This set of three maps aims at mapping the workplace of Shanghai Rotarians, according to the class of service to which they belonged (i.e. sector of activity) between 1930 and 1948. The original data come from three successive rosters of members published in 1930, 1940 and 1948. For classifying activities, I relied on a simplified version of the official classification of services that the Rotary International established in the 1920s. I used ArcGis and QGis to process the data and draw the map.
The first map maps the distribution of workplace all services included. The second one maps the activities that were both concentrated and centralized in the Central district of the International Settlement (financial and communciation services; paper, publishing and printing industry; building materials and construction industry; chemical industry; retail and wholesale trade), while the third map visualizes the diverse activities that detracted from this dual pattern of concentration and centralization, with workplaces scattered throughout the foreign settlements (arts and entertainements; associations; education, religion and charity; government sevice; medical and health services; machinery; transportation, shipping and storage; textile industry; food and tobacco industry);
