A Population for which a Statistical Activity is designed to make estimates.
Population for which estimates are desired in a Statistical Activity, though practical considerations may dictate that some units are excluded. If so, the resulting sub-set of units for which information can be obtained is the Survey Population.
A type of Process Input whose content goes into a Process Step and is changed in some way by the execution of that Process Step. Some or all of the content will be represented in the Transformed Output.
Transformable Input is a sub-type of Process Input. Producers of official statistics often conceptualize data (and sometimes metadata) flowing through the statistical business process, having statistical value added by each Process Step and being transformed along the way.
A Process Output (a result) which provides the "reason for existence" for the Process Step.
A Transformed Output is a sub-type of Process Output. Typically a Transformed Output is either a Process Input to a subsequent Process Step or it represents the final product from a statistical business process.
Identifies a narrower meaning for the value in the Contextual String.
The object of interest in Statistical Activities and corresponds to at least one Population.
Here are 3 examples - 1. Individual US person (i.e., Arofan Gregory, Dan Gillman, Barack Obama, etc.) 2. Individual US computer companies (i.e., Microsoft, Apple, IBM, etc.) 3. Individual US universities (i.e., Johns Hopkins, University of Maryland, Yale, etc.)
A Represented Variable that is required to supply information in addition to the identification and measures in a Unit Data Set.
Example: The publication status of an observation such as provisional, revised.
A placeholder in a Unit Data Record to contain the value (Datum) for an Instance Variable with respect to a given Unit.
For example (1212123, 43) could be the age in years on the 1st of January 2012 of a person (Unit) with the social security number 1212123. The social security number is an identifying variable for the person whereas the age, in this example, is a variable measured on the 1st of January 2012. The value can be obtained directly from the Unit or indirectly via a process of some kind.
Contains the specific values (as a collection of Unit Data Points) related to a given Unit as defined in a Logical Record.
For example (1212123, 48, American, United Kingdom) specifies the age (48) in years on the 1st of January 2012 in years, the current citizenship (American), and the country of birth (United Kingdom) for a person with social security number 1212123.
A collection of data that conforms to a known structure and describes aspects of one or more Units.
Example: A synthetic unit record file is a collection of artificially constructed Unit Data Records, combined in a file to create a Unit Data Set.
micro data, unit data, synthetic unit record file
Describes the structure of a Unit Data Set.
For example (social security number, country of residence, age, citizenship, country of birth) where the social security number and the country of residence are the identifying components (Unit Identifier Component) and the others are measured variables obtained directly or indirectly from the person (Unit) and are Unit Measure Components of the Logical Record.

The role that has been given to a Represented Variable, in a Unit Data Structure, to identify the Unit.
For example the person identification number in Norway.
The role that has been given to a specific Represented Variable to hold the observed or derived values related to a Unit as identified by the Unit Identifier Components, in an organized collection of data.
For example age and height of a person in a Unit Data Set
Units by which some quantity is measured.
Here are 3 examples - 1. Kilograms; 2. Count; 3. Dollars
