As mentioned in Section 2.1.3, “What happens when you run PyPop?”, The XML file is the primary output created by PyPop and contains the complete set of results. The text output, generated from the XML file via XSLT, contains a human-readable summary of the XML results. Below we discuss the output contained in this text file.

3.1. Population summary

A Population Summary is generated for each dataset analyzed. This summary provides basic demographic information and summarizes information about the sample size.
