Women in Science: Measuring Participation in Europe Across Disciplines, Generations and Over Time
This study utilizes structured Big Data from 1990 to 2023 to quantify the inflow of women scientists across 14 STEMM disciplines in Europe, revealing that while women have significantly driven scientific growth in several fields, their participation remains marginal in highly mathematized disciplines like mathematics, computer science, physics, and engineering.

Imagine the world of science as a massive, bustling city called STEMM City. For decades, this city was built almost entirely by men. But over the last 30 years, a huge wave of women has started moving in, changing the city's demographics.
This paper is like a giant, high-tech census taken by two researchers, Marek and Lukasz, who used a "super-microscope" (a massive database called Scopus) to look at 1.7 million scientists across Europe and a few other countries. They didn't just count heads; they asked three big questions:
- Are women moving into all neighborhoods of the city at the same speed?
- Is the new wave of young scientists different from the older generation?
- Are there some neighborhoods where women are still stuck at the gate?
Here is the story of what they found, told in simple terms.
1. The City is Split in Two: The "Green Zones" vs. The "Fortresses"
The researchers discovered that STEMM City isn't one uniform block. It's actually two very different worlds living side-by-side.
The "Green Zones" (The Welcome Neighborhoods):
In neighborhoods like Medicine, Biology, Pharmacology, and Immunology, the city has become very balanced. In fact, in some of these areas, more than half of the new residents are women. If you walked down the street in these neighborhoods today, you'd see a mix that is almost 50/50, or even more women than men among the young people. It's like a park where the benches are finally shared equally.The "Fortresses" (The Math-Heavy Neighborhoods):
Then there are four specific neighborhoods: Mathematics, Computer Science, Physics, and Engineering. These are the "Fortresses." Even though the city is changing, these four areas are still very hard to get into for women.- In 2023, only about 16% to 21% of the people working in these fields were women.
- It's like a club where the door is still mostly closed to women. Even though the number of women has tripled since 1990, they are still a tiny minority compared to the men.
The Takeaway: You can't just say "Women are doing great in science." In some parts of science, they are the majority. In others, they are still fighting to get a seat at the table.
2. The "Time Machine" Effect: Looking at Generations
The researchers used a clever trick to see the past and future. They looked at scientists based on how long they have been publishing papers.
- The "Old Guard" (40+ years of experience): These are the scientists who started their careers when the "Fortresses" were almost entirely men. If you look at the Engineering neighborhood today, the older women there are the pioneers who had to climb a very steep mountain alone.
- The "New Wave" (5–10 years of experience): These are the young scientists just starting out.
The Magic of the Data:
The data acts like a time machine. It shows that in the "Green Zones" (like Medicine), the young women are already the majority. But in the "Fortresses" (like Engineering), even the young women are still a small group.
- Analogy: Imagine a high school. In the Art class, half the students are girls. In the Advanced Robotics class, there are only two girls, even though the school is trying to change. The researchers found that while the whole city is getting more diverse, the Robotics class is changing very slowly.
3. The Three Big Hurdles (Methodology)
The authors had to solve three tricky puzzles to make this study work, which they explain in the paper:
- The Name Game (Gender): The database didn't have a "Gender" checkbox. The researchers had to guess if a scientist was a man or a woman based on their first name (like "Sarah" vs. "John"). They used a smart computer tool to do this. It's not perfect (some names are tricky), but it's the best way to look at millions of people at once.
- The Age Guess (Academic Age): The database didn't have birth dates. So, they guessed a scientist's "career age" by looking at the date of their very first published paper. It's like guessing someone's age by looking at their first driver's license. It's an estimate, but it works well enough to see trends.
- The Labeling (Discipline): A scientist might write about many things. The researchers had to decide which "neighborhood" (discipline) they belonged to. They looked at all the papers a scientist cited to figure out their main focus.
Why Does This Matter?
For a long time, people thought "Science" was one big thing. This paper says, "No, it's many different things."
- The Good News: We don't need to panic about women leaving science. In many fields, they are arriving in huge numbers. The "pipeline" is full.
- The Bad News: We can't treat all science the same. If a government says, "Let's get more women in Engineering," they can't just copy the rules that worked for Medicine. The "Fortresses" need special, different keys to open the door.
In a nutshell:
The world of science is undergoing a massive renovation. In the Medical and Biological wings, the renovation is nearly done, and women are running the show. But in the Math and Engineering wings, the construction is slow, and the women's section is still very small. To fix the whole building, we need to stop looking at the whole house and start fixing the specific rooms that are still broken.
