e.g. Economy would be a parent code and Tourism would be a child code.
NVivo staff suggest that your coding structure have a maximum of 10 top-level codes and be no more than 2-3 layers deep:
It’s better to code things twice or three times rather than have a code such as Negative attitude toward tourism (e.g. instead code Negative attitude and Tourism separately because it allows for greater flexibility in the analysis).
You can then run a query for negative attitudes among one or more other codes (e.g. Negative attitudes toward Tourism or Real estate development).
This is essential if you are 2+ people coding to ensure you are applying your codes the same way.
To create a code in the List View:
Optionally, you can select Aggregate coding from children to include all the references in child codes for a parent code. Click here for a detailed explanation of aggregate codes.
To create a code while coding in Detail View:
Codes can be organized into hierarchies for broader and narrower concepts. For example, Fishing or aquaculture is the child code of Economy (shown in the picture below).
To create a child code (code hierarchy):
Tip: The Hierarchical name field on the New Code dialog box can indicate the hierarchy relationship of your new code.
