NOTES: Labor productivity for transportation measures quality-adjusted ton- and passenger-miles per hour. Quality-adjustment corrects for differences in services and handling, e.g., the difference between flying first class and coach or differences in the handling requirements and revenue generation of high- and low-value commodities. Pipeline labor productivity is measured by output per employee. No data are available for water transportation. Raw data are not available from the sources.
Local trucking includes establishments that generally provide trucking services within a single municipality, contiguous municipalities, or a municipality and its suburban areas.
