Employees per material

Goal: Add employee data per material.

Approach: Build on the work from Sublayer “1.3. Economic activity - descriptions” and “1.4. Economic activity - figures” and try to become more detailed by finding the number of employees for each material’s relevant NACE codes that were identified in their value chain. More detailed means here that going from a 2 level NACE code to a 3 or 4 level code. Of course, you only need to check for those economic activities that take place in your city. You can follow the same steps as described in GDP, except that you would tag with “EMPLOYEES” in the tags field.
