How are you actually doing the anonymization and aggregation?

Zenefits take the following steps to anonymize and aggregate data:

• We remove any company or individual identifiers.
  
  
• We standardize job titles, experience levels, salaries, industry mapping, and geography mapping
  
  
• If there are less than 5 data points (or if they are all from the same company), then we move to a higher level of abstraction
  
  
• No benchmark data is displayed until an appropriate threshold is reached
