World Research Institute Logistics Index

A monthly, GDP-weighted diffusion index of logistics-sector activity across 42 economies, aggregated into regional and World readings. A reading above 50 signals month-on-month expansion in goods movement, below 50 contraction (±0.05 counts as no change), with distance from 50 measuring the strength of the move. Country readings are individually researched and cross-verified across independent sources; regional and World readings are GDP-weighted on a US$107.01T (2025) base. Not seasonally adjusted. Published monthly by the World Research Institute. This deposit is the openly published World + regional layer; live data at https://intelligence.worldresearch.org/lgi.
