Library Stat of the Week #31: Where there is more librarian support, the share of women completing degrees compared to men is higher

In last week’s Library Stat of the Week,  we looked at the relationship between the number of librarians per student and per researcher, and rates of completion of studies and publication per researcher respectively.

This week, we dig a little deeper into the first of these two questions by using gender dis-aggregated data for completion rates from the OECD.

In effect, this allows us to understand whether greater levels of academic or research librarian support for students (calculated by the number of students each librarian serves) can be associated with a more or less favourable gender gap for women.

Graphs 1, 2 and 3 do this for students at bachelor’s, masters and doctoral levels respectively. In each graph, each dot represents a country for which data is available.

On the horizonal (X) axis, there is the number of students per librarian. Countries which are more to the left have fewer students per librarian (a proxy for better librarian support), while those on the right have more students (and so less librarian support).

On the vertical (Y) axis, there is the result of subtracting the completion rate for women from the completion rate for men. A figure above zero indicates that a greater share of men complete their studies than women, while a figure below zero suggests that more women finish than men.

Graph 1: Bachelors Degree Completion Gap


Graph 2: Masters Degree Completion Gap

Graph 3: Doctoral Degree Completion GapAcross the three graphs – and so at all levels of study – it appears that where there is greater level of support from librarians (i.e. each librarian has fewer students to support), the gender gap is more favourable to women.

In terms of the strength of the relationship, it is relatively similar across the levels, with the closest correlation seen at doctoral level (which may make sense, given the intensity of research required for this).

Outside of library support, it is noticeable that while the gender gap tends to favour women at bachelors and masters level, more men tend to complete their doctorates than women.

As part of any gender equality strategy, efforts to ensure that more women get the qualifications needed to get into the highest skilled jobs are likely to play a key role. At the doctoral level, there is clearly work to be done. It could be worth looking further at the role that stronger libraries services can play in ensuring that women get the support needed to complete their studies at this level.

Library Stat of the Week #30: Countries with more librarians per student tend to have higher completion rates

In last week’s Library Stat of the Week, we explored in more depth the relationship between numbers of students and researchers as a share of the population, and numbers of academic and research librarians available to support them.

This helped to highlight the variation that exists between countries, and in particular which ones manage to combine a strong student or research sector with adequate librarian support.

Having figures for the number of students and researchers allows us to look at potential relationships between the level of library support they receive (calculated in terms of the number of students or researchers an individual academic or research librarian serves) and outcomes.

Therefore, in this week’s Library Stat of the Week, we will be using, for the first time, OECD data on tertiary education completion rates (as a measure of whether students receive the support necessary to finish their courses), and publishing and patenting data, as used in previous editions.

Graph 1: Academic/Research Library Workers per Student and Student Completion Rates

Graph 1 looks at completion rates (from OECD data, for students at all levels) and compares these with previously calculated figures about the number of students each librarian serves on average.

It finds a small, negative correlation between the two – in other words, the more students an academic/research librarian needs to serve, the lower the likelihood of the student completing their studies.

Clearly, other factors also play out – the OECD itself notes that where courses are shorter, completion rates are higher, and of course student financing also plays a role.

Nonetheless, while of course this sort of analysis cannot show causation, it does indicate that where students have greater access to librarians, they are more likely to complete their courses.


Turning to research, our previous posts looking at the relationship between libraries and innovation were based on numbers of academic/research library workers in the population as a whole.

This, while showing that more librarians tended to mean more publications and more patents, had the weakness of neglecting indicators of the strength of the research field as a whole.

To remedy this, we can now use figures from the last two weeks which calculate the number of researchers each academic/research library worker has to serve, giving a much better idea of whether more (or less) library support for research correlates with outcomes in terms of publications and patents.

Graph 2: Academic/Research Library Workers per Researcher and Publications per Researcher

Graph 2 does this for publications, looking at whether researchers with more academic library support tend to publish more. To do this, we created a measure of number of publications per researcher by dividing figures for numbers of publications (World Bank) by those for the number of researchers (OECD).

