Definition
Non-aggregated observations, or measurements of characteristics of individual units.
Context
Microdata set is the result of a survey instance or other data collection instance after unit-level editing and imputation and possible matching with other unit-level data. It organizes unit level data so that relationships between individual units and their characteristics can be identified, so as to allow all forms of aggregation.

This is sometimes called an observation register (see, for instance, B. Sundgren: Guidelines for the modelling of statistical data and metadata, UN Geneva and New York, 1995).

Anonymised microdata are individual statistical records which have been modified in order to minimise, in accordance with current best practice, the risk of identification of the statistical units to which they relate (European Commission Regulation (EC) No 831/2002 of 17 May 2002 implementing Council Regulation (EC) No 322/97 on Community Statistics, concerning access to confidential data for scientific purposes).

Longitudinal microdata sets combine unit-level data from succeeding data collection instances over multiple time periods. Related terms Longitudinal data.
