Tomas Sobotka leads the research group on Fertility and Population Change and serves as deputy director of the Vienna Institute of Demography of the Austrian Academy of Sciences. He is Editor-in-Chief of the Vienna Yearbook of Population Research and co-director of the Human Fertility Database. Sobotka received PhD from demography at the University of Groningen (NL) and lectures at the Charles University in Prague (Czechia) and at the University of Vienna.

His research focuses on global low fertility and family changes, family policies, fertility data and measurement, childlessness, migration, population and family change in Europe, and assisted reproduction. Tomas Sobotka has helped launching and expanding several data repositories, including the Human Fertility Database (HFD, www.humanfertility.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 ).

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