Public data
2026 budget datasets
Explore three separately published budget trees, their original sources and the reproducible download snapshot. This independent project is not a government publisher.
These are three separate governments, not one official consolidated City budget. The City and Park District use 2026 budgets, while CPS FY2026 runs July 2025 through June 2026. Transfers across governments may overlap.
Published download snapshot generated (data-build date, not the original source publication date). Immutable publication revision d95e4d265c982938b4b4a85cd61c8e1a37e6ac8c contains the complete release. Its site manifest records the earlier source/export revision cac392292e4a9a4e114ffa08a86198ec212522c8, not the publication revision; the current interactive site's export may be newer. Amounts in source JSON are integer cents, not dollars. The publication catalog lists SHA-256 checksums, original paths and byte counts per file. Download in GitHub rather than duplicating hundreds of megabytes on this site.

The original-input layer preserves public-source names that are intentionally omitted from website pages. Its publisher terms remain distinct; this site does not grant a blanket license over government records. See license and source terms. Read the budget explainers.
