This report describes efforts to assess the impact of the April 1972 issue of "Social Education," devoted to population education, and the effectiveness of various attempts to enhance the impact of the issue. Assessment was accomplished by a questionnaire administered to randomly chosen groups of members of the National Council for Social Studies. The following items from the questionnaire are discussed in this report: awareness of population education, meaning of the term; determination of whether or not population is taught; allocation of time spent on teaching about population; and attitudes toward population. Questionnaires dealing with the influence of the April issue indicated a greater awareness of the term Population Education and an increased allotment of time spent on population education in the classroom. Questionnaires assessing the impact of the enhancement techniques, which included letters sent to sensitize Council members to the April issue and a mailing of resource materials, revealed little or no impact on the proportion of subscribers who read the issue or on their likelihood of teaching the subject.
