Age diversity in science

Department: Editor's Page
Keywords: editorial, opinion, diversity

In C&EN we regularly run feature stories that exemplify diversity in the chemical sciences and how workplaces are adapting to create a more welcoming and inclusive environment for underrepresented and marginalized groups.

For example, last year we explored the experience of chemists in the lesbian, gay, bisexual, and transgender community who face barriers to promotion or adversity on the job, and how they navigate these challenges.

We also reported on a gender survey carried out by the Open Chemistry Collaborative in Diversity Equity (OXIDE) that tracks the overall percentage of women faculty at top chemistry departments. Look for the companion survey on underrepresented minorities in chemistry departments later this year.

Each year we also report goings-on from the annual National Organization for the Professional Advancement of Black Chemists & Chemical Engineers meeting and how NOBCChE is working to grow and nurture the next generation of black chemists and engineers.

So we often write about diversity and inclusion for chemists from the LGBT community, for women chemists, and for chemists from other nationalities and races, but we don’t tend to write about age diversity in the chemical sciences, or any science, all that frequently.

I recently came across a paper that broached this subject in the context of the U.S. science and engineering workforce. In many ways, the scientific community is becoming more diverse, but this does not seem to be the case when it comes to age. According to the authors of the study, the scientific workforce in the U.S. is aging rapidly.

The authors observed an increase in the mean age of scientists, which went from 45.1 in 1993 to 48.6 in 2010. The age distribution of the scientific workforce in the U.S. between 1993 and 2010 shows a significant decline in the share of scientists aged 35–53, with a significant increase in the share older than 53. Interestingly, although the workforce as a whole is also aging, it has a substantial mass at younger ages compared with the scientific workforce. It is also aging at a slower pace: from 42.2 to 45.4 from 1993 to 2010.

Much of this trend is driven by the aging of the large baby boom cohort that is currently employed. The authors call this a “demographic momentum” that is likely to continue for the next two decades as the cohorts of baby boomers age into their 60s and early 70s. A small percentage (8%) of the increase in scientists’ mean age can be attributed to a decline in retirement at universities since 1994, the year when mandatory retirement was eliminated. Other reasons for this age distribution of the scientific workforce include declining mortality and fertility rates.

Worryingly, the current trend predicts further aging of the scientific workforce in coming years. Younger scientists may be crowded out. Besides the human cost, which is not insignificant, what will be the impact of this trend in productivity and innovation? If we assume that both decline with age—and there are plenty of studies presenting mixed views on the matter—are we saying that productivity and ability to innovate in the U.S. may suffer in the short and medium term? It’s a grim prospect. We must work to ensure the voices of the younger generations of scientists are heard.

Diversity comes in many forms—gender, religion, sexual orientation, socioeconomic background, and of course age—and is an ambitious goal that requires a conscious and concerted effort by all in the community. Successfully bringing together people of various backgrounds with various perspectives and experiences to help solve global challenges should become the hallmark of our generation.

Interesting editorial but chemists are working longer because of the uncertainty of retirement from industry. It may peprolonged in Education just because summer is open for faculty. Industry is a mess as companies continue to eliminate pension plans. Those older chemists who change jobs often run into that they have insufficient funds in their pension plans because the value is longevity in the same company. Layoffs destroy many retirement plans of older chemists. Also the business segment who rum chemical companies these days would like to see all the older chemists disappear for financial reasons. Maybe why there are so many layoffs. Hard to prove. But working in industry for 36 years have had made many observations. Towards the the last 10-15 years of my chemical career these were many layoffs almost every year as business changes/focus continually changes with mergers and products. Older chemists were always at risk of layoff when this happens. They have the experience and move on to another company, but their retirement benefits take a hit and they need to work longer.

The editorial advocating for age discrimination was provocative. Why should older people be taking up so many positions when, in the words of the Editor-in-chief, we assume that both productivity and innovation decline with age? Let's put aside any pesky data to the contrary. Let's also put aside the fact that many older chemists are financially unable to retire because of excessive industry layoffs and the consequent unemployment or underemployment. Instead, we need to address the worrisome trend that the mean age of scientists in 2010 was 48.6 years. I suggest that the Creative Department at c&en create one of those wonderful emoji--perhaps a 49-year-old chemist on an iceberg?
