Based on Lillian’s (2008) and Chen’s (2016) studies on women’s courtesy titles, this study makes a comparison and contrast of women’s courtesy titles in mainland China and Taiwan, with reference to those in the Whites and Blacks. It is based on a survey of a questionnaire, which is almost the same as the one used in Chen (2016) that was modelled on the one used in Lillian (2008). The results confirmed that age is an influential factor in the selection of courtesy titles for women of different marital status. It also confirmed Lillian’s observation that a woman’s occupational status may outweigh her marital status. However, even mainland China and Taiwan belong to the same Chinese community, they have statistically significant difference in women’s courtesy titles, especially in the use of XJ (Miss). Its fill-in-the-blank method of collecting women’s courtesy titles, rather than fixed-choices method, also seems to be effective.
