Generate a population of 100 but got 124 records in Patients

[aiya6502]

Any clue that how come I got 124 records in patients.csv file after I issued the following command ?
java -jar synthea-with-dependencies.jar -c /{PATH_TO synthea.properties file} -p 100

My JDK version is 11.0.16.1 running on Windows 11 and the Database in using is PostgreSQL 15.0 , and in the synthea.properties:

1. I copied the file from sample one
2. Update "exporter.fhir.export = false" and "exporter.csv.export = true"

Thanks.

The -p switch is a shortcut for generate.default_population:

This is the number of living patients (population size) that Synthea will generate. Synthea will generate patients until the number of living patients reaches this value.

From: See https://github.com/synthetichealth/synthea/wiki/Common-Configuration#generation-settings.

If you have a town with a census population of 100 people, that means 100 living people. In the simulation, sometimes people die. So, they don't count in terms of total population.

If you don't like how that works, you can modify the following settings in synthea.properties:

# Set to true if you want every patient to be dead.
generate.only_dead_patients = false
# Set to true if you want every patient to be alive.
generate.only_alive_patients = false
# If both only_dead_patients and only_alive_patients are set to true,
# It they will both default back to false

Got it, thanks a lot for clarifying this.
