When selecting more than one component from the same geographical level, Social Explorer provides a total for these components in the "All Selected Geographies" column. This total is for the available geographies only within the same geographical level. When a value is missing from one or more components from the same geographical level, Social Explorer denotes it with an asterisk (*) in the All Selected Geographies column.
