Configuration files for non-US locations can be found in the Synthea-International repository. If you create configuration files for other locations, please consider submitting those to the Synthea-International repository.

By default, Synthea contains demographics, zip codes, providers, names, and costs for the entire United States, post-processed from publicly available files.

You can modify these files or have Synthea use alternative files by altering the src/main/resources/synthea.properties file:

# Abridged synthea.properties file
# Default demographics is every city in the US
generate.demographics.default_file = geography/demographics.csv
generate.geography.zipcodes.default_file = geography/zipcodes.csv
generate.geography.country_code = US
generate.geography.timezones.default_file = geography/timezones.csv

# Default provider files (1 of 10 files)
generate.providers.hospitals.default_file = providers/hospitals.csv
generate.providers.primarycare.default_file = providers/primary_care_facilities.csv

# Payers
generate.payers.insurance_companies.default_file = payers/insurance_companies.csv
generate.payers.insurance_companies.medicare = Medicare
generate.payers.insurance_companies.medicaid = Medicaid
generate.payers.insurance_companies.dual_eligible = Dual Eligible

# Default costs, to be used for pricing something that we don't have a specific price for
generate.costs.default_procedure_cost = 500.00
generate.costs.default_medication_cost = 255.00
generate.costs.default_encounter_cost = 125.00
generate.costs.default_immunization_cost = 136.00

You can find detailed instructions on each of these file formats on the Synthea Wiki:

Abridged Example for Shrewsbury, Shropshire, United Kingdom

Configuration files for this example can be found in the Synthea-International repository, in the example folder. If you create configuration files for other locations, please consider submitting those to the Synthea-International repository.

Demographic Data

Districting and addresses in the United Kingdom differ from the United States. Let's start with the demographics file:

Geographic Data

Now that we have provided new demographic data, we need to provide geographic data for the area we are modeling. So, we need to create postal codes suitable to Shrewsbury, so we edit the zip codes file:

Zipcodes File

,USPS,ST,NAME,ZCTA5,LAT,LON
0,West Midlands,WMS,Shrewsbury,SY1,52.7081,-2.7549
1,West Midlands,WMS,Shrewsbury,SY2,52.7083,-2.7546
2,West Midlands,WMS,Shrewsbury,SY3,52.7089,-2.7543

And then we also need to set the timezone for each "state" (or equivalent):

Timezones File

STATE,ST,TIMEZONE,TZ
West Midlands,WMS,Greenwich Mean Time,GMT

Provider Data

Next, we need to provide at least one hospital for our Salopians, so we edit the hospitals file and the primarycare file:

Hospitals File

,id,name,address,city,state,zip,county,phone,type,ownership,emergency,quality,LAT,LON
0,010001,Royal Shrewsbury Hospital,Mytton Oak Rd,Shrewsbury,WMS,SY3 8XQ,Shropshire,01743261000,NHS Teaching Hospital,Government - Hospital District or Authority,Yes,5,52.7091,-2.7931

Payer Data

We are almost done. We want to make sure our Salopians get to take advantage of the National Health Service. So we need to edit a few more parameters.

# Abridged synthea.properties file
# Payers
generate.payers.insurance_companies.default_file = payers/insurance_companies.csv
generate.payers.insurance_companies.medicare = National Health Service
generate.payers.insurance_companies.medicaid = National Health Service
generate.payers.insurance_companies.dual_eligible = National Health Service

And the insurance companies file:

,id,name,address,city,state_headquartered,zip,phone,states_covered,services_covered,deductible,default_coinsurance,default_copay,monthly_premium,ownership
0,10001,National Health Service,Richmond House 79 Whitehall,Westminster,Greater London,SW1A 2NS,111,*,*,0,0.0,0,0,Government

Wrap Up

For now, let's leave the names and cost files as-is. We're ready to generate data, but there is one last cosmetic change we need to make. In this example, we're generating the United Kingdom (UK), instead of the default United States (US). Let's change the country_code in synthea.properties so generated postal addresses look correct:

generate.geography.country_code = UK

Now, let's generate some data.

./run_synthea -p 1 "West Midlands" Shrewsbury

Check the FHIR output of Jeanine128 Gleason633 (you might have a different patient):

          }
        ],
...abridged...

We did it! We've generated Jeanine128 Gleason633 from Shrewsbury in the United Kingdom.

If you look at the FHIR data carefully, you'll notice a few oddities. First, Jeanine128 has a Social Security Number (SSN) and a phone number that looks suspiciously like it is in the United States. Also, the FHIR records do not use FHIR Profiles from NIH. So, localization in Synthea is not fully solved, and in particular profile conformance is a remaining challenge.
