You can select the analysis Level and thus the statistical units used in your tables and charts. Levels are used when you have data that cannot be represented by a flat file. For example, you might want to view data at the level of entire households, or at the level of individuals within each household.
You can change the analysis level by using the Default level dropdown in the Survey settings modal window. Any new table definitions for the given survey will use the selected global level by default.
You can choose the analysis level for a specific tab definition in the Level property, found in the general properties.
