The UN Transparency Portal makes financial data from across the UN System accessible through interactive visualizations. Explore who contributes, which organizations receive funding, where resources are deployed, and which Sustainable Development Goals they support.
- UN System
- Contributors — Treemaps and trends showing government and donor contributions by financing instrument
- Entities — Spending breakdowns for 48+ UN organizations
- Countries — Interactive world map with geographic spending data
- SDGs — Grid visualization of spending by Sustainable Development Goal
- UN Secretariat
- Regular-budget contributors — Member State assessments and paid-in-full status
- Switch between audited-statement expenses and PPB + PKO budget-document expenditure
| Source | Coverage | Description |
|---|---|---|
| CEB Financial Statistics | 2011–2024 | Audited financial data from 48+ UN System organizations |
| UN Secretariat Spending | 2019–2023 | Granular breakdown into 150+ departments and missions |
| Programme Budget Data | PPB expenditure 2019–2025; PKO cycles 2022/23–2024/25 | PPB hierarchy plus separately assessed mission budgets |
| Committee on Contributions | Regular-budget assessments and honour rolls, 2019–2026 | Member State assessments and paid-in-full status |
| Schedule of Individual Trust Funds | 2017–2024 | Audited fund statements and contributor schedules |
| UNINFO | 2022–2024 | Cooperation Framework data for 127 countries |
The two Secretariat treemap sources are deliberately selectable rather than merged. Both source views follow the budget hierarchy and contain separate Programme Budget and Peacekeeping blocks. Their treemap areas share one USD scale, while remaining separate because the datasets use different scopes and accounting bases and peacekeeping follows a July–June fiscal cycle. Funding-source shades remain orthogonal to that hierarchy: support-account expenditure is shown as other assessed funding in the responsible programme-budget section, not as a mission.
