FEW index scoring of GCC by country 2018

RAND’s FEW Index is a composite measure combining country scores for food, energy, and water into a single score for overall resource vulnerability. Each measure is itself a composite score of sub-factors for availability – the extent to which a population is provided adequate resources to support its needs for a particular resource – and accessibility – the distribution of a particular resource across society. The FEW Index ranges from 0.0 (lowest security) to 1.0 (highest security).
It is important to recognize that the FEW Index values are calculated based on the entire population of the country. This fact is particularly salient in GCC countries, where the share of expatriates in the total population ranges from more than 30% in Saudi Arabia to more than 80% in Qatar and the UAE.
