Definition: Accession Rate refers to the pace at which new members or entities join a particular group, organization, or system over a specified period. This term is commonly used in various contexts, such as membership growth in associations, subscribers in online platforms, or the addition of new data points in a database. The Accession Rate is a crucial metric for assessing the expansion and popularity of a given entity.
Accession Rate is typically calculated by dividing the number of new additions or accessions during a specific time frame by the total number of existing members or entities. The result is often expressed as a percentage, providing a clear indicator of the growth rate. The formula for Accession Rate is:
Accession Rate = (Number of New Additions/Total Number of Existing Members)×100
This measurement helps organizations and systems track their development and make informed decisions based on the trends in membership or data acquisition.
