regionwise

Regionwise is an English term used as an adjective or adverb to mean by region or on a regional basis. It denotes that something is considered or reported with reference to geographic regions rather than as a single national or global entity.

It appears in academic, governmental, and professional writing to describe data segmentation, analysis, or comparisons driven by regional distinctions. Regionwise analysis can be applied in fields such as epidemiology, geography, economics, marketing, and public policy. It is commonly used with nouns such as regionwise distribution, regionwise rates, regionwise comparisons, or regionwise planning.

Example sentences illustrate its usage: regionwise incidence rates showed higher values in coastal regions, and regionwise GDP growth indicated divergent trends across regions. In research or planning contexts, regionwise approaches help reveal heterogeneity that might be obscured by aggregate analyses.

Orthography and style: Some sources prefer region-wise (hyphenated) while others accept regionwise without a hyphen. Consistency within a document is advised, and regional or region-wide variants may appear depending on the style guide in use.
