A Disadvantaged Start Hurts Boys More Than Girls

Boys are falling behind. They graduate from high school and attend college at lower rates than girls and are more likely to get in trouble, which can hurt them when they enter the job market. This gender gap exists across the United States, but it is bigger for poor people and black people. As society becomes more unequal, it seems, it hurts boys more.


New research from social scientists offers one explanation: Boys are more sensitive than girls to disadvantage. Any disadvantage, like growing up in poverty, in a bad neighborhood or without a father, takes more of a toll on boys than on their sisters. That realization could be a starting point for educators, parents and policymakers who are trying to figure out how to help boys — particularly those from black, Latino and immigrant families.


“It's something about family disadvantage itself,” said David Figlio, a Northwestern University economist and co-author of a new paper, presented publicly for the first time on Thursday. “Black people in America are more disadvantaged than white people in America, and if we were to reduce the disadvantage, we may see a reduction in the relative gender gap as well.”

“这是由于家庭本身的不利因素,”西北大学(Northwestern University)的经济学家戴维·费利奥(David Figlio)说,他是周四首次公开发表的新论文的共同作者。“在美国,黑人相比白人要处于弱势,如果我们减轻这种弱势,相对的性别差异亦可能减少。”

Marianne Bertrand, an economist at University of Chicago who with Jessica Pan has studied the gender gap, also found that boys fare worse than girls in disadvantaged homes, and are more responsive than girls to parental time and resources. “Their findings were very consistent: Families that invest more in children are protective for boys,” she said.

芝加哥大学(University of Chicago)玛丽安·伯特兰德(Marianne Bertrand)和杰西卡·潘(Jessica Pan)一起研究这种性别差异,她亦发现相比起女孩,男孩在弱势家庭中进展得较差,亦较容易受与父母的时间和资源投入的影响。“他们的研究结果与我们一致:在孩子身上作更多投资的家庭能保护好男孩,”她说。

The reasons that boys react more negatively to disadvantage are varied and hard to pinpoint. Even in utero, boys are more sensitive to extreme stress than girls, and tend to have more unruly temperaments. Society discourages boys from showing vulnerability. Low-income families are often led by single mothers, which has been found to affect boys differently than girls.


By the time boys from poor neighborhoods start kindergarten, they are already less prepared than their sisters. The gap keeps widening: They are more likely to be suspended, skip school, perform poorly on standardized tests, drop out of high school, commit crimes as juveniles and have behavioral or learning disabilities.


Boys tend to have more discipline problems than girls overall. But the difference is much bigger for black and Latino children — and more than half of the difference is because of poverty and related problems, the researchers found. For instance, while boys in well-off families have almost the same test scores as their sisters, the gap is more than three times as large in the most disadvantaged families, the study found. While well-off boys are 3.1 percentage points less likely than their sisters to be ready for kindergarten, the most disadvantaged boys are 8.5 percentage points less likely.


The pattern is clear at Astor School, a kindergarten through eighth-grade public school in a low-income part of Portland, Oregon. More than half the students are economically disadvantaged, and nearly half are minorities.

在俄勒冈州波特兰一个低收入地区,设有从幼儿园到八年级的亚斯特学校(Astor School)中便能明显地看到这一规律。该校过半数学生有经济困难,将近一半学生是少数族裔。

Girls generally enter kindergarten with skills suited to doing well in school, like sitting still and using a pencil, while many boys act younger, having trouble listening to adults and controlling their impulses, said Jeff Knoblich, the school counselor.

学校辅导员杰夫·克诺布里希(Jeff Knoblich)指,在进幼儿园时,女孩通常已有在学校表现好所需的技能,如安静坐着和使用铅笔,而多数男孩则表现得较幼稚,在聆听成人说话和抑制冲动方面有问题。

“Boys get a message from a very young age to be a man, and to be a man means you're strong and you don't cry and you don't show your emotions,” he said. “I see boys suffering because of that, and a lot of that comes out in aggressive behaviors.”


Problems in elementary school have long-term effects. Early suspensions are strongly correlated with not graduating from high school. The modern economy relies on skills like cooperation, empathy and resilience — and many boys are entering the workforce poorly equipped to compete.


The researchers — who also included David Autor and Melanie Wasserman of MIT, Krzysztof Karbownik of Northwestern and Jeffrey Roth of the University of Florida — examined various reasons boys could be falling behind. By analyzing brothers and sisters in about 150,000 households using databases from the health and education departments in Florida, they could control for differences in families.

研究人员——包括麻省理工学院的戴维·奧特(David Autor)和梅兰妮·瓦瑟曼(Melanie Wasserman)、美国西北大学的克日什托夫·卡波夫尼克(Krzysztof Karbownik)和佛罗里达大学的杰弗里·罗斯(Jeffrey Roth )——检查了各种会导致男孩落后的原因。通过分析约15万个家庭中兄弟姐妹的数据,他们可以对比在不同家庭之间的差异。数据由佛罗里达州卫生和教育部门提供。

They concluded that boys aren't born this way. Babies of low-income mothers are less healthy, but the boys are not worse off than the girls.


Though disadvantaged children are likelier to be in underperforming schools or neighborhoods with drugs and violence, this alone does not explain the gender gap, the researchers said. Even in the same neighborhood and schools and for children of the same race, the gender gap is wider in less-advantaged families.


“Boys particularly seem to benefit more from being in a married household or committed household — with the time, attention and income that brings,” Autor said.


The researchers compared families based on whether the parents were single or coupled, the education level of the mother, income of the neighborhood and quality of the school. They said they could not isolate which variable mattered most, probably because they are all intertwined.


But they said there were clues to why boys are extra sensitive to disadvantage. A big one is that impoverished households are more likely to be led by single mothers, and boys suffer from a lack of male role models.


Mothers, especially single mothers, tend to spend more time with daughters than sons. Boys, meanwhile, might need more oversight and discipline to learn things like controlling their emotions and focusing on school.


For policymakers, Figlio said, the study's results show disadvantage should be taken into account when devising ways to help boys, and gender should be considered when helping poor children, since boys and girls seem to respond differently.


For educators, research points to the importance for boys of early interventions, like high-quality preschool and mentoring.


For parents, the data shows the payoffs of spending more time with children, especially boys, Bertrand said. For single parents, supporting their families on one income, that might be easier said than done.
