In this interview, Irina Mützelburg discusses the production and spreading of humanitarian numbers in the on-going Russian–Ukrainian war since February 2022. She traces the emergence of the announced number of Ukrainian refugees several months before the beginning of the full-scale invasion and analyses the ways in which the United Nations High Commissioner for Refugees (UNHCR) and the International Organization for Migration (IOM) compile statistics respectively on Ukrainian refugees abroad and internally displaced persons (IDPs). Numbers are produced to be coherent and higher, to illustrate the need for attention and funding. Furthermore, the debated issue of Ukrainians who (were) moved to Russia since the invasion is reviewed, discussing not only the numbers, but also the ways the Ukrainian and the Russian states frame the ways and reasons for which Ukrainians came to Russia. Finally, the interview covers the term ‘evacuee’ and ‘evacuation’ that both Russian and Ukrainian politicians and media use in unusual ways and which have been taken up by international media outlets.
