ABOUT QATAR
Qatar is a peninsula of 11.437 sq. Km. located halfway down the west coast of the
Arabian Gulf. The Emir, His Highness Sheikh Hamad Bin Khalifa Al Thani, is the ruler
of Qatar and is the head of the constitutional authorities, holding both legislative and
executive powers.
Oil and gas have given Qatar one of the highest per capita incomes in the world and
made it one of the fastest-growing economies. Displaying an enlightened approach to
prosperity, Qatar is channeling its wealth not into trophy assets but into funding the
advancement of culture, science, and education. Its strategic path towards a posthydrocarbon economy will be through a vibrant, knowledge-based society.
Energetic and ambitious, the State of Qatar has emerged from virtual anonymity to
become one of the most forward-thinking nations in the Middle-East, with increasing
regional and global influence. Latest estimates put Qatar’s population at more than 1.5
million.
By 2030, Qatar aims to be an advanced society capable of sustaining its development
and providing a high standard of living for all of its people. Qatar’s National Vision defines
the long-term outcomes for the country and provides a framework within which national
strategies and implementation plans can be developed.
