In the population projection, the population differentiated by federal states, age, gender and country of birth is projected into the future. Since 2022, the projection is computed as a microsimulation. In order to document the uncertainties of future developments, the population projection is calculated in several scenarios and variants based on different combinations of high, medium and low assumptions for the projection parameters fertility, mortality and migration. The main scenario uses the medium assumption sets and depicts the most probable development path. The rounded results are published as web tables (main scenario for Austria and the federal states as well as alternative scenarios and variants for Austria) and STATcube datasets (all scenarios and variants for Austria and the federal states). The results for the alternative scenarios and variants for the federal states are also available as ods-files upon request. For (model) calculations, the raw data is also available; part of this data is published as a web table. Further raw data can be requested by e-mail.
