"Irregular migration poses a considerable problem for South Africa in migration management, population planning, infrastructure development, resource management, governance, social services, economic development and security. A government can only work with what it knows, with a reasonable margin of error. By its nature, irregular migration creates many unknowns. Where entry into South Africa is clandestine or fraudulent, no proper account can be kept of the migrant’s presence, movement, identity, nationality, health status or activities. Without the ability to measure the problem, the ability to address it remains elusive."
