This table has a total of six dimensions
Two dimensions are displayed initially in the table: Employment Income & Year
But there are four more dimensions in the background:
Geography, Work Activity, Sex, & Occupation
Drag dimensions to ‘redraw’ the table as you’d like…
Now ‘occupation’ is in the rows instead of the columns…
The new view of the table can be saved in Excel format
Individual dimensions can be adjusted to show different views of the table (e.g. Sex = male)
Formats you may encounter
