Key figures

What the numbers say

In 2021, Iran, Islamic Rep.'s liner shipping connectivity index (maximum value in 2004 = 100) fell 0.16 on 2020 (from 31.24 to 31.08).

This year's change was 0.1 standard deviations below that average, so it was an ordinary year: it sits within the range of normal year-to-year movement.

On record, the biggest yearly rise was 13.16 in 2020 and the biggest yearly fall was 17.3 in 2018. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2012 to 2021 there is no clear straight-line trend: a straight line explains 14% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures

The Liner Shipping Connectivity Index captures how well countries are connected to global shipping networks. It is computed by the United Nations Conference on Trade and Development (UNCTAD) based on five components of the maritime transport sector: number of ships, their container-carrying capacity, maximum vessel size, number of services, and number of companies that deploy container ships in a country's ports. For each component a country's value is divided by the maximum value of each component in 2004, the five components are averaged for each country, and the average is divided by the maximum average for 2004 and multiplied by 100. The index generates a value of 100 for the country with the highest average index in 2004. . The underlying data come from Containerisation International Online.

Limitations: Data on trade facilitation are drawn from research by private and international agencies. Most data are perception-based evaluations by business executives and professionals. Because of different backgrounds, values, and personalities, those surveyed may evaluate the same situation differently. Caution should thus be used when interpreting perception- based indicators. Nevertheless, they convey much needed information on trade facilitation.
