For years women have been underrepresented in STEM (science, technology, engineering and mathematics) university courses and occupations.  Using recent UCAS data from HESA and findings from WISE campaigns, we wanted to take a closer look at some women in STEM statistics. 

We have highlighted the imbalances that occur across STEM subjects at undergraduate level. We have also addressed the gender splits that prevail across the UK workforce within STEM related professions. This article has been updated to include an insight into how the pandemic is affecting female STEM students, a subject that is explored in greater depth in our Whitepaper.

At STEM Women we specialise in addressing the gender imbalance in STEM fields by hosting face-to-face and virtual networking events and careers fairs for STEM employers and female students studying a course in these subjects. 

Women in STEM Statistics – General Outlook for Female Students

According the recent UCAS data provided by HESA, 35% of STEM students in higher education in the UK are women.

Women in STEM Statistics

Physical sciences

Female – 22,400 – 39%
Male – 34,800 – 61%
Total - 57,240

Between 2017 and 2018, 39% of students studying physical sciences were female.

Mathematic sciences

Female - 14,100 – 37%
Male - 24,335 – 63%
Total - 38,465

In the same period, the percentage of female students studying mathematical sciences was just 37%.

Computer sciences

Female – 4,525 – 19%
Male – 19,550 – 81%
Total - 24,090

When we looked at the UCAS data for students studying computer sciences related degrees, only 19% were female, with a staggering 81% of students being male.

Engineering and technology

Female – 23,650 – 19%
Male – 102,970 – 81%
Total - 126,660

Similarly, the percentage of female students studying engineering and technology degrees made up a mere 19% of the total students between 2017 and 2018.

Women in STEM Statistics – General Outlook for Female Graduates

Since 2015, the number of women in STEM (women graduating in core STEM subjects) has grown from 22,020 to 24,705 in 2019. On the surface this would appear to show a linear increase, however, due to the more rapid growth in the number of men graduating in these subject areas, the percentage of women in STEM has fluctuated from 25%, down to 24%, and finally up to 26% where it has stalled in 2019.

Core STEM subjects – Female Graduates 

2015 – 22,020 – 25%
2016 – 22,340 – 24%
2017 – 22,950 – 25%
2018 – 24,000 – 26%
2019 – 24,705 – 26%

The UCAS data shows that year-on-year, core STEM subjects have seen only a small increase of around 1,000 female students. This shows that efforts to encourage women to enter into science, technology, engineering and mathematics fields has been somewhat successful.

Subject breakdown – Female Graduates

women in stem statistics

Physical science

2015/16 – 7,505 – 40%
2016/17 – 8,015 – 41%
2017/18 – 8,435 – 42%
2018/19 – 8,325 – 43%

From 2015 to 2018, the number of women graduating in physical science-related degrees has increased by 2%, which equates to approximately 930 more students. This is equivalent to an increase of roughly 500 graduates year-on-year. However, in 2019 the percentage still increased, but the number of women actually dropped by 110. This is due to a drop in the number of males who graduated.

Mathematical science

2015/16 – 3,620 – 39%
2016/17 – 3,765 – 39%
2017/18 – 3,690 – 39%
2018/19 – 3,660 – 38%

In mathematical sciences the number of women grew from 3,620 in 2015/2016 to 3,765 in 2016/17, however, the percentage overall remained static at 39% for both years.

In 2017/18, the number of female mathematical sciences graduates dipped slightly from 3,765 to 3,690, and again to 3,660 in 2019 – the only core STEM subject area to see a percentage decrease.

Engineering and technology

2015/16 – 4,480 – 15%
2016/17 – 4,700 – 15%
2017/18 – 5,050 – 15%
2018/19 – 5,375 – 16%

Disappointingly, the percentage of female engineering and technology graduates has remained constantly low at 15% from 2015 to 2018. However, the exact number of female students has in fact increased by roughly 570 over the period. In 2018/19 it has continued to increase which has led to a 1% increase in the percentage.

Computer science

2015/16 – 2,925 – 16%
2016/17 – 3,020 – 15%
2017/18 – 3,220 – 15%
2018/19 – 3,490 – 16%

Computer science-related degrees also see a relatively low percentage of female graduates. From 2015 to 2018, the percentage has gone from 16% to 15%. In 2018/19, the percentage has again increased back up to 16%.

The overall number of computer science graduates who are female has actually seen an increase year-on-year, but this has only maintained the same percentage overall due to more men opting to study the subject.

Women in STEM Statistics – General Outlook for Female STEM Workforce

Following our findings from UCAS data provided by HESA, we took a look at some of the Women in STEM statistics from the 2018 and 2019 workforce WISE campaigns. The organisation uses the Office for National Statistics Labour Force Survey data for generating statistics on women in the UK STEM workforce.  

