Prosenteiltaan

Prosenteiltaan is a Finnish adverb meaning in percentage terms or by percentage. It is used to describe data or comparisons that are expressed as percentages rather than absolute numbers, emphasizing the relative share of a whole.

Etymology and form: the word is derived from prosentti (percent) with the elative suffix -ilta, producing prosenteiltaan. While it literally means “from the percentages,” its idiomatic meaning is “in percentage terms” or “by percentage.”

Usage and nuance: prosenteiltaan is commonly used in statistical reporting, economics, journalism, and academic writing when presenting distributions, growth rates, or differences between groups. It highlights relative proportions rather than raw counts. It is related to, but distinct from, prosentteina (as percentages) and prosentuaalisesti (percentually); prosenteiltaan focuses on the composition or change of parts of a whole expressed as percentages.

Examples: a typical usage is that a measurement or change is described prosenteiltaan, such as “Työllisyys on parantunut prosenteiltaan 3,5 prosenttia viime vuodesta.” or “Alueen koulutuksen saaneiden osuus on prosenteiltaan 45 prosenttia, kun koko väestö on 100 prosenttia.” Another example: “Osuudet eri ryhmien välillä ovat prosenteiltaan erilaiset.”

See also: related terms include prosentti, prosentteina, prosentuaalisesti, and tilastollinen raportointi. Prosenteiltaan is a practical tool for communicating how large a portion of a total is, without relying solely on absolute numbers.
