One of the most important social developments that helped to make possible a shift in thinking about the role of public education was the effect of the baby boom of the 1950's and 1960's on the schools.In the 1920's, but especially in the Depression conditions of the 1930's, the United States experienced a declining birth rate -- every thousand women aged fifteen to forty-four gave birth to about 118 live children in 1920,89.2 in 1930,75.8 in 1936, and 80 in 1940.With the growing prosperity brought on by the Second World War and the economic boom that followed it young people married and established households earlier and began to raise larger families than had their predecessors during the Depression.
一項重要的、有可能促使人們對公共教育的角色的看法發生轉變的社會發展是本世紀五六十年代的生育高峰對學校的影響。在 20 年代,尤其是在 30 年代后的大蕭條中,美國經 歷了一次出生率的下降--1920 年每千名年齡在 15歲至 45 歲的婦女生下大約 118 個存活嬰兒,1930 年 89.2 個,1936 年 75.8 個,1940 年 80 個。隨著二戰帶來的持續繁榮以及隨之而來的經濟增長,年輕人比大蕭條中的同齡人更早地結婚成家,而且比前輩養育更大的家庭。
