Hamnstat

Hamnstat is a term used in Swedish-language contexts to denote port statistics, the systematic collection, processing, and dissemination of data on activities at harbors and port facilities. It encompasses records on vessel calls, cargo flows, and related performance indicators that together describe how a port functions within the national or regional logistics system.

Scope and data types include: the number of vessel arrivals and departures; cargo volumes by type (containerized, bulk, breakbulk, liquid, dry bulk); container throughput in twenty-foot equivalent units (TEUs); total tonnage handled; dwell times for ships and cargo; berth occupancy and crane productivity; hinterland connections and modal share; and environmental metrics such as port emissions.

Data sources typically include port authorities, terminal operators, shipping lines, customs agencies, and automated data from AIS and port community systems. In many countries hamnstat feeds into national statistical programs and is aligned with international standards such as UNCTAD's port statistics guidelines and Eurostat definitions.

Uses of hamnstat include policymaking, planning and investment in port infrastructure, performance benchmarking, research, and monitoring of environmental and sustainability targets. Timeliness and granularity vary; some datasets are annual while others are monthly or quarterly, with caveats about definitional differences across ports or regions.

Limitations of hamnstat data include data quality and comparability across ports, incomplete coverage of all terminals, confidentiality constraints, and the impact of external events on series stability. Users should consider accompanying metadata that describes definitions, coverage, and revision policy to interpret figures accurately.
