Growth of academic research

This document provides some historical data on the growth of the academic research sector. Most of the data included in this document refers to the STM market (the fields of Science, Technology, Medicine) unless otherwise noted. All data and figures have sources.

Journals and articles.

There were about 28,100 active scholarly peer-reviewed English-language journals in late 2014 (plus a further 6450 non-English-language journals), collectively publishing about 2.5 million articles a year. The number of articles published each year and the number of journals have both grown steadily for over two centuries, by about 3% and 3.5% per year respectively, though there are some indications that growth has accelerated in recent year (from STM Association report)

Authoring practices

Scientific articles have increasingly become more and more collaborative. (Vesterman 2002)

Publishers and market size

The annual revenues generated from English-language STM journal publishing are estimated at about $10 billion in 2013, (up from $8 billion in 2008, representing a CAGR of about 4.5%), within a broader STM information publishing market worth some $25.2 billion. About 55% of global STM revenues (including non-journal STM products) come from the USA, 28% from Europe/Middle East, 14% from Asia/Pacific and 4% from the rest of the world.
