How This Data Was Compiled

Budget Figures

City agency budget figures reflect the NYC FY2027 Adopted Budget, published by the NYC Office of Management & Budget (OMB) in June 2026 and retrieved from the NYC OpenData Expense Budget dataset. These are the appropriations approved by the City Council at the start of the fiscal year (July 1, 2026 – June 30, 2027). Five bodies that sit outside the city expense budget (NYC Health + Hospitals, NYCHA, EDC, the School Construction Authority, and CUNY) instead use figures from their own most recent published budget documents.

The figures shown are total budget for each agency, they include city funds, state funds, federal funds, and intra-city funds, but not all sources are broken out individually. For very large agencies (DOE, HRA, H+H), the city-funded share may be substantially smaller than the total shown.

For off-budget or independently-financed entities (e.g., NYCHA, NYC Health + Hospitals, EDC), the figures shown represent city subsidy and operating budget as reported in the Adopted Budget overview. These organizations have separate revenue streams (rent, patient fees, grants) that are not fully captured here.

Headcount Figures

Headcount reflects budgeted full-time positions for FY2027 as reported in the Adopted Budget (the adopted position count in the OMB Expense Budget dataset). For the five bodies outside the city expense budget, and for the three library systems whose staff are not city positions, headcount comes from each entity’s own reporting.

Headcount does not include:

• Contracted workers (e.g., security guards, janitorial staff, social service providers under contract)
• Seasonal or temporary workers at agencies like Parks or Sanitation (which see large headcount spikes in summer)
• CUNY or library staff funded entirely through non-city grants

For public authorities like NYCHA (~10,900) and NYC Health + Hospitals (~42,000), headcount reflects total employees of those entities, not only those paid by city funds.

Government Body Selection

This explorer includes approximately 80 distinct operating agencies, authorities, and major elected offices. The following types of entities are excluded:

• Debt service (a large budget line, not a government body)
• Pension contributions (managed by TRS, NYCERS, BERS, Police Pension, Fire Pension, these are tracked separately)
• Miscellaneous appropriations and reserve funds
• Interagency programs (energy, fringe benefits, citywide overhead)
• Water and sewer funds (shown separately from DEP's expense budget)

Some agencies that share a headcount or budget line in the official budget are shown separately here for clarity (e.g., the five DA offices appear individually).

Sector Classifications

Government bodies are grouped into nine sectors for the treemap view. These are editorial categorizations by NYCuriosity, they do not correspond to official NYC budget categories, which use a different grouping system.

Known Limitations

• Budget figures are from the Adopted budget, not the Modified or Final budget. Actual spending in FY2027 may differ due to mid-year modifications, emergency appropriations, or savings actions.
• Multi-agency programs (e.g., the DSS umbrella covering both HRA and DHS) may lead to some double-counting in aggregate sector totals if you add individual lines.
• The libraries (NYPL, BPL, QPL) receive city subsidies but are legally independent nonprofits; total organization revenue is larger than the city contribution shown.
• NYC Health + Hospitals runs on a revolving fund with significant Medicaid and commercial insurance revenue; the $10.3B figure here reflects total operating revenue, not city subsidy alone.
• Data was compiled by hand from public budget documents; small rounding differences from official published totals are possible.
