Monitoring internal displacement worldwide is at the very heart of what we do and it is the foundation for all our analysis and policy influencing work.
We monitor situations of displacement caused by conflict and violence, disasters and development – globally.
Working closely with partners on the ground, we obtain data on the scale, scope, patterns of displacement. We try to identify new incidents of displacement and monitor how those situations evolve over time.
When possible, we collect data on the age, sex and location of internally displaced people, as well as their shelter type and the duration of their displacement. We even aim to identify when and how many internally displaced people cross borders and how many refugees become internally displaced when they return or are deported back to their country of origin.
In 2016, we obtained conflict-related displacement data for 56 countries and territories and disaster-related displacement data for 118 countries. Our full data set, which stretches back several years, includes 178 countries and territories – and the list is growing as we improve the scope of our monitoring through the use of new tools and approaches.
All of our displacement data is available in our online open data platform, the Global Internal Displacement Database (GIDD).
This is where we capture data from sources and partners and map it onto our internal displacement data model using a consistent set of decision rules and analytical criteria. These rules are transparently documented and made publicly available so that users can understand all of the assumptions, caveats and limitations related to published displacement estimates.

Some of the ways we're working to enhance our monitoring is by using risk modelling, embracing innovation and developing a displacement severity index.
