Types of employment were becoming more modern, shifting gradually but noticeably towards industry and services. Before World War I, in 1907, 54.9% of German workers were manual labourers. This dropped to 50.1% by 1925. Office workers, managers, and bureaucrats increased their share of the labour market from 10.3% to 17% over the same period. Germany was slowly becoming more urban and middle class. Still, by 1925, only a third of Germans lived in large cities; the other two-thirds of the population lived in the smaller towns or in rural areas. The total population of Germany rose from 62.4 million in 1920 to 65.2 million in 1933.