The graph does indeed show this – when each academic/research library worker has fewer researchers to serve, the researchers tend to publish more articles each.

Graph 3: Academic/Research Library Workers per Researcher and Patents per Researcher

Graph 3 performs the same exercise for patents, using a figure for patents per researcher calculated again using World Bank and OECD data.

As with publications, this again shows a correlation, with countries where each academic or research library worker needs to serve fewer researchers each, on average, having higher rates of patenting per researcher.


As ever, correlation is not causation, although the analysis here does allow us to focus more precisely on the relationship between the strength of the academic and research library field and innovation performance per country.

While further research would be needed in order to demonstrate direct causality, these figures do allow us to say that those countries which provide stronger library support to students and researchers (as measured by numbers of students or researchers per academic and research library worker) tend to have higher student completion rates, and higher rates of publishing and patenting per researcher.

Library Stat of the Week #24: Where there are more academic librarians, there is more publishing and patenting

As highlighted in last week’s post, academic libraries are central to any country’s infrastructure for learning and innovation. Through giving learners and researchers access to existing knowledge, and support to make the most of it, they enable work to happen that leads to social and economic progress.

Last week’s post offered an initial overview of data about academic libraries and library workers in IFLA’s Library Map of the World database, suggesting that there are, on average, 1.32 academic libraries and 10.63 academic library workers per 100 000 people.

Within this, there is strong variation across countries, with, for example, there being 26.25 academic library workers per 100 000 people in the United States, but fewer than 0.1 elsewhere.

What might this mean for the ability of countries to innovate?

In this week’s Library Stat of the Week, we’ll take a first look at data on some common metrics of innovation performance – numbers of scientific publications, and numbers of patents – in order to look for potential correlations.

For this, we can cross data from the Library Map of the World (using figures for numbers of librarians and libraries per 100 000 people), and World Bank data on scientific and technical journal articles, and on patent applications by residents, also translated into figures for numbers per 100 people.

Graph 1: Academic Libraries and Publications

Graphs 1 and 2 do this in the case of publications. The link between the strength of the academic library network and the number of scientific and technical publication is relatively clear, and makes sense intuitively.

Researchers with better access to books, journals and other resources, through libraries, are better placed to write high-quality articles themselves, likely to be accepted in good quality journals.

Graph 2: Academic Library Workers and PublicationsInterestingly, the correlation is stronger in the case of academic library workers (Graph 2) than in that of academic libraries (Graph 1).

It is likely that numbers of library workers is a better indicator of the strength of the field, both given the importance of staff in helping researchers, but also potential variation from country to country in how academic libraries are organised and counted.

While, as always, correlation does not mean causality (a point we will return to below), the graph does at least seem to back up the argument that a stronger library field will tend to support a higher publications output.

The next stage is to look at patents. These are often treated as a key indicator of the innovation performance of countries, given that they can be associated with new products, services and so business.

Graph 3 Academic Libraries and Patent ApplicationsGraphs 3 and 4 therefore repeat the exercise with patent application data, comparing numbers of academic libraries and library workers per 100 000 people.

In this, in order to avoid distortion, some countries with outlying data (notably the extremely high patenting figures for China and South Korea) have been excluded in order to allow for a better look at others.

It is clear that the relationships are less clear with patents than they are with publications. This is perhaps understandable – much patenting activity comes from businesses, while publications tend to come from universities and research centres

It is already clear that correlations are weaker here – indeed, there seems to be little correlation at all between the number of academic libraries and patents at all (Graph 3).

Graph 4: Academic Library Workers and Patent ApplicationsNonetheless, on the stronger indicator of the strength of academic library fields – the number of academic library workers per 100 000 people (Graph 4) – the correlation does reappear, although is still slightly weaker than with publications.


Overall, these results do support the conclusion that countries which perform better on traditional metrics of innovativeness are also the ones that have a stronger academic library field.

As mentioned above, this is not necessarily the same as causality. In next week’s Library Stat of the Week, we will therefore try to control for some of the other potential factors which might influence this connection.
