Youths of a country seem to be less interested in going abroad when the per capita GDP of the country reaches a certain level. This education abroad and income paradox is supported by data from a number of countries/regions whose education abroad numbers have peaked. A rough value of $30,000 US in per capita income in purchasing power parity terms seems to be the threshold for a country's interests in education abroad to decline. If confirmed, this per capita GDP threshold can be used as a numerical tool to forecast the future supply of international students in different source countries.

海外教育与收入悖论：研究笔记

当一个国家的人均 GDP 达到一定水平时，该国的年轻人似乎对出国的兴趣降低。这种出国留学和收入悖论得到了来自许多国家/地区的数据的支持，这些国家的出国留学人数已经达到顶峰。按购买力平价计算，人均收入的粗略价值为 30,000 美元，这似乎是一个国家在海外教育方面的兴趣下降的门槛。如果得到确认，这个人均 GDP 阈值可以用作数字工具，用于预测不同来源国国际学生的未来供应。
