Regional Orientation
The regional orientation index tells us whether exports of a particular product from the region under study to a given destination are greater than exports of the same product to other destinations. In other words, it measures the importance of intra-regional exports relative to extra-regional exports.

Select source region:
Select destination region:
Select commodity:
Select year:
 
  
Definition:
The index is the ratio of two shares. The numerator is the share of a country’s exports of a given product to the region of interest in total exports to the region. The denominator is the share of exports of the product to other countries in total exports to other countries.

Range of values:
Takes a value between 0 and +∞. A value greater than unity implies a regional bias in exports.

For further note on this indicator, including an example and formula, see the relevant section of Trade Statistics in Policymaking: A Handbook of Commonly Used Trade Indices and Indicators.
