Warnung vor alternden wissenschaftlichen Arbeitskräften in der EU[en][fr] 

With ageing populations, EU member states should pay special attention to human resources in science and technology (HRST) "to ensure that their hard-earned knowledge is conserved", conclude Eurostat statistics on senior HRST in Europe, published on 18 March 2008.

Eurostat refers to an annual report on science and technology in Japan, which argues that the rapid ageing of Japanese society has led to a growing proportion of the middle-aged and seniors in science professions. As the trend of fewer children and ageing population is set to continue, the Japanese expect that the number of researchers and engineers will decrease rapidly.

To remedy the situation, the country's industry, academia and research institutions recommend special treatment for older researchers so that they can continue their work and display their creativity.

As to the EU, the share of European HRST aged 45-64 fluctuated between 30% and 50% in 2006. Bulgaria, Finland, Germany and Sweden had the highest proportion of senior HRST in the EU-27, around 46%. Meanwhile, Spain and Ireland had the lowest proportion of senior HRST (some 30%) as well as relatively high number of young HRST in the 25-34 age group. 

The statistics also conclude that "senior employed HRST aged 45-64 were less mobile than younger employed HRST". Only Denmark and the UK had a relatively high mobility of senior scientists, possibly due to their flexible labour force policies that encourage mobility. 

Supporting the mobility of researchers is one of the objectives of the EU's Lisbon Strategy for growth and jobs as mobile science and technology human resources contribute to better knowledge transfer between industry, academia and research organisations, which in turn are expected to lead to increased innovation.

Since the Lisbon declaration in March 2000, EU member states have also been stressing the need to increase the number of people entering science and technology careers. In terms of human resources, it is estimated that an extra half a million researchers (or 1.2 million research-related personnel) are needed to meet the Lisbon goals of innovation and competitiveness.
