You can create tables that use variables from more than one level. The next table cross-tabulates a person-level variable (gender) with a trip-level variable (purpose). When you use variables from parent and child levels like this, the population level defaults to the level of the lowest-level variable, which is the trip level in this example. This means that each cell in this table shows the number of overseas trips for a particular purpose and the gender of the person who took them. The Base column shows that of the 24 overseas trips that were taken, 11 were taken by males and 13 by females.

The base for the table (24) is the same as the base in the fourth table shown above (which tabulates two trip-level variables at the trip level).
