open-civics

Structured contact data for US elected officials — state legislators, county councils, and city councils — scraped weekly and published as npm packages.

South Carolina is fully covered: 170 state legislators and 96 local jurisdictions (every county and incorporated municipality).

Packages

Install via npm:

npm install open-civics            # contact data
npm install open-civics-boundaries # district boundary GeoJSON

Package	What's in it
open-civics	Names, titles, emails, phones, districts for state and local reps
open-civics-boundaries	GeoJSON district boundaries for client-side point-in-polygon matching

What the data looks like

Each local jurisdiction file has a meta block and a members array:

{
  "meta": {
    "state": "SC",
    "level": "local",
    "jurisdiction": "county:greenville",
    "label": "Greenville County Council",
    "lastUpdated": "2026-03-14"
  },
  "members": [
    {
      "name": "Benton Blount",
      "title": "Chairman, District 19",
      "email": "BBlount@greenvillecounty.org",
      "phone": "(864) 483-2474"
    }
  ]
}

State legislator files are keyed by district number with senate/house chambers:

{
  "meta": { "state": "SC", "level": "state" },
  "senate": {
    "1": { "name": "...", "district": "1", "party": "R", "email": "...", "phone": "..." }
  },
  "house": {
    "1": { "name": "...", "district": "1", "party": "D", "email": "...", "phone": "..." }
  }
}

Usage

// State legislators
import scState from 'open-civics/sc/state.json';
const senator = scState.senate["1"];

// Local councils
import greenvilleCounty from 'open-civics/sc/local/county-greenville.json';
const members = greenvilleCounty.members;

// District boundaries (GeoJSON FeatureCollection)
import senateBoundaries from 'open-civics-boundaries/sc/boundaries/sldu.json';
import houseBoundaries from 'open-civics-boundaries/sc/boundaries/sldl.json';
import countyBoundaries from 'open-civics-boundaries/sc/boundaries/county-greenville.json';

Boundary files are standard GeoJSON FeatureCollections. Each feature has a properties.district field matching the district keys in the contact data. Use any point-in-polygon library (Turf.js, Mapbox, etc.) to find which district a user's address falls in.

How scraping works

Data is scraped from government websites using Python adapters — one per site pattern. Five shared adapters handle the most common CMS platforms:

Adapter	Sites	How it works
Revize	~30 cities	Parses bold name / mailto / phone patterns
CivicPlus	~14 counties	Parses staff directory tables with JS-obfuscated emails
TableAdapter	~10 jurisdictions	Auto-detects HTML tables with name/email/phone columns
GenericMailto	~15 cities	Finds mailto links in WordPress/Drupal content areas
DrupalViews	~3 counties	Parses Drupal views-row and person-item patterns

The remaining jurisdictions use bespoke adapters, MASC (Municipal Association of SC), or SCAC (SC Association of Counties) as data sources.

Boundary data comes from the US Census TIGER/Line shapefiles (state districts) and ArcGIS REST services (local districts).

Running the scrapers

Requires Python 3.12+.

pip install -r requirements.txt

# Scrape everything for a state
python -m scrapers --state SC

# Scrape only state legislators
python -m scrapers --state SC --state-only

# Scrape only local councils
python -m scrapers --state SC --local-only

# Scrape state + local, skip boundaries (faster)
python -m scrapers --state SC --skip-boundaries

# Preview what would run without scraping
python -m scrapers --dry-run

# Validate all data files
python validate.py

Automation

Three GitHub Actions workflows keep data fresh:

• Weekly scrape (Mondays 10am ET): Runs state + local scrapers, opens a PR with changes
• Monthly scrape (1st of month 10am ET): Full scrape including boundary rebuilds
• Validation: Runs on every PR touching data/ — auto-merges data-update/* branches if validation passes
• Publish: Weekly npm publish if data changed since last release

Running tests

pip install -r requirements-dev.txt

# Unit tests (fast, no network)
pytest tests/unit/ -v

# All tests including integration
pytest -v

# Refresh integration test snapshots from live sites
python scripts/refresh_snapshots.py

Adding a new state

1. Add a state block to registry.json under states.XX
2. Add email format rules to scrapers/state_email_rules.py
3. Run python -m scrapers --state XX --state-only to pull legislators
4. Add local jurisdiction adapters as needed (see CLAUDE.md for the adapter selection checklist)
5. Add boundary sources to registry.json and run python -m scrapers --state XX --boundaries-only
