Tomas Sobotka leads the research group on Fertility and Family and serves as deputy director of the Vienna Institute of Demography (Austrian Academy of Sciences and Wittgenstein Centre). Since 2021 he is Editor-in-Chief of the Vienna Yearbook of Population Research.

His research focuses on global low fertility and family changes, family policies, fertility data and measurement, migration, population and family change in Europe, and assisted reproduction. Tomas has helped launching and expanding several data repositories, including the Human Fertility Database (HFD, www.humanfertility.org), Human Fertility Collection (www.fertilitydata.org) and Cohort Fertility and Education (CFE) database (http://www.cfe-database.org). He is keen on expanding demographic knowledge beyond the boundaries of the discipline. To that aim, he has been collaborating with the United Nations Population Fund (UNFPA) and other organisations, and coordinating the European Demographic Data Sheet (http://www.populationeurope.org) (2018-2022).

In 2017 he was awarded Allianz European Demographer Award and in 2022 the Dirk J. van de Kaa Award for Social Demography awarded by the European Association for Population Studies (EAPS).
