docassemble.PovertyScale 2024.0.0

A docassemble extension.

PovertyScale

Poverty scale, updated approximately on an annual basis, to use for calculating income eligibility in the United States.

Just get the JSON file

Justification

https://github.com/codeforamerica/fplapi exists but requires a dedicated server, and hasn't been updated in recent years. At Suffolk we are already maintaining and consuming this information in multiple apps; it's simple for us to maintain the API alongside it.

The intent is that you will run this on your own Docassemble server, but we may maintain a public endpoint at some point. If you run your own Docassemble server, this allows you have one source of truth for both use in Docassemble interviews (without the overhead of the REST call) and for use in any non-Docassemble webapps you may have.

Update frequency

The Federal Poverty Guidelines are updated annually, but not usually published in the federal register until a month or so into a new year. We will try to closely track that update timeline. Pull requests with updated figures are welcome.

Examples

See example and demo in demo_poverty_scale.yml

This package contains a JSON file, federal_poverty_scale.json, which can be referenced directly, as well as a module poverty.py which exports poverty_scale_income_qualifies

REST API

Once this file is installed, you can access it as a REST API with a JSON response. The following endpoints are created on your Docassemble server:

• /poverty_guidelines (same as the JSON file)
• /poverty_guidelines/household_size/ (per-household size)
• /poverty_guidelines/household_size/?state=ak|hi&multiplier=2
• /poverty_guidelines/qualifies/household_size/<household_size>?income=1000&state=AK&multiplier=1.5

You can just use the API endpoint to retrieve the contents of the JSON file, or specify a household size and optional state and multiplier to get a tailored response, with either the income limit for a given household size or a determination that someone's income is below the poverty guideline.

Income is expected to be provided on a monthly basis.
