To monitor and report on displacement associated with conflict and violence, we collect data on the countries affected and present nationally aggregated figures for: || New incidents of displacement from 1 January to 31 December 2016 || IDPs who returned, integrated locally or settled elsewhere between the same dates, and when available, for those who crossed an international border and those who were born or died in displacement || The total number of IDPs as of 31 December 2016 We use an event-based methodology to estimate the number of people displaced by disasters during the course of the year, and derive aggregated figures for new displacement for each of the countries affected. We have monitored displacement associated with conflict and violence since 1998 and that associated with disasters since 2008. We have continuously sought to improve the ways we collect and analyse our data, and over the past nine years we have successfully obtained data on ever larger numbers of new displacement events associated with disasters, accounting for more small to medium-sized events than in previous years (see table A.1). Reporting on these events helps paint a more comprehensive picture in terms of the number of people displaced globally. It also provides an empirical evidence base with which to understand them and how they differ from mega-events. Relating others’ data to IDMC’s data model In order to obtain a comprehensive and accurate picture about the scope and scale of displacement at any given point in time, we have generated a unique data model (see figure A.1). One of the challenges we face in producing our figures is relating our partners’ primary and secondary data to it. In order to account comprehensively for the number of people displaced in a given situation, we would have to populate each component of the model, updating the information as quickly as the situation evolved. We are currently working with partners such as IOM, OCHA and UNHCR to do just that, in an effort to better reflect the dynamics of displacement. The purpose of our data model is to better capture all incidents of new displacement, or “flows”, during the year as information becomes available, the number of IDPs reported to have found durable solutions or to have crossed an international border, the number of children born in displacement and the number of IDPs who have died. Figure A.1: IDMC’s displacement data model IDPs settled elsewhere Failed settlement elsewhere Settlement elsewhere Returns Table A.1 Categories of events by magnitude Event size Number of people displaced Small to medium Fewer than 100,000 Large 100,000 to 999,999 Very large One to three million Mega More than three million Internal displacement Children born to IDPs IDPs (includes secondary and tertiary displacement) Failed returns / returnee displacement Local integration Failed local integration Deaths Cross-border flight Returnees Locally integrated IDPs Cross-border return to displacement People displaced across borders (e.g. refugees) As a result of ongoing methodological improvements, including the way partners collect data and the standardised application of the rules and criteria used to analyse displacement associated with conflict, comparisons between countries are now more valid than before.
