Annotation
All sampling plans have at least one stage. Stages are used to reduce the size of the survey population frame from which to identify sampling units. For instance, the US Current Population Survey samples geographic areas first before identifying households to contact within those areas. Cost and sampling error considerations weigh heavily in these decisions.

Content Element Detail (all declarations; defined within this component only; 8/15)
FrameRequirements
Type:
r:StructuredStringType, complex content
Describes the minimum requirements of the frame needed to use this sample stage. For example, if a stratification by age is specified in the stage the sample frame would need to support this stratification.

<xs:element minOccurs="0" ref="FrameRequirements"/>

RecommendedFrameReference
Type:
r:ReferenceType, complex content
Identifies a specific sample frame or frames appropriate for this plan.
XML Source (w/o annotations (1); see within schema source)
<xs:element maxOccurs="unbounded" minOccurs="0" ref="RecommendedFrameReference"/>

SamplingUnit
Type:
r:CodeValueType, simple content
Sampling unit for this stage

xs:string

<xs:element minOccurs="0" ref="SamplingUnit"/>

SelectionProbability
Type:
r:StructuredStringType, complex content
If known and available, provide the selection probability for each sampling unit. This is one number for equal probability sampling, such as SRS. For PPS, a description of the size criterion is needed. For other unequal designs, a description of of how the probabilities are assigned is needed.
XML Source (w/o annotations (1); see within schema source)
<xs:element minOccurs="0" ref="SelectionProbability"/>

SplitCondition
Type:
r:StructuredStringType, complex content
Condition for using this stage. Use only when multiple top level stages are used.
XML Source (w/o annotations (1); see within schema source)
<xs:element minOccurs="0" ref="SplitCondition"/>

Stratification
Type:
StratificationType, complex content
Describe all stratifications here. Note that each stratified group will be sampled using the same sampling plan. For example stratifying a state by ZIP Code areas in each of 5 mean income quintiles and then doing a random sample of the households in set of ZIP Codes. Allows for oversampling of identified subpopulations.
XML Source (w/o annotations (1); see within schema source)
<xs:element maxOccurs="unbounded" minOccurs="0" ref="Stratification"/>

SubStage
Type:
SubStageType, complex content
A substage assumes that its sample frame is the result of its parent stage.
XML Source (w/o annotations (1); see within schema source)
<xs:element maxOccurs="unbounded" minOccurs="0" ref="SubStage"/>

TypeOfPlan
Type:
r:CodeValueType, simple content
Indicate PlanCode if different from parent. Note that all strata resulting from the stratification process must use the same sampling plan.
