Linkedin explains both in the Application Programming Interface (API) documentation and on the website that, to protect users’ privacy, demographic metrics are only approximate.
Because metrics are approximate, you may observe minor inconsistencies when comparing:
- Similar time ranges, for example, reporting on results over 7 days vs. 8 days
- The sum of daily metrics to the full corresponding time period
- Reporting levels, for example, adding campaign level data and comparing it to account level data
To minimize the effect of this approximation, select the highest reporting level you want to view, for example, selecting account level data instead of adding up campaign level data
