The measurement of response burden started in 2001. Since then, Statistics Austria has succeeded in reducing the time required by Austrian enterprises to complete the questionnaires by 13.2 % - despite the fact that additional surveys have been included since 2001. In 2023, 51 686 companies out of a total of around 488 000 companies were required to report to one or more Statistics Austria surveys, 1 489 more than in the previous year. Small businesses are predominantly released from reporting obligations because of cut-off values. Therefore, response burden is concentrated for larger enterprises. 54.6 % of all enterprises with reporting obligations had reporting obligations for one survey only, 26.5 % for two and 18.9 % for three or more. The time required by Austrian companies to fill in the questionnaires from Statistics Austria was around 747 837 hours in 2023 and thus around 2.1 % above the value of 2022.
