What Society for Industrial and Applied Mathematics does
Mission
Incorporated in 1952 as a non-profit organization, siam has worked toward the following goals for more than 70 years:-to advance the application of mathematics and computational science to engineering, industry, science, and society;-to promote research that will lead to effective new mathematical and computational methods and techniques for science, engineering, industry, and society;-to provide media for the exchange of information and ideas among mathematicians, engineers, and scientists.
As stated on its FY2024 Form 990.
Programs
Siam's publications are a means of meeting one of the primary objectives for organizing the society: to provide media for the exchange of information and ideas between mathematicians and other scientists. Siam's journal program produces 18 quality, peer-reviewed journals that are respected and highly cited throughout the applied mathematics and computational science community. Siam publishes approximately 20 high-quality books a year by authors who are experts in their field, making relevant research results accessible to industry and science while also promoting the interaction between mathematics and other disciplines such as engineering, science, and computing. Siam news, published 10 times per year, is the news journal reporting on issues and developments affecting the applied and computational mathematics community. Siam also publishes undergraduate research online (siuro), an open-access publication for undergraduates.
$5,354,086 spentof which $169,408 as grants$7,649,009 earned by the program53% of program spendingSiam's conference program provides members and attendees with a broad view of the state-of-the-art in applied mathematics and computational science. Through invited presentations, prize lectures, minisymposia, mini-tutorials, contributed papers, and posters, members are able to join their peers and leading experts in the field to exchange ideas and to expand their personal and professional networks. Siam holds ten to twelve conferences each year, each focused on timely topics in applied mathematics and computational science. The work at these conferences helps demonstrate that many societal problems can be solved through various methods of applied mathematics and computational science. Siam offers travel support for students through siam student travel awards to attend the conferences.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $63M to $51M (−19%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2017 2% · 2018 2% · 2019 10% · 2020 0% · 2021 9% · 2022 3% · 2023 3% · 2024 4%. Grants only. Government contracts and fees sit inside program revenue.
11% of SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS’s revenue is contributions — about as donation-reliant as the typical peer (52% for the typical peer).
Surplus & reserves

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 4 funders, grant income fell $70k → $27k.
5 of 14 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 32% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS has a broad base — no single funder exceeds 17% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
89% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS.
Largest funder’s share by year: 2017 88% · 2018 63% · 2019 75% · 2020 99% · 2021 52% · 2022 99% · 2023 57% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
17% of SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS's funders are still giving 3 years after their first grant; 43% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
SOCIETY FOR INDUSTRIAL AND APPLIED MATHEMATICS draws 100% of its grant income from funders outside Pennsylvania, across 7 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $125k arriving through sponsors registered in 4 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
