Berlin-Brandenburg was more than 30% higher than the Reich average. In agrarian East Prussia, average earnings were only 814 Reichsmarks, more than 30% below the Reich average. Industrial areas such as Westphalia and the Rhineland were roughly in line with the German average. Despite the efforts of the Prussian government in areas such as education, upward mobility remained limited. In 1927/28, only one percent of junior lawyers came from working-class families. Advancement opportunities were significantly better from primary schools. The proportion of students from working-class families at educational academies rose from 7 percent in 1928/29 to 10 percent in 1932/33. State and administration Administrative divisions The Free State consisted of twelve provinces plus Berlin, whose status corresponded to that of a province. The Hohenzollern Lands in southern Germany were a unique type of administrative district () that was not a true province but that had almost all the rights of one. The provinces were headed by governors () appointed by the Ministry of State. There was in addition a provincial council consisting of the governor, a member appointed by the Minister of the Interior and five members elected by the provincial committee. The provinces each had a parliament. In Hesse-Nassau, municipal parliaments existed for the district associations alongside the provincial parliament. The provincial parliaments elected a who headed the governmental administration; the corresponding office in Berlin was the mayor. In addition, the provincial parliament elected a provincial committee from its own ranks to manage day-to-day business. The provincial parliaments sent representatives to the national-level Reichsrat and the corresponding Prussian Council of State (). Below the provincial level there were (as of 1933) 34 administrative districts; some provinces, including Posen-West Prussia, Upper Silesia, Schleswig-Holstein and also Berlin, had just a single administrative district. A total of 361 districts (called or ) formed the basis of state administration in rural areas and small towns. Larger cities generally formed urban districts (), of which there were a total of 116. While there were only five urban districts in agrarian East Prussia, there were 21 in industrial Westphalia.
