About GroceryPulse (boilerplate)

GroceryPulse tracks a 50-item grocery basket weekly across 22 banners in 13 Canadian cities and publishes a chained Jevons price index (CGPI).

GroceryPulse is an independent Canadian grocery price data project. Prices are collected weekly (Thursdays, with an automatic Friday catch-up for any city below 90% store coverage) from roughly 160 active stores; the series begins 2026-03-30. The published index is a chained matched-model weighted Jevons (methodology v2, adopted 2026-06-12): each series links week to week over the items priced in both weeks, so week-over-week changes are same-composition by construction. Price observations are append-only; the index is recomputed from the full observation history under versioned normalization code, methodology changes are dated and documented, and superseded series remain available. Accuracy is checked two ways: weekly automated re-scrape checks confirm reproducibility and mapping liveness (they re-run the same pipeline, so they are not independent accuracy evidence), and independent browser-based spot audits read prices off the retailer page like a shopper — a stratified monthly audit program whose results will be published on the methodology page as the sample accumulates. Walmart and Costco are not covered. Data and methodology are publicly documented and free to cite with attribution.
