Sign | Concepts | Something that suggests the presence or existence of a fact, condition, or quality. | It is a perceivable object. This object is used to denote a *Concept* as a *Designation*. | |

Statement | Business | A report of facts in an *Instrument* | *Statements* are often included to provide further explanation to respondents. Example:
"The following questions are about your health"

| Statistical Activity |
---|
| Statistical Activity | Business | The set of executed processes and the actual resources required as inputs and produced as outputs to investigate the characteristics of a given *Population* for a particular reference period. It may describe process and resources required to acquire (*Acquisition Activity*), produce (*Production Activity*), and disseminate (*Dissemination Activity*) data in a *Statistical Program*. | A *Statistical Activity* includes the run-time information used to actually execute a set of processes. Activities occur in the context of each *Statistical Program Cycle* and execute a particular *Statistical Program Design*. | |

| Statistical Need |

| Statistical Need | Business | A requirement, request or other notification that will be considered by an organization. A *Statistical Need* does not have necessarily have structure or format - it is a 'raw' need as received by the organization. A *Statistical Need* may be of a variety of types including *Environmental Change* or *Information* *Request*. | The *Statistical Need* is a proposed or imposed change as it has been received by an organization. A *Statistical Need* is a raw expression of a proposed change, and is not necessarily well-defined. A related object - *Change Definition* - is created when a *Statistical Need* is analyzed by an organization. *Change Definition* expresses the raw need in well-defined, structured terms. Once a *Statistical Need* has been received, the first step is to do the conceptual work to establish what it is we are trying to measure. The final output of this conceptual work is the *Change Definition*.
In some cases, the *Statistical Need* can result from the *Assessment* of the quality, efficiency, etc. of an existing process. | |

| Statistical Program |
---|
| Statistical Program | Business | A set of activities to investigate characteristics of a given *Population*. It describes the purpose and context of a set of *Statistical Activities*. | The *Statistical Program* is one of a family of objects that provide the environmental context in which a set of statistical activities is conducted. *Statistical Program* is the top level object that describes the purpose and objectives of a set of activities. *Statistical Program* will usually correspond to an ongoing activity such as a survey or output series. Some examples of *Statistical Program* are: - Labour Force Survey - Multipurpose Household Survey - National Accounts - Demography - Overseas Arrivals and Departures
Related to the *Statistical Program* object there are *Statistical Program Design* and *Statistical Program Cycle* objects that hold the detailed information about the design and conduct of the *Statistical Activity*.
In the case of the traditional approach, an organization has received a *Statistical Need* and produced a *Change Definition* and an approved *Business Case*. The *Business Case* will specify either a change to the design or methodology of an existing *Statistical Program*, which will result in a new *Statistical Program Design*; or a change to one or more existing *Statistical Programs* (for example, to add an additional objective to the *Statistical Program*); or result in a new *Statistical Program* being created.

| Statistical Program Cycle |

| Statistical Program Cycle |
---|
| Statistical Program Cycle | Business | A set of activities to investigate characteristics of a given *Population* for a particular reference period. | A *Statistical Program Cycle* documents the execution of an iteration of a *Statistical Program* according to the associated *Statistical Program Design* for a certain reference period. It identifies the activities that are undertaken as a part of the cycle and the specific resources required and processes used and description of relevant methodological information used in this cycle defined by the *Statistical Program Design.* | |

| Statistical Program Design |

| Statistical Program Design | Business | The specification of the resources required and processes used and description of relevant methodological information about the set of activities investigating characteristics of a given *Population*. Includes the *Statistical Activities* that are required to acquire (*Acquisition Activity*), produce (*Production Activity*), and disseminate (*Dissemination Activity*) data in a *Statistical Program*. | The *Statistical Program Design* is one of a family of objects that provide the operational context in which a set of statistical activities is conducted.
A simple example is where a *Statistical Program* relates to a single survey, for example, the Labour Force Survey. The *Statistical Program* will have a series of *Statistical Program Design* objects that describe the methodology and design used throughout the life of the survey. When a methodological change is made to the survey, a new *Statistical Program Design* is created to record the details of the new design. | |

| Subject Field | Concepts | One or more *Concept Systems* used for the grouping of *Concepts* and *Categories* for the production of statistics. | A *Subject Field* is a field of special knowledge under which a set of *Concepts* and their *Designations* is used. For example, labour market, environmental expenditure, tourism, etc. | subject area, theme |

| Survey Instrument |
---|
| Survey Instrument | Business | A specialized kind of *Instrument* used for the explicit purpose of gathering statistical data. | *Survey Instrument* is a tool used to gather information from a *Data Resource*. It can be applied in several ways using different formats and modes, for example, as paper forms in face-to-face interviews, as online self-administered interviews, as computer-assisted questionnaires in telephone interviews, as electronic templates downloaded from the web and returned via email. The *Survey Instrument* provides a generic description of the data collection form independent of the format and mode.

| Survey Population | Concepts | A *Population* for which information can be obtained in a survey. | A *Population* which can realistically be studied (example: people currently residing in the province of Ontario not in an institution nor in a remote northern location nor temporarily out of the province). The *Survey Population* is therefore often a subset of the *Target Population* | object class |
