Mathematical Publications: Citation Longevity, Collaboration Trends, and Authorship Statistics

Have you ever wondered how the world of mathematical research actually works? Here are some surprising facts about how mathematicians publish their work — and why traditional quality metrics often fall short.

Citation Longevity in Math Publication Statistics

Unlike other sciences, mathematical papers remain relevant for decades. The average citation lifespan in mathematics is 10 years, and for classical works it stretches even longer. Papers in algebra, for instance, can still be in demand 50 years after publication. This reveals why metrics like the “impact factor” — which measures average citation counts over short windows — are a poor fit for evaluating mathematical research.

Math Publication Statistics: Growth and Collaboration Trends

The number of mathematical publications grows by 3% every year, while the number of authors grows by 4.5%:

• On average, 2.5 authors collaborate on a single paper — though this varies considerably. In applied areas like machine learning, the average reaches 4–5 authors, while classical disciplines such as number theory or topology average around 2.
• Over the past 40 years, the share of multi-author papers has risen from 25% to 60%. Collaboration has become a defining feature of modern mathematics.

Authorship Distribution in Mathematical Publishing

The distribution of output across authors is strikingly uneven:

• 44% of mathematicians publish just one paper over their entire career, often tied to their dissertation (though calling them mathematicians at that point does feel a little generous).
• 10% of authors publish 10 or more papers. The all-time record holder, Paul Erdős, authored an astonishing 1,769 works during his career — more than most people could read in a lifetime.

Citation Distance and Professional Networks

In mathematics, citations frequently come from close colleagues or co-authors. The average “citation distance” between authors is just 3 steps. This highlights how much professional networks and collaborative projects shape the flow of ideas within the field.

What Math Publication Statistics Reveal About Metrics and Reality

High citation counts in mathematics do not always signal importance. For example, 12% of all references in mathematical papers are self-citations. The impact factor, meanwhile, routinely ignores long-term contributions and the depth of ideas — two things that matter most in this discipline.

What Does This All Mean?

Mathematical publications are more than a record of accumulated knowledge — they reflect the unique spirit of the discipline itself. Mathematics advances slowly, collectively, and with profound respect for the longevity of ideas.
