# Vacancy rate

*Market metric · Global*

## Short definition

The share of office space currently available for lease in a market.

## Full definition

Includes both directly available space (landlord vacant) and [sublease](/topics/sublease-strategy)">sublease space. The headline vacancy rate masks important distinctions: trophy vacancy is currently structurally tighter than broader [Class A](/glossary/class-a) vacancy in most markets.

## Why this matters for Class A leasing

Vacancy rate is part of the market metric vocabulary that institutional Class A occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
