脸书调查:父母职业对子女择业的影响

你是否怀疑过自己对工作行业的选择受到了父母职业的影响呢?来自脸书的研究者们特地调查了父母与子女的职业选择来找出真相。
在一篇博客中,脸书的研究人员Ismail Onur Filiz和Lada Adamic解释了他们是如何通过筛选脸书上说英语的560万对父子关系以寻找潜在规律的。通过检查对比列出的职业,两位研究者计算出子女从事的职业类型受其父母职业影响的概率。上面这幅图显示了孩子的就业领域跟他们父亲就业领域的关系,当然你可以在他们的脸书博客里看到一系列交互式的视觉化说明。
举个例子,如果父亲是从事律师职业,那么儿子就比普通人高4.6倍的可能性会从事医疗工作。同时,如果母亲是护士,那么女儿就比普通人高3.75倍的可能性从事护理工作。但是值得注意的是其中一些统计方式如果放到格局较大的事物上可能意义并不大,他们解释说:即使相对而言,孩子更有可能从继承他们父母的行业,但是这个绝对百分比却是非常低的。例如,如果父亲在军队里,儿子从军的可能性比一般人要高5倍,但是实际上,在这些父亲是军人的子女中,只有四分之一会从军。再举例而言,在我们的数据中,如果父亲从事农业,渔业或者林业,他们的儿子里只有3%会子承父业,但这也是一般人可能性的7.6倍。如果母亲是职员和行政,她们的女儿中有20%会从事同样的职业,但是这仅仅是一般人可能性的2倍。
如果这个结果看起来太性别化,那是因为这也许是“代际”转变的结果,越来越多的你才行在过去几十年中成为了劳动力。但是研究者同样指出,这些模式如果跟全部人口相比实际上很罕见。而且这里还有着需要注意的地方:比如军队里的人比普通人更倾向于说明自己的职业,而且既然研究仅限于脸书,说明这个结果并不能代表整个社会。
Filiz和Adamic同时还关注了兄弟姐妹的相互影响。如果你们被同样的父母抚养,你应该跟兄弟姐妹有着类似的童年经历,因此你们感兴趣的领域应该差不多,对吗?他们对比了双胞胎和非孪生的兄弟姐妹。结果发现兄弟姐妹之间的影响非常明显:15%的兄弟姐妹从事了同样的工作;在双胞胎中,这一数字是24.7%。对比之下,在美国,同样性别和年龄的人从事同一职业的可能性是8.6%。

How Your Parents' Career Choices Affect Your Own, Visualized

How Your Parents' Career Choices Affect Your Own, Visualized

Ever wondered if your choice of job was influenced by what your parents did for a living? Well, researchers at Facebook have taken a look at parent-child profession choices to find out.

In a blog post, Facebook research staff Ismail Onur Filiz and Lada Adamicexplain how they’ve sifted through 5.6 million parent-child pairs in the English-speaking Facebook world to identify some trends. By examining listed occupations, the pair were able to calculate the probability of a child having an occupation given their parent’s occupation. The image above shows how a son’s employment relates to that of their father, but you can explore way more in a series of interactive visualizations over on the Facebook blog.

As an example, the son of a father who works in the legal profession is 4.6 times as likely to practice medicine than the average. Meanwhile, daughters whose mothers are nurses are 3.75 times more likely to enter nursing than the average. But it’s worth bearing in mind that some of these statistical quirks may not mean much in the grander scheme of things, as the pair explains:

Even though relatively speaking, a child may be much more likely to follow in his or her parents’ footsteps, the absolute percentage may still be quite low. A son who has a father in the military is 5 times more likely to enter the military, but just 1 in 4 sons of a military professional does so. For fathers in the dataset who work in farming, fishing and forestry, only 3% of their sons stay in the profession, but this probability is 7.6 times the overall rate. 20% of daughters of mothers who work in office and administrative support choose the same career, but this is only 2x the usual rate.

There’s clearly way to much data here to describe it all, so it’s worthheading to the page to check out what you’re interested in looking at.
