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
| Rating | Technological Sophistication | Industrial Development | Raw Material Dependence | Industrial Output | Agricultural Dependence |
|---|---|---|---|---|---|
| A | High-tech world | Heavily industrialized | Fully self-sufficient | High Output | Breadbasket |
| B | Advanced world | Moderately industrialized | Mostly self-sufficient | Good output | Abundant world |
| C | Moderately advanced world | Basic heavy industry | Self-sustaining | Limited output | Modest agriculture |
| D | Low-tech world | Low industrialization | Dependent | Negligible output | Poor agriculture |
| F | Primitive world | No industrialization | Heavily dependent | No output | "Barren" world |
