日本理科生薪水高過文科生

Recently the Yomiuri News reported the following:

大学の理系学部卒業者の平均年収は、文系学部卒業者に比べて約１００万円高く、年齢が上がるにつれて所得差が広がるという結果が、京都大、同志社大などによるインターネット調査で明らかになった。

　京大経済研究所の西村和雄・特任教授は「文系卒の方が高所得だとの説が一部にあったが、異なる結果になった。理系は技術を身につけることで、より広い範囲の職業を選べることが理由の一つでは」としている。
　２００８年６月、民間調査会社のモニターのうち大卒者から回答を得る方法で実施。１００を超える国公私立大を卒業した２０歳代～６０歳代の１６３２人（文系９８８人、理系６４４人）の回答を分析した結果、平均年収は文系が５８３万円だったのに対し、理系は６８１万円と大幅に上回った。
　年齢別にみると、２５歳の時点では文系が３０６万円、理系が３６６万円で６０万円の差だが、６０歳では文系が７２０万円、理系が８８８万円となり、１６８万円の差に広がった。入学難易度を偏差値から３段階に分けた場合でみても、各難易度で理系が文系を上回った。
　結果の分析や論文作成などを終えたことから発表した。西村特任教授らによると、十数年前に１大学の卒業生を調査し、「生涯所得は文系卒が約５０００万円高い」との研究結果が出されていたという。

The Internet research result of the Kyoto University, and the Doshisha University etc. showed that the average annual salary income of science course faculty university graduates earned one million yen more than the liberal arts course faculty graduates, the earning difference increased as their age went up.

The special duty professor Kazuo Nishimura of Kyoto University Economic Research Institute supposed that ｢The liberal arts course graduates had high profit was part of the theory though, the result was different. One reason is that those from science course by acquiring the technology are able to choose a wider range of occupations. ｣

It operated in June, 2008 by the private research company Monitor by the method of receiving answers from the university graduates. The reply from graduates of over 100 national public and private universities aged between 20s to 60s totaling 1632 people (988 liberal course people, 644 science course people) were analysed and the result was that the average annual salary of science course was 6.81 million yen, greatly exceeded the liberal arts course of 5.83 million yen.

If to see it according to age, at the point in time at the age of 25, the liberal arts course was 3.06 million yen and the science course was 3.66 million yen, there was a difference of 600,000 yen, at 60 years old the liberal arts course was 7.2 million yen while the science course was 8.88 million yen, the difference had extended to 1.68 million yen. When dividing the entrance difficulty into three stages according to the deviation value to see it, the difficulty in science course exceeded the liberal arts course in all stages.

It was announced after finishing the analysis of results and the completion of the thesis. According to special duty professor Nishimura , it had been said many years ago that the graduates of one university had been investigated, and the research result was that "The liberal arts course graduate lifetime income is about 50 million yen higher", now that had been put out.

It seems that the present survey is more reliable than the one done many years ago.
