Data & official recordsfree
Official US transportation statistics — freight, aviation, border crossings. Download tables as CSVs or grab the report PDFs.
This is the US government's own transportation data — freight movement, aviation delays, border crossings — collected consistently enough to support a notebook tracking trends over time. Tables export as CSV and reports as PDF. Coverage is US-only, so it won't help with international transportation comparisons.
Import into Gemini Notebook
- 1Copy the link above (or a specific page from the site).

Gemini Notebook is a reading tool, not a spreadsheet engine — feed it the written reports and summary pages, not raw CSVs, and ask about what the documents say.
