Missing Migrants Project data collection guidelines

This  document  defines  the  Missing  Migrants  Project’s  methodological  framework  to  serve  as  a  guide  for  institutions  interested  in  contributing  relevant  data,  such  as  medical  examiners,  police  departments,  immigration  authorities,  as  well  as  non-governmental  actors  working  with  migrants.  For  this  reason,  this  document  provides  background  information  on  IOM’s  Missing  Migrants  Project  data  and  describes  the  definitions and variables used for data collection. The main objective of these guidelines is to improve data collection  within  the  Missing  Migrants  Project  framework  and  thus  to  increase  awareness  about  migrant  fatalities in underreported regions globally.

The guidelines are also available in Spanish and French.

To report an incident involving a migrant death or disappearance for inclusion in the Missing Migrants Project database, please use the following form in English | Spanish | French.
