US motor carriers, in numbers

Everything below is computed from the carriers currently loaded, not from the full federal register — and that corpus is deliberately mixed: currently active carriers plus ones deactivated within the past year, which are over-represented on purpose so the deactivated case is visible at all. Treat the shares as describing this dataset, never as the share of US carriers. It moves when the corpus does.

How to read these

Every figure is computed from the carriers currently loaded and is recalculated periodically — it is a description of this dataset, not of the federal register as a whole. Counts come straight from what carriers filed on their own MCS-150; we do not correct them.