Overall, WISE found that the STEM sector is continuing to grow at a rapid rate. From 2017, core STEM employment had increased by 6.3%, which equates to more than 6 times that of the total rise in the UK’s overall employment rate. In 2019, the government data showed that there are now one million women working in core STEM occupations!

2016 – 802,848 – 21%
2017 – 864,278 – 23%
2018 – 908,318 – 22%
2019 - 1,019,400 - 24%

women in stem statistics

Since 2016, the number of women working in STEM fields has increased by 216,552, which has taken the total number over the 1 million mark for the first time ever! This means women now make up 24% of the STEM workforce in the UK.

Using the data trends from the last ten years, 2009-2019, WISE have estimated that by 2030, they expect to reach over 29% of women in the STEM workforce.

Engineering professionals

2016 – 36,734 – 8%
2017 – 48,449 – 11%
2018 – 49,250 – 10%
2019 – 50,475 – 10%

women in stem statistics

In the last decade, the number of women working in engineering roles has almost doubled from 25,000 to just over 50,000. This is positive data; however, the overall percentage split is still very low and has remained static for the past two years even though the numbers have increased.

Science professionals

2016 – 64,563 – 41%
2017 – 57,372 – 42%
2018 – 58,725 – 42%
2019 – 62,675 – 46%

women in stem statistics

Women in STEM statistics for science professionals continue to show positive results for a growing gender diversity in these roles. Women now make up 46% of the total science professional workforce.

Science and Engineering technicians

2016 – 75,129 – 27%
2017 – 97,064 – 27%
2018 –87,150 – 26%
2019 – 83,525 – 25%

women in stem statistics

Between 2017 and 2018, roughly the equivalent numbers of men and women left the science and engineering technician workforce. This explains why the percentage of female workers has remained constant at 27%, but fewer women were actually employed in these roles.

In the last year, the numbers of female science and engineering technicians have dropped.

IT Professionals

2016 – 183,149 – 18%
2017 – 172,411 – 17%
2018 – 181,575 – 17%
2019 – 180,600 – 16%

women in stem statistics

Although the medium-term trend shows female numbers increasing in IT professional roles in 2017, the numbers of men working in these roles are increasing at a faster rate, jumping by 60,000 in the past year. This means the female proportion of the IT professional workforce was still only at 16% in 2019.

IT Technicians

2016 – 43,087 – 19%
2017 – 46,523 – 19%
2018 – 53,600 – 21%
2019 – 53,400 – 21%

women in stem statistics

When looking at the number of women working as IT Technicians, the figures have increased from 2016 – 2019. However, because the number of men working as IT Technicians has increased at a rapid rate, the overall percentage of women working as IT Technicians remained static between 2016 and 2017, increased slightly in 2018, but has remained static again.

Women in STEM statistics - Conclusion

From our Women in STEM statistics, it is clear that there is still more to be done to reduce the gender gap in STEM fields.

Overall, the percentage of female graduates with core STEM degrees is steadily growing, however, the split is still just 26%. This figure is also translated in the female STEM workforce, with women making up 24%. This shows that some work needs to be done to encourage women to both study these subjects, and transition into the workforce.

Specifically, computer science and engineering and technology fields show the largest gender imbalances, from current students, to graduates and the workforce figures.

Physical science-related degrees have seen a year on year increase in the number of female graduates, showing that efforts to encourage women to study chemistry and physics-based subjects have been successful.

STEM Women recently published a fascinating Whitepaper that covers themes surrounding gender diversity in STEM industries, the gender pay gap, the impact COVID-19 has had on female STEM students, the importance of mentoring schemes, and much more. We surveyed female STEM students across 2019 and 2020 with the aim of understanding the reasons why young women choose certain career paths and the hurdles they may come up against during their job search

One of the key findings was that 60% of female STEM students have had their future career prospects affected by the COVID-19 pandemic.

Has the pandemic affected your future career prospects? 

women in stem statistics

The report also found that there was a growing feeling of uncertainly and lack of confidence in the jobs market because of the pandemic, with a proportion of female STEM students saying that they are now looking for any job rather than one within their preferred industry.

In the future, we may see larger fluctuations in the workforce data due to the COVID-19 pandemic, as it has a knock-on effect on volunteering, internship, and job opportunities. You can download the full Whitepaper below for free. 

At STEM Women, we’re on a mission to address this gender imbalance. We use UCAS data and workforce data to target specific courses and locations to attract the best female STEM students looking to enter into related fields and invite them to our face-to-face and virtual networking and graduate careers events. Our events provide employers with the opportunity to introduce their graduate opportunities, speak on a panel, list their job roles online and reach out to the attendees immediately after an event. From sponsorship and stands at careers events, to job boards and recruitment consultants that specialise in sourcing the very best talent, get in touch with us today for more information.
