About this site

Sources

• The laws. Public Law 90-498 (1968), Public Law 100-402 (1988) and 36 U.S.C. § 126, plus 5 U.S.C. § 6103 for the Columbus Day holiday, from govinfo.gov, the Government Publishing Office.
• Proclamations. The list comes from the Federal Register API, which FederalRegister.gov describes like this: “using the FR document number you can get information about any Federal Register document published since 1994.” (FederalRegister.gov, Developer Resources: REST API) We searched it on October 12, 2026; the search and its results are on the proclamations page. Each proclamation's text comes from govinfo.gov's copy of the same Federal Register issue.
• History and dates. The Library of Congress portal and the Census Bureau's 2026 Facts for Features.
• Population. The Census Bureau's Vintage 2025 estimates: sc-est2025-alldata6.csv (state file) and cc-est2025-alldata.csv (county file), with their file layouts. The full extraction recipe, the definition of Hispanic or Latino, and the checks are on the county page. Our extract is counts.csv.

What we quote and what we calculate

Anything in quotation marks is copied word for word from the linked page or file. We copy one Library of Congress sentence with its typo (September18) rather than tidy it.

Things marked Our calculationare our arithmetic:

• Weekdays for September 15 and October 15 in any year, and the date of the second Monday in October.
• Share: Hispanic residents divided by all residents, July 1, 2025.
• Change since 2020: July 1, 2025 compared with the April 1, 2020 estimates base.
• County summaries in the explorer: state sums, how many counties grew, the largest.

How it's checked

Two scripts do the checking, and the site won't build if either check fails. The collector pulls the quotes, the proclamation list and the Census files into one dataset, which is then frozen with a SHA-256 checksum. The checker fetches every source again and compares. Its run on October 12, 2026:

• 44 of 44 source pages fetched.
• 36 of 36 quotes found word for word on their pages.
• 32 of 32 proclamations confirmed: opening line and proclaiming line found on govinfo.gov, and number, signing date and citation matching the Federal Register API.
• Every state (51) and county (3,144) figure recomputed from the two Census files and matched.

The checker's full record, page by page and quote by quote, is published as verification.json. These checks confirm that each quote appears on its page and that each number matches the Census files. They don't judge what a quote means; that part is editorial, and the corrections address below is for when we get it wrong.

What's missing

• Proclamations from 1968 to 1993. They're outside the Federal Register API's coverage, and we haven't collected them from another source.
• A 2026 proclamation. Our Federal Register API search on October 12, 2026 found none.
• Local events are outside this site's scope.
• Puerto Rico and the other territories. The Census county and state files we use cover the 50 states and DC.

Ads, analytics and privacy

This site shows Google AdSense ads and uses Google Analytics to count visits and see which pages are read. Both use cookies; our privacy policy explains them and your choices, including how to opt out of personalized ads.

The year lookup and the county explorer run in your browser. Their form fields have no names, so what you type is never added to a page address or sent to our server by the site's code. To search counties, the explorer downloads counts.csv, the same file for every visitor. A link to one county (such as /counties/#c39035) puts that county's code after the # in the address; browsers don't send that part to the server.
