Logistics performance index: Overall rank (1=highest performance)
The Logistics Performance Index overall rank reflects perceptions of a country's logistics performance based on the efficiency of the customs clearance process, quality of trade- and transport-related infrastructure, ease of arranging competitively priced international shipments, quality of logistics services, ability to track and trace consignments, and frequency with which shipments reach the consignee within the scheduled time. The ranks range from 1 to 160 (in the 2018, 2016, and 2014 edition; 155 in 2012 and 2010, and 150 in 2007), with a lower rank representing better performance. Data are from the Logistics Performance Index surveys conducted by the World Bank in partnership with academic and international institutions and private companies and individuals engaged in international logistics. The 2018 round of surveys covered close to 6,000 country assessments by around 1,000 international freight forwarders. Details of the survey methodology and index construction methodology are available in Arvis, Ojala, Wiederer, Shepherd, Raj, Dairabayeva, Kiiski: "Connecting to Compete 2018: The Logistics Performance Index and Its Indicators", see Appendix 5 for methodology.
