Population
The Population code from the Universal World Profile is the order of magnitude of number of sophonts inhabiting the system. The population is represented on a logarithmic scale, with the population digit showing the number of zeros in the population number.
| Population Codes | ||||||||
|---|---|---|---|---|---|---|---|---|
| Code | Description | Population (where P is the population multiplier) | ||||||
| 0 | None | 0 | ||||||
| 1 | Low | 1 to 99 (P0) | ||||||
| 2 | Low | 100 to 999 (P00) | ||||||
| 3 | Low | 1,000 to 9,999 (P,000) | ||||||
| 4 | Moderate | 10,000 to 99,999 (P0,000) | ||||||
| 5 | Moderate | 100,000 to 999,999 (P00,000) | ||||||
| 6 | Moderate | 1 Million to just under 10 Million (P,000,000) | ||||||
| 7 | Moderate | 10 Million to just under 100 Million (P0,000,000) | ||||||
| 8 | Pre-High | 100 Million to just under 1 Billion (P00,000,000) | ||||||
| 9 | High | 1 Billion to just under 10 Billion (P,000,000,000) | ||||||
| A | High | 10 Billion to just under 100 Billion (P0,000,000,000) | ||||||
| B | High | 100 Billion to just under 1 Trillion (P00,000,000,000) | ||||||
| C | Very High | 1 Trillion to just under 10 Trillion (P,000,000,000,000) | ||||||
Population multiplier
The Population Multiplier digit of the "PBG" gives the first digit of the population number. The total population of a system will be: population multiplier times 10 to the power of population code.
For example, Roup (Spinward Marches 2007) has a population code of 9 and a population multiplier of 3. Thus the population is roughly 3x109 people or 3 billion (3,000,000,000 - three followed by 9 zeros). The actual population will be between 2.5 and 3.5 billion.
Population trade codes
There are four Trade Classification codes associated with the population level of a world
- Ba - Barren
- The system has no population and no evidence of ever being inhabited.
- Di - Die Back
- The system has no population, but there is evidence of previous habitation.
- Lo - Low population
- As on the table above, the world has a population between 1 and 10,000 sophonts.
- Ni - Non-industrial
- As the medium population on the table above, the system has a population between 10,000 and 10 million.
- Ph - Pre-high population
- The system has a population between 100 million and 1 billion
- Hi - High population
- Per the table above, the system has a population over 1 billion sophonts.
