Suggested table definitions for human monitoring data.
Individuals¶
The individuals of a survey are recorded in the Individuals table. Add additional properties like Region, Breastfeeding to further describe an individual. In table IndividualProperties, each property in the Individuals table is described (recommended way). Note that only those properties that are available in the Individuals table are used in module Populations, table Populations or PopulationIndividualPropertyValues to subset the individuals. This is only relevant when the UseData option in the population module is used.
Table aliases: Individuals, SurveyIndividuals, ConsumptionSurveyIndividuals, FoodConsumptionSurveyIndividuals.

Individual properties¶
This table is used to describe the properties used in the Populations or PopulationIndividualPropertyValues table characterising the population (table Populations) and/or the properties used in the Individuals table characterising an individual. Properties like Age, Gender, Region are describing an individual (PropertyLevel = Individual). Properties like Period (for populations) or Month (sampling date for an individual day) are describing an individual day (PropertyLevel = IndividualDay).
