Abstract: The paper elaborated FAO’s geographic representation system, including the job classification and the methodology for calculating the geographic distribution representation. We collected the data of nationals working for FAO enrolled in geographic representation yearly from 2001 to 2017 and analyzed the trend of change. Then from the realistic and the historical perspectives, we analyzed the geographic representation conditions of main member countries and estimated the influence made by the assessed contribution adjustment to the geographic representation. In view of that China still was a under-represented country in the Secretariat of FAO, we put forward countermeasures like planning to apply for the Director General of FAO, urging FAO to improve the efficiency of recruiting, expanding the recruitment propaganda and establishing a senior talent pool.
