Universal Socio-Industrial Index Rating

The Universal Socio-Industrial Index Rating (aka Socio-Industrial Level or USIIR) is a five-letter code used to provide general statistics regarding a settled world.

Breakdown
Relative to the population (currently present at the time of the rating's application), each system is rated by a five letter code (descending order: A, B, C, D, F), which describes the condition of the world in five specific categories:
 * Technological Sophistication - general level of common technology present amongst the population
 * Industrial Development - level of development of an average industrial complex
 * Raw Material Dependence
 * Industrial Output - general quantity figure, describing the number of factories actually present upon the world, without commenting on the level of sophistication
 * Agricultural Dependence
