Abstract Demographers have for some time suggested that the cost of children has an important bearing on couples' fertility decisions. Dublin and Lotka, for example, voiced the opinion that 'it is undoubtedly the anticipation of greatly increased expenditures, the sudden demands made on the family exchequer when a child is born and for some time after, that causes people of limited income to restrict the size of their families'. Banks, Myrdal, and Day and Day have echoed this same theme.
摘要 人口统计学家认为，子女的成本对夫妻的生育决策有重要影响。例如，都柏林和洛特卡认为，“毫无疑问，当孩子出生以及出生后一段时间内，家庭财政会突然面临大幅增加的支出，这使得收入有限的人们限制了家庭的规模”。班克斯、米尔达尔、戴和戴也附和了这一主题。
