What impact does data coverage have on differentials?
Differentials are calculated from the same compensation data that is used for survey benchmark reporting.
- Differentials for each location are based only on data that is recorded at each location, using the filters you have selected.
- To reduce the impact of varying distributions in seniority between locations, the differentials are normalized across levels.
- Where there is limited coverage for selected levels in a selected location, this will be highlighted (yellow exclamation as seen below) to the user, with the option to switch on Smart Differentials.
How can I check the data coverage at each Location for the filters I have applied?
A summary of Data Coverage is included next to the Differentials panel - this highlights if any of the selected locations have low data coverage:
Option to select "More Details" for a breakdown of the data available in each location:
Within the differentials panel, hovering the mouse over each location bar will also provide a summary of coverage across jobs and levels within that location.

Where there is insufficient data to include a level in the differential calculation, this will also be highlighted in the tooltip.

Where a significant number of levels have insufficient data to include in the differential calculation, this will be highlighted on the differential chart (a differential will be calculated using the data available).

For some locations, based on the filters applied, there may be insufficient data to calculate a differential at all. This will also be highlighted on the differential chart.
