For LLM agents

This site is built to be read by language-model agents as well as people.

Markdown pages

Every HTML page has a Markdown copy at the same address with .md in place of .html:

Page	Markdown
https://georgiacivicdata.org/r/index.html	https://georgiacivicdata.org/r/index.md
https://georgiacivicdata.org/r/articles/analysis.html	https://georgiacivicdata.org/r/articles/analysis.md
https://georgiacivicdata.org/r/reference/gcd_rows.html	https://georgiacivicdata.org/r/reference/gcd_rows.md

Each HTML page also names its Markdown copy in its <head>:

<link rel="alternate" type="text/markdown" href="analysis.md">

The Markdown pages hold the same text, code and output as the HTML pages.

llms.txt

llms.txt follows https://llmstxt.org. It holds the home page, then links to the Markdown page of every function and article. The pages to read first:

• Get started: the catalog, names and filters, and the rules of the data.
• Analyzing Georgia data: joining two datasets and pooling rates from counts.
• School zones and places: maps, zone status and locating points and addresses.
• Reference: every function, grouped by task.

Writing code with the package

• Install it with pak::pak("shanejorr/georgia-data-rpackage") and load it with library(georgiacivicdata). There is no API key.
• Find a dataset with gcd_search("plain words") or gcd_datasets(), read it with gcd_describe(name) and gcd_columns(name), then get rows with gcd_rows(name, ...).
• Filters are arguments named after the API’s parameters; gcd_describe(name)$filters lists every one with its values.
• Results are tibbles typed from the dataset’s schema: codes are character, so leading zeros survive, and rates are proportions on the 0-1 scale.
• A missing metric usually means the value was suppressed for privacy, not zero. Never add the all total to its subgroups, and pool rates from their counts instead of averaging them.
• The API itself is documented at https://georgiacivicdata.org/docs, and Georgia Civic Data also runs an MCP server for agents; see the main site.
