The following graphs shows the number and nationality of new members elected at the Shanghai Rotary Club each year between 1919 and 1939. They derive from the list of Rotarian members drawn after the Shanghai Rotary Club handbook (see table: http://madspace.org/cooked/Tables?ID=198).

The first graph reveals a general increase in membership especially at the end of the period, with a peak in 1936 (almost three times the figure of 1935 and more than ten times that of 1919). The second graphs shows the distribution of members according to their nationality. It reveals that the Chinese form the most important group in the Club,(46, 38%), followed by Americans (31, 24%), British (15, 19%), French (6, 4,7%), Japanese and German (4 each) and other European minorities. 

The third graph shows the date of election by nationality. Originally new members were mostly American and British. Yet Chinese members were elected at a very early time (1920). Chinese membership reached a turning point after 1927 (coinciding with the integration of Chinese representatives within the Shanghai Municipal Council). The Rotary Club started to include German, Japanese, Russian and French members in 1927, 1929, 1930 and 1931, respectively. Then we observe a trend towards a diversification of membership. New European minorities (Swiss, Netherlands, Norwegian) became members only at the end of the period (after 1935).
