North America container gateway throughput (agent-curated)
Derived coast x month panel over the gateway throughput data: west (LA/Oakland/Seattle-Tacoma), east (NY-NJ/Charleston/Savannah), gulf (Houston), canada-pacific (Vancouver), canada-atlantic (Montreal). Each row gives the number of reporting ports, coast total TEU, the coast's share of covered traffic, 12-month YoY and 3-month momentum on the coast sum, and the 0-100 gateway_momentum_index on coast-level terms. A port missing for a month contributes nothing (never filled). Deterministic in code from the curated port panel; monthly cadence.
Agent-curated monthly TEU panel for 9 North American container gateways (7 US: Los Angeles, Oakland, Oakland, Seattle/Tacoma, New York & New Jersey, Charleston, Savannah, Houston; 2 Canadian: Vancouver, Montreal), one row per port x month. Columns: loaded-import / loaded-export / empty TEU splits where the port publishes them (honest nulls otherwise), split shares, 12-month YoY and 3-month momentum on total TEU, and a documented 0-100 gateway_momentum_index = round(100*(0.6*clip01(teu_yoy_pct/30) + 0.4*clip01((teu_mom3_pct+25)/50))) with neutral 0.5 fill for a missing term (null when both are missing). Per-row source_url + verification_level (official_stats_page / official_press_release / secondary_citing_authority) + preliminary_flag record the provenance. Join on (year_month, port_code / coast / state_code) to time purchase orders, promo calendars, and freight-cost forecasts against import momentum. Caveats: ports revise the latest 1-2 months; split detail varies by port; Halifax is quarterly.
