Datasets That Can Change A Score

This page names the data sources before the charts arrive. A source belongs here only if it can test a ledger claim, set a denominator, or expose a missing record.

Access Read

Many public sources are usable now. Some need free keys, bulk-file handling, license review, or paid market data before the site can make long-run claims without survivorship errors.

Depends on source series; ALFRED keeps vintages.
Query targets
FEDFUNDS; T10Y2Y; BAA10Y; SP500; ALFRED vintages
Ledger use
Inflation and recession context; Credit stress; Policy-rate shocks; Historical revision checks
Caveat
Use ALFRED when the claim depends on what officials knew at the time. Free price-index rows are not total-return market history.

Population, ACS, poverty, migration, education, housing, income, and local geography.

Cadence
Annual ACS, decennial census, and program-specific releases.
Query targets

Cadence
Daily, monthly, quarterly, or annual by endpoint.

Cadence
Frequent updates from agency award reporting.
Query targets
Fiscal-year obligations; Agency awards; Recipient records; Spending category

Cadence
Recurring updates tied to CBO reports and budget baselines.
Query targets

Cadence
Daily market days.
Query targets

Cadence
Frequent updates.
Query targets

Cadence
Dataset releases after election cycles.
Query targets

Cadence
Updated with congressional voting records.
Query targets

Cadence
Dataset dependent.

Cadence
Continuous updates from court and RECAP sources.
Query targets
Opinions; Dockets; RECAP filings; Citation graph

Query targets
State campaign contributions; State campaign expenditures; Original columns; Normalized search fields
Ledger use

Caveat
Treat TAP as a normalization and discovery layer. Keep original publisher, date range, original columns, and TAP processing notes before scoring.

Cadence
Survey dependent.
Query targets
Political typology; Institutional trust; News consumption; Partisan attitudes
Ledger use

Cadence
Dataset dependent.
Query targets
Threat event; Actor; Target; Location; Event type; Source
Ledger use

Cadence
Updated as litigation develops.
Query targets
Order; Case; Issue; Court; Status; Outcome
Ledger use
Executive-order litigation triage; Legal posture comparison; Source discovery
Caveat
Use as a tracker and chronology aid. Primary dockets and opinions remain the scoring record.

Open corpora

Open datasets, text corpora, metadata, and processing tools across many providers.

Cadence
Dataset specific.
Query targets
Public text corpora; Dataset cards; License fields; Revision hashes

Do not make all-history market claims from free symbol downloads alone.

Build Rules

  1. Store source URL, retrieval date, table or series ID, units, geography, denominator, and revision policy.
  2. Separate primary measurements from press volume, expert ratings, and model output.
  3. Keep raw files or immutable snapshots for every chart that supports a score change.
  4. Show missing coverage before showing a ranking that depends on the missing data.
  5. Use licensed market data when survivorship, delistings, corporate actions, or index membership matter.

Next Ingest Work

  1. Seed pulls now cover labor, prices, payroll jobs, FRED macro and credit rows, NAEP Grade 4 scores, Treasury debt, Treasury deficit, USAspending obligations, Cboe VIX, Voteview polarization, FEC candidate-master parsing, Federal Register executive orders, nonprofit search, Internet Archive records, and Hugging Face dataset search.
  2. Next snapshot targets: FEC transaction parsing, OpenSecrets/TAP influence data, CourtListener with credentials, FBI CDE, NAEP long-term trend and subgroup tables, ACLED, Bridging Divides, GDELT with rate control, legal trackers, and election-threat datasets.
  3. Extend the source-health script from URL reachability to expected columns, last successful fetch, and schema checks.
  4. Map ledger mechanisms to data targets so each score shows which measurements can raise or lower it.
  5. Add historical-market vendor notes before publishing all-history market rankings.
  6. Add a public changelog whenever a data pull changes a card score or era ranking.
