The EMS has as its members around 60 national mathematical societies in Europe, 40 mathematical research centres and departments, and 3000 individuals.
- Institute of Mathematics and its Applications (IMA) The Institute of Mathematics and its Applications (IMA) is the UK's learned and professional society for mathematics and its applications. The IMA exists to support the advancement of mathematical knowledge and its applications and to promote and enhance mathematical culture in the United Kingdom and elsewhere, for the public good.
- International Centre for the Mathematical Sciences ICMS supports research in the mathematical sciences. Its core activity is the development and organisation of international workshops and conferences in all areas of mathematics and these attract leading mathematical scientists from the UK and overseas.
- Isaac Newton Institute for Mathematical Sciences The Isaac Newton Institute for Mathematical Sciences is a national and international visitor research institute. It runs research programmes on selected themes in mathematics and the mathematical sciences with applications over a wide range of science and technology. It attracts leading mathematical scientists from the UK and overseas to interact in research over an extended period.
- London Mathematical Society The London Mathematical Society is the major UK learned society for mathematics. The Society's activities include publishing journals and books, providing grants to support mathematics and organising scientific meetings and lectures.
- Royal Statistical Society The Royal Statistical Society (RSS) is one of the world's most distinguished and renowned statistical societies. It is a learned society for statistics, a professional body for statisticians and a charity which promotes statistics, data and evidence for the public good. It was founded in 1834 as the Statistical Society of London and became the Royal Statistical Society by Royal Charter in 1887. Today the Society has more than 6000 members around the world, of whom some 1250 are professionally qualified as Chartered Statistician. The RSS is active in a wide range of areas both directly and indirectly relevant to the study and application of statistics.
- Society for Industrial and Applied Mathematics SIAM exists to ensure the strongest interactions between mathematics and other scientific and technological communities through membership activities, publication of journals and books, and conferences.
- The Mathematical Association The Mathematical Association exists to support and enhance Mathematics and the teaching and learning of Mathematics and its applications, and to provide opportunities for collaboration and communication between teachers and students of mathematics.
- The Royal Society The Royal Society is a self-governing Fellowship of many of the world’s most distinguished scientists drawn from all areas of science, engineering, and medicine.
