Final answer:
The most accurate heading for the chart is "Women in the Workforce in Percent," reflecting statistics and societal attitudes towards women's employment post-World War II.
Step-by-step explanation:
The heading that should replace the question mark in the chart below, considering the provided context and resources, would most accurately be “Women in the Workforce in Percent.” This is because the information points to discussing statistics and opinions about women's employment, particularly in the post-World War II era when women were encouraged to leave their jobs for returning servicemen and the prevailing social attitudes towards women working, especially those with husbands capable of supporting them.
During that time, there was a societal expectation that jobs should be reserved for men, particularly those with families to support. A 1946 survey indicated that both men and women largely agreed that an inefficient man with a family should be employed over an efficient woman whose husband could support her. These statistics and attitudes are captured under the broader topic of “Women in the Labor Force,” which would encompass all employed adult women, including those with children.
