väestötutkimuksin

väestötutkimuksin is the instrumental plural form of väestötutkimus, a Finnish term meaning population or demography. In scholarly Finnish, väestötutkimuksin is used to reference evidence, conclusions, or analyses that come from population studies rather than experimental or clinical data. The construction signals the means by which findings were obtained.

Väestötutkimus (demography) is the study of the size, structure, and dynamics of populations. It covers variables such as births, deaths, aging, migration, and spatial distribution. Research relies on a range of data sources and methods, including population registers, censuses, vital statistics, longitudinal surveys, and demographic modeling. The instrumental form väestötutkimuksin indicates that a statement is based on such population data and analyses.

Applications of väestötutkimuksin-informed research span policy planning, social and economic analysis, health and welfare planning, urban development, and labor market studies. It is used to examine fertility trends, aging populations, migration patterns, and inequalities, and to support cross-national comparisons and projections.

In Finnish scholarly language, väestötutkimuksin functions as a device to attribute findings to population research. It complements broader terms like väestötiede (demography) and väestötutkimus, and is commonly seen in academic writing when discussing evidence derived from population data.
