拿到不止一个美国大学OFFER的童鞋们，恭喜你们！但是这人生最宝贵的四年时光，你们到底选择在哪里渡过呢？这可是个问题——以下是来自十万学生的大数据，看看别人家的孩子们是怎么选的！
Parchment公司从104,119位自2012-2013学年起申请大学本科的高中生收集在录取他们的两个或多个学校中选择最终就读学校的统计数据。数据反映了经济学家所谓的显示偏好（revealed preference）理论，学生是如何从两个或更多录取他们的大学中最终决定去哪里就读。
当我们解读这些结果时，必须认识到学生们的就读决定并不是随机形成。在形成其决定的诸多因素之中，像地理位置的远近，学校是否提供州内学费优惠等都起到了相当作用，比方说申请者非常可能偏好选择距离其居住地较近的大学而不是相反。
Parchment的服务通常在某些州使用得比其他州更为广泛，这就意味着对于学校的偏好与随机挑选学生样本的前提条件并不匹配。尽管如此，多数大学所显示的选择就读数据，包括那些全国范围内招生的学校，基本上与其他渠道获取的类似数据相吻合。
哪些地方的学生使用Parchment：
该公司的服务在某些州使用将为广泛，特别是当地政府有项目鼓励使用该服务时。所以以下用户数据样本没有与各州的实际学生数按比例完全对应。数据样本中来自密歇根州、印第安纳州、加利福尼亚州和威斯康星州的学生的比例要比实际占比大一些；而来自德克萨斯州和纽约州的学生比例则比实际要小。
以下数据显示了同时被密歇根大学安娜堡分校和另一学校录取后，被录取学生的择校决定。在下列每一组数据中，首先出现的是与密歇根大学安娜堡分校同时录取某个学生的学校名称；第一个含百分比的数字为这个学生最终选择就读前一行显示学校的比例；第二个数字则为样本学生数量，所有样本包括的学生最终不是选择了密歇根大学安娜堡分校就是选择了每一行出现学校之一就读。以第一行布朗大学为例，在样本为15个同时被布朗大学和密歇根大学安娜堡分校录取的学生中，100%都选择了就读布朗大学，当然没有人也就是0%选择就读密歇根大学安娜堡分校。
