  "Column TSI_Freight of the BTS dataset \"Transportation Services Index and Seasonally-Adjusted Transportation Data\" on data.bts.gov, which BTS describes as \"a weighted average of monthly data for trucking, freight rail, waterborne, pipeline, and air freight.\"",
  "The index is seasonally adjusted, so one month can be compared with the next. Its reference base is 2000 = 100: RapidShips checked that the twelve 2000 values in the dataset average 100.0.",
  "Changes are RapidShips analysis, calculated from the published values."
 ],
 "limitations": [
  "BTS revises the index as inputs are updated and seasonal factors change; its July 2026 release revised June from 134.9 to 136.6. Always check the current dataset.",
  "For the latest month BTS estimates pipeline and air freight one month ahead of reported data, and it estimated waterborne data for July 2026.",
  "It measures domestic for-hire freight only. It excludes international or coastal waterborne movements, private trucking, courier services and the Postal Service, so it is not a measure of port activity.",
  "National, not New Jersey."
