About GroceryPulse (boilerplate)

GroceryPulse is an independent Canadian grocery price intelligence platform co-founded by Sung Ha Hwang, its Research Director and a former applied-AI software engineer at Meta. He leads GroceryPulse's methodology, data infrastructure, quality systems, and research publication.

GroceryPulse tracks a 50-item grocery basket weekly across 22 banners in 13 Canadian cities and publishes the Canadian Grocery Price Index (CGPI). Prices are collected weekly (Thursdays, with an automatic Friday catch-up for any city below 90% store coverage) from roughly 160 active stores; the published series begins June 2026. The published headline index is a chained matched-model weighted Jevons (methodology v2, adopted 2026-06-12): each headline series links week to week over the items priced in both weeks, so week-over-week changes are same-composition by construction. The nine category sub-indices are measured direct against a fixed June 2026 base week (= 100, restated 2026-08-10), so category levels are comparable with each other as change since June 2026. 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from the full observation history under versioned normalization code, methodology changes are dated and documented, and superseded series remain available.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.
