- 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.

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.
|Code||Description||Population (where P is the population multiplier)|
|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)|
In addition, Marc Miller has stated that the Population Multiplier digit of the "PBG" UWP element must also be zero to qualify for the Ba trade classification.
"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.
