National Urban Populations and the Logistics Performance Index
There is a level of proportionality between the share of the urban population and the Logistics Performance Index (LPI); the higher the share of the urban population, the higher the LPI (statistically significant R square of 0.37). The size of each observation is related to the national population living in cities of more than 1 million inhabitants. For instance, China with an urban population at 46% of its total population has a population of 224 million inhabitants living in cities of more than 1 million inhabitants has with a national LPI of 3.49. The positive outliers (above the trend line) are countries having a high dependence on international trade and thus well-developed logistical structures (e.g. Germany, Japan, China, South Korea). The negative outliers (below the trend line) tend to be countries with a more limited participation to international trade with deficient transport infrastructure and governance issues (e.g. Brazil, Russia, Nigeria).
