IOM has experienced rapid growth over the past ten years. Key indicators include:
Membership increased from 67 States in 1998 to 125 States in 2009 and continues to grow.
Total Expenditure increased from US$ 242.2 million in 1998 and exceeded US$ 1 billion in 2008.
Field locations (1) increased from 119 in 1998 to more than 430 at present.
Active projects increased from 686 in 1998 to more than 2,030 at present.
Operational staff increased from approximately 1,100 in 1998 to approximately 6,690 at present, almost entirely in the field.
IOM''s structure is highly decentralized and service-oriented. There are currently 18 Missions with Regional Functions (MRFs) serving as resource centres and 7 Special Liaison Missions (SLMs).
Projectization is used by IOM (similar to Activity-based costing), where staff and office costs associated with implementing a project are charged to projects through a time-allocation concept referred to as projectization. Every activity in IOM is assigned a distinct project code. Every project is managed by a project manager to ensure that projects are monitored in a responsible, transparent and efficient manner.
Manila and Panama Administrative Centres: In order to achieve efficiencies and manage growth, IOM has embarked on an exercise to transfer certain functions from Headquarters and other high cost locations to lower cost locations. The Manila Administrative Centre currently provides global support in the areas of finance, human resources management, information technology, staff security, project tracking, health claims processing, etc. The recent establishment of another administrative centre in Panama''s City of Knowledge further strengthens and broadens IOM''s delocalization process.
Total Funding: In 2008, more than 96 per cent of IOM''s funding was in the form of voluntary contributions for projects. The remainder represents the administrative budget, funded from Member State contributions.
Lowest Rate of Administrative Support: To cover its indirect costs, IOM charges 5 per cent on total costs of projects for administrative support. IOM''s support costs are among the lowest of all international organizations.
