  To get all categories that are related to an entry you would do this:
  
  ```
  {% set allEntries = craft.entries.limit(null) %}
  {% set categoriesInUse = craft.categories.relatedTo(allEntries) %}
  
  ```
  
  If you want to narrow down to a specific category group or any other category property you can do it like so:
  
  ```
  {% set newsCategories = craft.categories.group('newsCategories').limit(null) %}
  {% set entriesWithNewsCategories = craft.entries.relatedTo(allCategories).limit(null) %}
  {% set newsCategoriesInUse = craft.categories.relatedTo(entriesWithNewsCategories) %}
  
  ```
  
  And yes, you probably want to wrap it together with the loop to print the categories in cache tags!
