CSI sub-index.

Consumer Transition Index.

Tracks the shift towards plant-based and alternative consumption. A rise lifts the sub-index. This is the only transition-positive metric.

4/101 of the CSI · Transition-positive. Static candidate release as of 21 August 2026. The 2026 label is the nowcast period; the stored period-end timestamp is not a future operational update.

Consumer Transition Index is one of the eight first-class sub-indexes the CSI composes. It maps onto the consumer_transition_score metric, carries a raw priority weight of 4/101 and a transition-positive direction factor. This page drills into its latest value, history, lenses, source-native members and evidence trail. Every value is computed from real sources, carries an explicit data-state label and stays provisional until the benchmark trusted gate passes.

Contribution to the CSI

Raw priority weight: 4/101, that is 4 of 101.
Direction factor: Transition-positive (D = 1). A measured rise lifts the sub-index.
Weighted contribution: 3.86 Provisional, the share this sub-index adds to the composed CSI for 2026.

This direct sub-index rises as the plant-based transition strengthens. A higher reading lifts the CSI.

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.

Canonical sub-index (canonical) · showing

Scope

Artefact lens id: global · member scope: WORLD; the lens id and measured member scope differ. The members are WORLD-scope observations, and the CSI consumes this canonical sub-index.
