A User-Defined Average represents the average values for more than one location (state/province, county, city). It is "user-defined" in that it is not a standard area of the Assessor Series® area database; it must be created by the user.
User-Defined Averages are not available in the Occupational Assessor®, also called eDOT®.
Please refer to the following Help topics for a specific Assessor Series application:
Straight or Weighted Average? The User-Defined Average function provides a straight average, in which each area is weighed one time, rather than weighted average, in which each area is weighed according to resident population, workforce population, business population, etc.
Alternately, the individual ERI area statistical analysis structures are the result of weighted analyses of survey data. This also applies to the pre-defined countrywide, statewide, and provincewide entries in ERI's area database. For example, if you scroll through the "Input City" list, please note that "Alabama – Statewide, United States" is listed. The pre-defined listings are provided for your convenience and are weighted according to survey population.
You may create a countrywide, statewide or provincewide user-defined average that is a straight average by following the steps to create a user-defined average and including the state, or all counties in a state, or all cities in a state as the areas in your average.
