regionwide

Regionwide is an English term used as an adjective or adverb to describe something that spans or is applicable across an entire region rather than a portion of it. The term signals scope that covers all jurisdictions, communities, or areas within the defined regional boundary, and is common in policy, planning, and operations.

In government and public administration, regionwide measures apply to all member areas of a region. In public health, a regionwide campaign or alert covers the whole region rather than a single locality. In infrastructure and utilities, a regionwide outage or restoration affects all service areas within the region. In business and information technology, regionwide deployments, licensing, or data policies extend across all regional offices, data centers, or customer bases within the region.

Regionwide is distinct from regional in that it emphasizes the entire region as a unit, whereas regional often refers to subunits within the region. It is also distinct from nationwide, which denotes coverage across an entire sovereign state. The term is most common where geographic boundaries are used to coordinate policy, services, or operations across multiple jurisdictions.
