The Population UWP code is an indicator of the world's population of Sophonts.

  • This figure represents the exponent (number of zeros) which follow the first population digit (this digit is outlined in the extended data).
  • High Population worlds are generally shown in all caps (e.g. ROUP) on sector/subsector maps.

Description (Specifications)[edit]

Following the example from the UWP page Roup 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.

  • High Population worlds are generally shown in all caps (e.g. ROUP) on sector/subsector maps.
  • Population codes 0 and 1 are special cases, as it is important to distinguish low population from literally zero population. Thus, the entire 1-99 range goes in population code 1.
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 Moderate 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)

History & Background (Dossier)[edit]

In addition, the Population Multiplier digit of the "PBG" UWP element must also be zero to qualify for the Ba trade classification.[1]

Barren Worlds[edit]

"Barren" worlds are those worlds with a Population UWP code of 0, Government code 0, Law level code 0 and a Tech Level of 0. Worlds with such elements in the UWP qualify for the Ba trade classification.
