aldurshópum

Aldurshópum is the dative plural form of the Icelandic noun aldurshópur, which translates to "age group." In Icelandic, aldurshópur is used to refer to a subset of the population defined by a particular range of ages, and aldurshópum appears when the noun is in the dative case and refers to multiple such groups.

Etymology and form: The term combines aldur (age) with hópur (group). The base form aldurshópur has the plural aldurshópar in the nominative, while the dative plural is aldurshópum. This inflection pattern is typical of masculine noun compounds in Icelandic, where the ending changes to reflect grammatical case and number.

Usage: Aldurshópum is primarily encountered in statistical, demographic, and policy-oriented writing. It is used when describing actions, analyses, or data that pertain to several age groups simultaneously, for example in reports that discuss indicators for aldurshópum 65 ára og eldri or descriptions of programs aimed at various aldurshópum across the population.

Relation to related terms: The singular form aldurshópur refers to a single age group, and the nominative plural aldurshópar denotes multiple groups. The concept is central to demography, public health, and social science, where populations are routinely divided into age cohorts for analysis and planning.
