The Supply of Science Ph.D.'s

One of the odd patterns in recent years is that there is virtually universal agreement that the future of the U.S. economy is closely tied up with technological leadership. But at the same time, those who get a Ph.D. in one of the hard sciences are finding a very unwelcoming job market. Nature takes an international perspective  on this issue in "Education: The PhD factory: The world is producing more PhDs than ever before. Is it time to stop?"

Setting the stage. "The number of science doctorates earned each year grew by nearly 40% between 1998 and 2008, to some 34,000, in countries that are members of the Organisation for Economic Co-operation and Development (OECD). The growth shows no sign of slowing: most countries are building up their higher-education systems because they see educated workers as a key to economic growth ... . But in much of the world, science PhD graduates may never get a chance to take full advantage of their qualifications."

In the United States: "To Paula Stephan, an economist at Georgia State University in Atlanta who studies PhD trends, it is “scandalous” that US politicians continue to speak of a PhD shortage. The United States is second only to China in awarding science doctorates — it produced an estimated 19,733 in the life sciences and physical sciences in 2009 — and production is going up. But Stephan says that no one should applaud this trend, “unless Congress wants to put money into creating jobs for these people rather than just creating supply”. The proportion of people with science PhDs who get tenured academic positions in the sciences has been dropping steadily and industry has not fully absorbed the slack. The problem is most acute in the life sciences, in which the pace of PhD growth is biggest, yet pharmaceutical and biotechnology industries have been drastically downsizing in recent years."

In Japan: "Of all the countries in which to graduate with a science PhD, Japan is arguably one of the worst. In the 1990s, the government set a policy to triple the number of postdocs to 10,000, and stepped up PhD recruitment to meet that goal. The policy was meant to bring Japan’s science capacity up to match that of the West — but is now much criticized because, although it quickly succeeded, it gave little thought to where all those postdocs were going to end up. Academia doesn’t want them: the number of 18-year-olds entering higher education has been dropping, so universities don’t need the staff. Neither does Japanese industry, which has traditionally preferred young, fresh bachelor’s graduates who can be trained on the job. The science and education ministry couldn’t even sell them off when, in 2009, it started offering companies around ¥4 million (US$47,000) each to take on some of the country’s 18,000 unemployed postdoctoral students ..."

In China: "The number of PhD holders in China is going through the roof, with some 50,000 people graduating with doctorates across all disciplines in 2009 — and by some counts it now surpasses all other countries. The main problemis the low quality of many graduates."

In Germany:  "Germany is Europe’s biggest producer of doctoral graduates, turning out some 7,000 science PhDs in 2005. After a major redesign of its doctoral education programmes over the past 20 years, the country is also well on its way to solving the oversupply problem. Traditionally, supervisors recruited PhD
students informally and trained them to follow in their academic footsteps, with little oversight from the university or research institution. But as in the rest of Europe, the number of academic positions available to graduates in Germany has remained stable or fallen. So these days, a PhD in Germany is often marketed
as advanced training not only for academia— a career path pursued by the best of the best — but also for the wider workforce.Universities now play a more formal role in student recruitment and development, and many students follow structured courses outside the lab, including classes in presenting, report writing and other transferable skills. Just under 6% of PhD graduates in science eventually go into full-time academic positions, and most will find research jobs in industry..."

In India: "In 2004, India produced around 5,900 science, technology and engineering PhDs, a figure
that has now grown to some 8,900 a year. This is still a fraction of the number from China and the United States, and the country wants many more, to match the explosive growth of its economy and population. ... But there is little incentive to continue into a lengthy PhD programme, and only around 1% of undergraduates currently do so. Most are intent on securing jobs in industry, which require only an undergraduate
degree and are much more lucrative than the public-sector academic and research jobs that need postgraduate education."
