Methodology

Transparent sourcing, calculation, and presentation of federal budget data

Data Sources

Primary Budget Data: USAspending.gov

All federal budget and spending data is sourced from USAspending.gov, the official open data source of federal spending information managed by the U.S. Department of the Treasury.

What we use:

  • Agency budget authority and obligations
  • Object class spending (personnel, contracts, grants, etc.)
  • Function and subfunction categorization
  • Award-level transaction data for specific programs
  • Historical spending trends (fiscal year 2017-present)

USAspending.gov aggregates data from the Financial Management System (FMS), Federal Procurement Data System (FPDS), and other authoritative federal sources mandated by the Digital Accountability and Transparency Act (DATA Act) of 2014.

Comparison Unit Sources

To provide meaningful context, we translate budget figures into relatable units using data from authoritative statistical sources:

Bureau of Labor Statistics (BLS)

Median household income, average wages by occupation, consumer price indices

bls.gov

Kaiser Family Foundation (KFF)

Average health insurance premiums, out-of-pocket healthcare costs

kff.org

U.S. Department of Health and Human Services (HHS)

Medicare/Medicaid per-beneficiary costs, public health program expenditures

hhs.gov

U.S. Census Bureau

Population counts, household statistics, economic indicators

census.gov

National Center for Education Statistics (NCES)

Average cost of public education, teacher salaries, school funding

nces.ed.gov

Example Calculation

How We Calculate: Defense Spending in Teacher Years

Step 1: Get the budget figure

Department of Defense FY 2025 Budget Authority: $841,400,000,000

Source: USAspending.gov API, Function 051 (National Defense)

Step 2: Get the comparison unit

Average public school teacher salary: $66,397

Source: National Center for Education Statistics, 2023-24 school year

Step 3: Calculate the comparison

$841,400,000,000 ÷ $66,397 = 12,673,426 teacher-years

Step 4: Present with context

The Department of Defense budget of $841.4 billion could fund 12.7 million teacher salaries for one year—nearly 4x the total number of public school teachers in the U.S.

Note: This comparison illustrates scale, not policy recommendation. We do not suggest reallocating defense spending to education; rather, we use familiar units to make large numbers comprehensible.

Update Frequency

Budget Data

Updated daily via automated sync with USAspending.gov API. New fiscal year data becomes available in October when appropriations are enacted.

Comparison Units

Updated quarterly when source agencies publish new statistics. Most metrics reflect the most recent 12-month period available.

Historical Data

USAspending.gov provides reliable data from FY 2017 onward. Pre-2017 data may be incomplete due to DATA Act implementation timeline.

Caveats and Limitations

1. Budget Authority vs. Outlays

We primarily display budget authority (legal permission to spend), not outlays (actual cash disbursed). Multi-year programs may show high authority in one year but spend over several years.

2. Mandatory vs. Discretionary Spending

Mandatory spending (Social Security, Medicare, interest on debt) operates under permanent law and is not annually appropriated. Discretionary spending requires annual congressional appropriation. This dashboard shows both but does not imply equal flexibility in reallocation.

3. Inflation Adjustment

Unless explicitly noted, dollar figures are in nominal terms (not adjusted for inflation). Historical comparisons should account for CPI changes.

4. Classification Changes

Federal agencies occasionally reorganize, and budget functions/subfunctions may be reclassified. We use the most current classification scheme, which may affect year-over-year comparisons.

5. Comparison Limitations

Comparisons are illustrative and do not represent policy endorsements. A comparison showing “X could fund Y” does not imply substitutability or equivalence of value. Budget decisions involve complex trade-offs not captured by simple arithmetic.

6. Data Quality

While USAspending.gov is the most authoritative source, occasional reporting errors or delays may occur. We cross-reference with OMB and CBO publications where possible. Discrepancies are noted in context.

7. Off-Budget Items

Some spending (e.g., Social Security, USPS operations) is technically “off-budget” but is included in unified budget reporting. We follow OMB conventions for consistency.

Why These Comparisons Matter

Making Billions Comprehensible

The federal budget operates in billions and trillions—numbers far beyond everyday experience. When the Department of Defense spends $841 billion, that figure is technically accurate but cognitively meaningless to most people. By translating spending into relatable units (teacher salaries, healthcare costs, median incomes), we bridge the gap between abstract accounting and lived reality.

Informed Democratic Participation

Budget decisions reflect collective priorities and values. Citizens cannot meaningfully engage in democratic discourse about spending without understanding what those dollars represent in human terms. These comparisons lower the barrier to informed participation in debates about taxation, spending, and national priorities.

Avoiding False Equivalencies

We are careful not to suggest that comparing defense spending to teacher salaries means we should “defund the military to hire teachers.” Budget trade-offs involve:

  • Constitutional obligations (e.g., national defense)
  • Legal mandates (e.g., Social Security benefits)
  • Economic effects (e.g., multiplier effects, opportunity costs)
  • Long-term consequences (e.g., infrastructure decay, skills gaps)
  • Political feasibility and coalition-building

Our goal is comprehension, not prescription. We provide the numbers; you provide the values.

Transparency and Accountability

By making budget data accessible and interpretable, we support transparency efforts mandated by laws like the DATA Act. When spending is legible to the public, oversight becomes more effective. Journalists, researchers, and advocates can use this tool to ask sharper questions and hold institutions accountable.

Nonpartisan Design Principle

This dashboard is intentionally neutral. We do not editorialize on whether spending is “too high” or “too low,” nor do we advocate for specific policy changes. Our role is to present data clearly and allow users to draw their own conclusions. Comparisons are selected for familiarity and relevance, not to advance a particular ideology.
