Containerisation rate, imports, by gateway

tt008.gateway.containerisation-import reported

Share of inbound waterborne cargo WEIGHT moving in containers rather than bulk or breakbulk, by port and month. Oakland runs near 100%; Houston near 38%, the balance being petrochemical bulk.

COVERAGE INCOMPLETE. The 2010-2023 backfill is still loading, so the archive holds twelve months for 2024 and 2025 but only a partial 2010. Any comparison across years today weighs one loaded month against twelve — an apparent rise from 38% to 63% on import containerisation is currently indistinguishable from that loading artifact. Lift when every month from 2010-01 to the last complete month is present, verified by a per-year month count, not by row totals.
