How the UN system is financed, 2011–2024

One question, answered only with published CEB and UNGM data:

What does the way the UN system is funded allow it to do?

CORE 7.8% OF TOTAL REVENUE · 11.4% OF VOLUNTARY CONTRIBUTIONS (2024)◆ $290.6B COUNTRY EXPENDITURE WITHOUT A COMPARABLE FUNCTIONAL BREAKDOWN (CEB SERIES BEFORE 2018)◆ 7 ENTITIES RECEIVE >50% OF GOVERNMENT CONTRIBUTIONS FROM ONE GOVERNMENT◆ WFP -37% REVENUE CHANGE 2022 TO 2023◆ 69× RANGE BETWEEN HIGHEST AND LOWEST SDG, RESOURCES TAGGED BY SDG (2018–2024; 62× ON EXPENDITURE ROWS ONLY)◆ 30.6% US SHARE OF GOVERNMENT CONTRIBUTIONS (2024)◆ 230 GOVERNMENT CONTRIBUTORS AS LISTED BY THE CEB · 48 ENTITIES · $777B REVENUE 2011–2024◆

What the published data shows

7.8%
Core share of total revenue, 2024
Core contributions were 7.8% of total revenue and 11.4% of voluntary contributions. Earmarked funding rose from 49.6% of revenue in 2011 to 60.6% in 2024.

30.6%
Largest government contributor share, 2024
The United States provided 30.6% of government contributions; the second-largest government contributor provided 10.2%. In 7 entities one government provides more than half of government contributions.

Expenditure without a comparable functional breakdown (CEB series before 2018)
The CEB expenditure-by-function series starts in 2018: 43.7% of country-level expenditure 2013 to 2024 ($290.6B, all of it in 2013 to 2019) has no comparable breakdown into humanitarian, development, peace or normative functions. A series break in the published data, not a reporting failure.

About

Why this study exists.

Large institutions generate large amounts of data. Most of it is published, by obligation, by statute, by the institutions themselves. Almost none of it is read, aggregated, or presented in a form that makes the patterns visible to anyone outside the institutions that generate it.

Flows exists to close that gap. I take public data, from international institutions, governments and statistical bodies, and do the work of making it legible: cleaning, aggregating, cross-referencing and visualising until the structural patterns become readable.

I hold no policy position. I do not advocate. I do not infer intent. I publish what the data shows, cite every source, document every limitation, and leave the interpretation to those who read it.

The name: carta blanca, a blank page. What you write on it is what the evidence allows.

Principles
01Primary sources only. Every figure is traceable to an official statistical publication. No estimates, no imputations, no generated data.
02Report, don't interpret. Reports what is published. Measures it against declared methodology. Shows where published series are incomplete or not comparable. Infers no intent.
03Document the limits. Every study includes a formal methodology note listing known gaps, limitations, and what the analysis cannot claim.
04Fully reproducible. Anyone with access to the cited primary sources can replicate every number in every study. That is the test.
05Respectful tone, always. The individuals who work within these systems are not the subject of analysis. The structures are.
About this study

Why this study exists

The CEB and UNGM publish UN system financing in detail, but across many separate datasets that are rarely read together. Flows puts those public series side by side, so that funding quality, donor concentration and reporting gaps can be discussed on the same evidence.

Method in three lines. 1. Download the published CEB Financial Statistics, CEB HR Statistics and UNGM reports. 2. Compute every headline figure with one script into a single file, flows.json, that stores source, years, formula and limitation. 3. Publish only what the data supports, and show gaps as gaps. Full methodology.
