Methodology

Scope: published products in this sector and its children. The directory sector shares the submission collection. Domains are deduplicated; parent and child totals are not additive.

Size and concentration use all valid current-month domains. MoM uses domains with valid data in both months and a positive baseline. Missing values remain unknown, never zero.

CR3 above 60% is highly concentrated; 30–60% is moderate; below 30% is distributed. This is not a monopoly or investment assessment. New entrants are domains registered in the three months ending with the observation month, not verified product launches.
