconsider the approach to assistance of these populations. WFP and UNHCR, the Government's main partners in providing assistance to refugees, had conducted a "socio-economic categorization" in 2014 and 2015 in some refugee camps, and an update was decided for 2017. This update was designed to go beyond a simple categorization and focuses on identifying profiles of refugee households that can be empowered in the short to medium term and the factors that can foster this empowerment. The assessment covers 87,724 refugee households in Chad and was carried out during June-August 2017.

The survey's objective was to deliver representative data of all refugees living in Chad. The total population of refugees at the time of the survey was estimated at slightly below 90,000 households. These refugees were located in 19 refugee camps and 9 villages.
The survey applied a full-coverage (census) approach, i.e. no sample selection was made. The registration database served as the list frame. The total number of completed interviews was 87,724 households.
While the original data collection took a full-coverage approach, the public-release version of the dataset contains a systematically drawn sub-sample of this original data for reasons of statistical disclosure control. The total sample size in the dataset presented for public release is 8,772 households.
Deviations from the Sample Design
This dataset is self-weighting. Nevertheless, since the dataset presented here for public release contains only a sub-sample of the original data (see above), a uniform weights variable is provided in the data.
All questionaires are provided in section "external ressources".

Data was collected through computer-assisted face-to-face interviewing (on smartphones) by 435 enumerators.
The dataset presented here has undergone light checking, cleaning and restructuring (data may still contain errors) as well as anonymization (includes removal of direct identifiers and sensitive variables, and grouping values of select variables). Moreover, it constitutes a sub-sample of the data originally collected.
