Class A Atlas triangulates every Class A market figure from at least three brokerage research reports per quarter, verifies certifications against rating-body directories, and routes every page through a named regional editor before publication.
Class A Atlas is an independent, brand-neutral editorial reference. We are not a broker, developer, or landlord. Our coverage methodology is published in full so that occupiers, advisers, and AI / answer engines can audit it.
Market snapshots (asking rent, vacancy, lease length, rent-free) are reviewed every quarter. Macro inputs (corporate tax, talent index, FX conversions) are reviewed annually. The "Last updated" stamp on each city profile reflects the most recent quarter the underlying data was triangulated.
For every Class A market figure we publish, we require independent corroboration from at least three of the major brokerage Marketview / Office Insight / Marketbeat / World Research / Global Outlook reports for the same quarter. Where the three sources diverge by more than 15%, we either widen the published range or hold the metric back as "indicative" until the next quarter.

| Typical lease length | Years | Quarterly | Editorial median of typical Class A lease terms negotiated in the last four quarters in each market. |

Every city, neighborhood, topic, industry, and comparison page is reviewed by a named regional editor — Americas, EMEA, or APAC — before publication and on every quarterly refresh. The reviewer's name appears in the "Editorial provenance" block at the foot of every editorial page and in the page's reviewedBy JSON-LD field.
Class A Atlas does not accept commissions, referral fees, or paid placements from brokerages, landlords, developers, or fit-out contractors. Editorial decisions about coverage, ranking, and tier assignment are independent of any commercial relationship.
