ABSTRACT
This chapter discusses some practical issues related to the collection of data in humanitarian contexts, and the assessment of its reliability and validity. Since space limitations prohibit an extensive treatment of these methodological issues in this book, this chapter can only provide a fairly brief and superficial sketch of some of the most important issues. The interested reader may consult the relevant literature for more detailed introductions. There are many excellent text-books and guides on these topics, e.g. Bernard (2011).
