Tilastoyksiköittäin

Tilastoyksiköittäin is a Finnish statistical term used to describe data that are organized or reported per statistical unit. A tilastoyksikkö (statistical unit) is the entity about which data are collected and measured in a statistical operation. Common units include individuals, households, dwellings, enterprises, or geographic areas such as municipalities. When results are presented tilastoyksiköittäin, indicators are calculated for each unit and aggregated or compared across units. For example, income can be published tilastoyksiköittäin per household, while employment rates can be reported tilastoyksiköittäin per municipality or per firm.

In practice, the choice of the statistical unit influences the interpretation of indicators and the denominators used. Unit definitions must be consistent over time to allow time-series analysis, and cross-country comparisons (for EU statistics) require harmonized unit concepts. Data collection, sampling frames, and weighting schemes are often built around the chosen unit.

Advantages of tilastoyksiköittäin data include the ability to analyze variation across units, identify regional patterns, and support policy targeted at specific unit types. Limitations include potential definitional incompatibilities between datasets, boundary changes that affect comparability, and the risk of ecological fallacies when misinterpreting unit-level results.

Tilastoyksiköittäin is a core concept in official statistics, underpinning how information is structured and compared across units and over time.
