Relying on three rosters of members published in 1930, 1940 and 1948, the following graphs aim at mapping Rotarians' offices and residences in Shanghai over the period 1930-1948, all nationalities included (graphs 1 and 2), and according to their nationality (Chinese: graph 3, American : graph 4, British : graph 5).
