"This essay presents tentative findings for the Sundsvall area of Sweden, which is being studied in a recent project on the decline of infant and childhood mortality in the Nordic countries. The focus is on the complete reproductive histories of single mothers and the life expectancies among infants born to women who at least once in their reproductive life history experienced the birth of an illegitimate child. In Sundsvall, industrialization only temporarily affected the illegitimacy ratio, but its effect was obvious even in agrarian parishes. The number of illegitimate children per woman remained relatively stable over time, with the exception of the town of Sundsvall. It was more common in the urban environment to give birth to several illegitimate children. Mortality was also higher among these infants, but the negative effects can be seen equally among both legitimate and illegitimate children."
本文展示了瑞典松兹瓦尔地区的初步研究结果，该地区正在一项关于北欧国家婴儿及儿童死亡率下降的近期项目中接受研究。重点关注单身母亲的完整生育史，以及在其生育生命历程中至少有一次经历过非婚生育的女性所生孩子的预期寿命。在松兹瓦尔，工业化仅暂时影响了非婚生比率，但其影响即便在农业教区也很明显。每位女性的非婚生子女数量随时间相对保持稳定，但松兹瓦尔镇除外。在城市环境中生育多个非婚生子女更为常见。这些婴儿的死亡率也更高，但在婚生子女和非婚生子女中都能同样看到负面影响。
