nationally

Nationally is an adverb meaning “in a national or countrywide manner” or “across the nation.” It describes actions, conditions, or phenomena that pertain to the entire country rather than a region or locality. The word is formed by adding the -ly suffix to national, which derives from Latin nationalis via Old French into English.

Etymology and grammar: Nationally is the adverbial form of national. It should not be confused with nationwide, which can function as an adjective (a nationwide program) or as an adverb (a program funded nationwide). Nationally emphasizes the national scope or policy rather than just geographic reach, and it is common in formal, policy, statistical, or academic writing.

Usage: Nationally is widely used in policy discussions, research, and government or media reporting. Examples include: “The census data were nationally representative,” “The reform was implemented nationally,” and “Nationally published statistics show a gradual decline.” In journalism and official documentation, nationally often signals a countrywide scope without taking a regional emphasis.
