In addition to the federal public administration, the AOB also monitors administration of the regional and municipal authorities in seven of the federal Laender. Only the Laender of Tyrol and Vorarlberg have their own regional ombudsman. In 2011, the AOB conducted a total of 2,622 investigative proceedings of regional and municipal government administration. In comparison to the previous year, the number of investigated cases in these sectors has risen by 5.4%. It is not surprising that the most populous Laender, Vienna, Lower Austria and Styria, occupy the top three places with regard to the number of investigative proceedings. In comparison to the previous year, the number of cases rose in Vienna, Upper Austria, Carinthia, Styria and Burgenland, but fell in Lower Austria and Salzburg.
