CSI sub-index.

Animal Headcount Index.

Tracks the size of farmed-animal populations. A measured fall in headcount lifts the sub-index; a rise lowers it.

25/101 of the CSI · Pressure reduction. Last updated 10 Jun 2026.

Animal Headcount Index is one of the eight first-class sub-indexes the CSI composes. It maps onto the g20_livestock_population metric, carries a raw priority weight of 25/101 and a pressure reduction direction factor. This page drills into its latest value, history, lenses, source-native members and evidence trail. Every value is illustrative and carries an explicit data-state label until a reproducible production pipeline certifies a release.

Contribution to the CSI

Raw priority weight: 25/101, that is 25 of 101.
Direction factor: Pressure reduction (D = -1). A measured fall in this pressure lifts the sub-index.
Weighted contribution: 18.37 Provisional, the share this sub-index adds to the composed CSI for 2026.

How to read this: this sub-index is oriented to the CSI, so it FALLS as livestock head-counts RISES. A declining line means the real-world metric is increasing (more animal-agriculture pressure, a lower CSI) — the inversion is what lets it compose into the CSI, and does not mean the activity itself is shrinking.

Lenses

The CSI consumes the canonical sub-index. A lens is a filtered view for inspection and is never counted into the CSI a second time.
