National GII is not an arithmetic average of every event ever recorded — it sums the active, attributable contributions in the observation period. Each event contributes Pₑ,ₜ = aₑ,ₜ·Mₑ·(Cₑ/100)·nₑ: exposure × magnitude × confidence weight × non-overlap. Confidence enters only here, at the cross-event level, so weakly identified events cannot move the series as much as well-identified ones. The institutional and domain views use the same records and non-duplication rules.
Assembled live by @gii/series from 6 illustrative decisions over 6 periods. GII-US is pre-pilot; not a series of any real government activity.

Institutional views#
Branch rollups partition the events — the Supreme Court appears in its own filter and as one non-duplicated component of the Judiciary. The branch series therefore sum to the national raw measure every period (verified: true).
| Branch | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|---|
| Executive 2 | 0 | 6.336 | 14.784 | 25.808 | 34.72 | 38.12 |
| Federal Reserve 1 | 17.29 | 34.58 | 43.225 | 38.9025 | 30.2575 | 21.6125 |
| Judiciary 2 | 1.4175 | 4.2525 | 23.5875 | 34.905 | 38.205 | 36.7875 |
| Legislative 1 | 7.812 | 23.436 | 35.154 | 39.06 | 35.154 | 31.248 |
Domain views#
Each event is decomposed across its impact domains; a domain filter shows its share, never a multiplied total:
| Domain | 2020 | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|---|
| international_trade | 0 | 0 | 0 | 5.1 | 10.2 | 12.75 |
| nonprofits | 0 | 0 | 0 | 4.25 | 8.5 | 10.625 |
| people_households | 5.04 | 15.12 | 22.68 | 31.66 | 35.6 | 36.31 |
| private_enterprise | 1.3365 | 10.8735 | 33.1985 | 45.411 | 49.799 | 48.4625 |
