The Culture Indexby CEA

The Index

One composite. Five measures. Nothing backfilled.

The composite is rebased daily on a 0–100 scale. Every number below is clickable down to its inputs, weights and source coverage. Where fewer than three sub-indices are available, no composite is published and the chart shows a gap.

“Composite Formula”

cultureIndex =
  0.30 * velocity +
  0.25 * spread +
  0.20 * sentimentScore +
  0.15 * commercePull +
  0.10 * durability

Sentiment score is ((valence + 1) / 2) × intensity, rescaled to 0–100. Stance is reported separately and never collapsed into a single positive or negative figure.
