Roland Hosner, MA
Survey Statistician
Roland is a quantitative sociologist and migration researcher, working on population and mobility statistics derived from mobile phone data. As our Senior Statistician, he leads all work on survey design and analysis, as well as on data triangulation of mobile phone data, survey and census data and geospatial data to produce mobility and population estimates.
The focus of his work is on estimation approaches and data integration of Big Data and standard data sources, and on statistical quality, particularly the assessment and adjustment of biases.
He has also designed and led our phone surveys in DRC (2021), Ghana (2022) and Haiti (2023), the DRC microcensus in partnership with WorldPop (2021), and all cooperation with existing survey programmes such as REACH Multi-Sector Needs Assessments in Haiti or Ghana Statistical Services Annual Household Income and Expenditure Surveys.
Supporting humanitarian work, development efforts and human rights is the motivation for his career as a researcher, and what brought him to Flowminder. Previously, he has worked for the DeZIM institute in Berlin on irregular migration, for ICMPD in Vienna on refugee surveys and on migration statistics, for KU Leuven on political socialisation, for Statistics Austria on income statistics, for the University of Vienna as a lecturer on social research, and for Amnesty International as campaigner for Individuals at Risk.
