Data & downloads.
Every figure on Glowpedia's analysis pages as versioned, downloadable datasets — with brand population, exclusions and method. Free to use with attribution under CC BY 4.0.
Each dataset is a frozen version with computation date, rule set and input dates. The JSON file is the compilation with a data dictionary; the CSV carries the row-level basis (the brands behind each figure). The figures are shares of the brands in the sample, never market shares.
Ownership concentration in the encyclopedia: what share of brands belong to a group, which groups own the most, where the groups are based and how ownership events are distributed across the decades.
Countries of origin for the brands in the encyclopedia, and how origin relates to where the brands are actually sold on the five markets we track.
How many brands state an independent certification, which certifications are most common, and how the share differs between countries of origin and product categories. The claims are the brands' own, with quote and source on the hub pages.
Founding years of the brands in the encyclopedia: distribution by decade, the oldest brands, the share of new brands and how the median age differs between countries of origin.
The brands' presence on the five markets Glowjakt and Glowscout track: how many are sold on each market, how many are on all five, which are sold in one country only, and how the markets overlap.
Where the brands were founded, crossed with where their current owner is based. Country of manufacture is not yet in the fact base and will be added once harvested. The figures cover brands with an owner of known country and are shares of the brands in the sample — never market shares.
