This study explores women’s attrition from male-dominated workplaces based on Norwegian public administrative records, covering individuals born 1945–1983, in the period between 2003 and 2013. It examines sex differences in rates of attrition and tests the significance of two commonly proposed explanations in the literature, namely the degree of numerical minority status and motherhood. It also investigates whether these explanations vary by occupational class. Selection into male-dominated workplaces is accounted for by using individual fixed effects models. The results show that attrition rates from male-dominated workplaces are considerably higher among women than among men. Moreover, the risk of female attrition to sex-balanced workplaces increases, regardless of occupational class, with increases in the percentage of males. Childbirth is associated with an increased risk of attrition to female-dominated workplaces, while having young children (⩽ 10 years old) lowered the risk. This association, however, was primarily evident among working-class women in manual occupations.

这项研究根据挪威公共行政记录（涵盖1945-1983年出生的2003年至2013年之间的年龄），探索了女性在男性占主导地位的工作场所中的流失情况。它研究了流失率的性别差异，并测试了两种普遍提出的解释的意义。文献中，即少数族裔的数字地位和母亲身份。它还调查这些解释是否因职业类别而异。使用个体固定效应模型来说明选择男性占主导地位的工作场所。结果表明，男性占主导地位的工作场所的流失率明显高于男性。此外，不论职业类别如何，女性流失到性别平衡的工作场所的风险都会随着男性百分比的增加而增加。分娩与女性占主导地位的工作场所的流失风险增加有关，而年幼的儿童（⩽10岁）则降低了这一风险。但是，这种联系在从事体力劳动的工人阶级妇女中尤为明显。
