Profile of Internally Displaced Persons in North-East Nigeria 2018
The Nigeria IDP Survey was conducted in IDP camps and host communities in the Northeast regions of Nigeria. The survey was used to compile a socio-economic profile of IDPs and host communities to help inform durable solutions to internal displacement. The survey contains information on poverty, education, service access, employment and livelihoods, as well as perceptions. The data combines detailed household information with displacement-specific information including drivers of displacement, access to resettlement mechanisms, and return intentions. It also includes comprehensive information on assets and consumption, to allow estimation of poverty based on the Rapid Consumption methodology.
Kind of data
Sample survey data [ssd]
The survey covered IDPs in camps, IDPs in host communities, and host communities in six states in Northeast Nigeria. The six states are Adamawa, Bauchi, Borno, Gombe, Taraba, and Yobe. The survey thus represents IDPs (in camps and in host communities)) and host communities of Northeast Nigeria.

The Nigeria IDP Survey is a household survey with a multi-stage stratified random sample. Six Northeastern states were covered: Adamawa, Bauchi, Borno, Gombe, Taraba, and Yobe. The sampling frame consisted of a list of wards with IDP household counts in the six states, provided by the International Organization for Migration (IOM) Displacement Tracking Matrix (DTM) 2017.
The sample had 6 strata with each state as a stratum. Each stratum was divided into grids of 150 by 150 meters using GIS technology defining the enumeration areas (EAs). The number of EAs to be selected from each stratum was obtained proportional to the IDP population sizes in each state.
For the IDP sample, the EAs consisted of two types of IDP settlements, which were host community settings and camp settings. A total of 111 EAs across the 6 states were randomly selected proportional to size. Out of these, 77 EAs were host community type EAs and 48 were camp-like EAs.
For the host community sample of 1,500 households, EAs were restricted to the 77 host community type EAs that were selected based on IDPs population numbers, in the absence of residential population estimates at this level. The survey is representative for IDPs and host communities, defining host communities as the non-displaced population living in the EAs with displaced populations.
All the households in the selected EAs were first listed, and 12 IDP households and 12 (or multiples of it) host community households were randomly selected and surveyed per EA, to reach the designated sample size.
Deviations from sample design
Certain adaptations had to be made during the listing and survey period. Households with duplicate names and contact numbers and households outside the cluster boundaries were dropped. A few EAs also had to be dropped from the sampling due to insecurity or – in occasional cases – due to unreachability due to inclement weather over prolonged periods of time. While EAs were initially replaced at the beginning of the survey, new replacements were avoided at the end of the survey duration to avoid extended field work time due to cost implications.
The sampling weight is the inverse probability of selection. The selection probability for a household can be decomposed into the selection probability of the EA within the stratum, and the selection probability of the household within the EA. The first-stage probability of selection for the EA is the same for the IDP and host community households. It is equal to the IDP population of the EA divided by the total number of IDPs in the stratum multiplied by the number of selected EAs in the stratum. For IDPs, the second-stage probability of selection is the number of selected IDP households per EA divided by the number of listed IDP households in the EA. For host community households, the second-stage selection probability is the number of host community households selected per EA divided by the number of listed host community households in the EA.
