Identity population data

Identity population data

The deduplication process uses country-specific reference data files to evaluate the identity information in the input data. The reference data files are called
population files
. When you run a mapping with a Deduplicate transformation, the transformation compares the input data to the population file for the country that the asset specifies.
Data Quality
downloads the population files to the Secure Agent host machine when you install the Secure Agent. You do not need to take any action to download the files.
For more information on population file properties, consult the
Deduplicate Guide
in the
Data Quality
online help.
