iPhone users have a reputation for being smug – and now they may have a good reason.

使用iPhone的人通常都自命不凡，而如今他们这种心态有了一个更加充分的理由了。

A recent study has found that people who use an iPhone are smarter than those who prefer Android devices.

近日的一项研究发现iPhone用户要比偏爱安卓系统的用户更聪明。

This is based on research that found states with more college graduates also tend to have higher iPhone sales.

这项发现基于这样一个事实：所在州的大学生人数越多，iPhone的销量就越高。

The study, by Massachusetts-based advertising¹ group Chitika, discovered that Alaska, Montana and Vermont have the largest number of iPhone users in the US.

这项马萨诸塞州广告小组所研究的课题发现在美国，阿拉斯加、蒙大纳和佛蒙特三州iPhone的持有者人数最多。

These states also have the highest percentage of college graduates.

而这三个州拥有大学学历的人口所占百分比也是美国国内最高的。

Meanwhile, New Mexico, Iowa and Delaware have the lowest percentage of people who use iPhones, and a lower number of graduates.

与此同时，新墨西哥州、爱荷华州以及特拉华州的iPhone持有者所占比例最低，而这几个州拥有的大学生人数也较少。

As well as intelligence, the research found that wealth was linked to higher iPhone use – a factor that Chitika says is related to education.

除了智力方面的因素外，研究还发现，经济能力更好也与iPhone的使用有关，而这项因素是与受教育程度挂钩的。

The study also found that iPhone sales are linked to population density². The more densely³ populated an area, the more chance iPhone sales will be higher.

这项研究同时发现，iPhone的销量和人口密度有关，人口越是密集的地区，iPhone的销量就有更高的可能。
