ERI does not provide access to historical software databases. Quarterly datasets are licensed for use during their quarterly effective date only. Subscribers may wish to purchase past publications of the Geographic Reference® report, a hard copy publication, to review general annual changes with the following caveats:
Pay Rates
Please note that ERI does not recommend utilizing our products for historical analyses of pay rate inflation. Due to changes in methodology and survey population over time, such use is inadvisable. To determine salary inflation rates by market it is necessary to track a consistent survey population over time. An individual area survey with consistent methodology is an example of a publication more suitable to this purpose.
Also, please note that the Salary Assessor® (SA), Executive Compensation Assessor® (XA), and Nonprofit Comparables Assessor™ (CA) software database Salary Planning Date and/or Valuation Date feature allows subscribers to trend current quarterly pay data backwards and forwards through time. In other words, the software trends the most recent data to the selected date; it does not pull data from a historical database. Static historical data is accessible for a variety of years in the form of Form 990s, Proxies and 10-Ks which can be downloaded via CA and XA.
Cost of Living
Please note that ERI does not recommend utilizing our products for historical analyses of cost-of-living inflation. Such use is inadvisable due to changes in methodology over time, such as revised area and cost category definitions, and changes in survey population resulting from the addition and removal of various sources and data. To determine cost of living inflation rates by market, it is necessary to track a consistent survey population over time. An individual area survey with consistent methodology, such as the Bureau of Labor Statistic's Consumer Price Index (CPI), would be more suitable to this purpose.
