Methodology

How tiers are assigned

Deterministic public-footprint core (local depth, practice share, seniority mix, public hiring momentum), computed relative to this market's own distribution. Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.

Market scope

25–49 firms earn a tier in New York within this scope (banded).
