Official sector expenditures for the sustenance of refugees in donor countries during the first twelve months of their stay. To improve transparency in members’ reporting of in-donor refugee costs several surveys have been conducted to seek clarifications on the methodologies and calculations used in the reporting of this item. The latest Survey was completed in 2012; its findings relate to 2009 expenditures. Users should be aware that data on in-donor refugee costs are not necessarily comparable between donors as reporting practices vary in terms of categories of refugees included, types of expenditures covered, and methodology used to assess costs during the first year of stay of refugees. In order to facilitate understanding of expenditures included in this item in ODA statistics, summaries of donors’ methodologies have been produced along with a general overview of differences in coverage and methodology (see link for the Survey’s results).
