Final answer:
The statement that women's clubs were mainly made up of immigrant women is false; they were predominantly composed of white, middle-class, native women who became engaged in community issues and organizations like the National Association of Colored Women's Clubs.
Step-by-step explanation:
The statement that women's clubs were mainly made up of immigrant women is false. Women's clubs, especially in the late 19th and early 20th centuries, were often made up of middle-class women who were predominantly white, native to the country, and not immigrants. Organizations like the National Association of Colored Women's Clubs and the Women's Christian Temperance Union included women who were engaged in community issues, as more women acquired formal education and entered the workforce. Immigrant women typically had more limited access to political power and involvement in such organizations compared to their white, middle-class counterparts.
A historical example can be seen through the postcard 'The Club Woman' from 1905, indicating the demographic that most often participated in these clubs.
