Taxes and Happiness - Details


Planets —> Taxes —> Details

Taxes, happiness, population and planetary structures are all related in a complex system. This page tries to describe the relationships.

Total taxes collected are the sum of colonist taxes collected and native taxes collected. Total taxes collected from a planet can not exceed 5,000 MegaCredits.

Colonist Taxes

If the colonist happiness is more than 30, the taxes collected from the colonists are calculated as follows:

Taxes = (Colonist Clans) * (Colonist Tax Rate) * (Racial Tax Modifier) / 10
The following should be kept in mind when working with colonist taxes:

Colonist Happiness

The Happiness score must not be higher than 100, but can be negative.

The new colonist happiness value is calculated as follows:
(New Happiness) = (Old Happiness) + TRUNC((1000 - SQRT(Colonist Clans) - 80 * (Colonist Tax Rate) - ABS(BaseTemp - Temperature) * 3 - (Factories + Mines) / 3 ) /100)

Colonist happiness is also decreased by combat involving orbiting starships.

The following should be kept in mind when working with colonist happiness:

Colonist Maximum Population

The maximum number of colonists that can live on a planet without requiring supplies, depends on the race and on the planet's temperature.

Crystals

The maximum number of Crystal clans that can live on a planet without relying on supplies, or decreasing, may be computed as follows:
(Maximum Population) = (Planet Temperature) * 1000

Birds, Cyborg, Empire, Federation, Lizards and Privateers

For planets with a temperature of more than 84°W, the maximum population can be calculated as follows:
(Maximum Population) = TRUNC((20099.9 - (200 * (Planet Temperature))) / 10)

For planets with a temperature of less than 15°W, the maximum population can be calculated as follows:

(Maximum Population) = TRUNC((299.9 + (200 * (Planet Temperature))) / 10)

For the remaining planets, the maximum population can be calculated as follows:

(Maximum Population) = ROUND( SIN(3.14 * (100 - (Planet Temperature)) / 100) * 100000);

Colonies, Fascists and Robots

On hot planets, the maximum population for the Colonies, Fascists and Robots won't fall below 60 clans. Beyond this number of clans, they will need to eat supplies.

Rebels

On hot planets, the maximum population for the Rebels won't fall below 60 clans. Beyond this number of clans, they will need to eat supplies. In addition, for planets with a temperature below 20°W, the maximum population for the Rebels is 90,000 clans.

Colonist Population Growth

The population growth of colonists depends on the race, the planet's temperature, the colonist's happiness and the number of planetary structures.

General

In addition to the racial characteristics relating to population growth, there are several limits and modifications that apply to all races.

Crystals

Under most circumstances, the Crystal population growth can be calculated as follows:
(Population Growth) = (Planet Temperature) / 100 * (Colonist Clans) / 20 * 5 / ((Colonist Tax Rate) + 5)

If the Improved Desert Habitation advantage is enabled, the calculation becomes:

(Population Growth) = (Planet Temperature) * (Planet Temperature) / 4000 * (Colonist Clans) / 20 * 5 / ((Colonist Tax Rate) + 5)

Other Races

For non-Crystal colonists, the population growth for planets with a temperature between 15°W and 84°W can be calculated as follows:

(Population Growth) = ROUND( SIN(3.14 * (100 - (Planet Temperature)) / 100) * (Colonist Clans) / 20 * 5 / ((Colonist Tax Rate) + 5))

Cyborg

Before the population growth, the Cyborg will assimilate natives. Each colonist clan will convert up to 1 clan of natives to 1 clan of Cyborg. The population growth will be based on this expanded population.

Colonist Overpopulation

If the planet/planetoid has more population that the maximum, the excess population will either need to have supplies present, or some of them will die.

The number of clans that can be supported by supplies can be calculated as follows:

(Clans Supported By Supplies) = ROUND((Planet Supplies) / 4)

Overpopulation in excess of that which can be supported by supplies will be reduced. The number of clans that will die can calculated as follows:

(Clans Killed) = CEIL(((Present Clans) - (Maximum Population) - (Clans Supported By Supplies)) / 10)

If colonist clans are killed due to overpopulation, it will occur after assimilation. In addition, if any population is killed due to overpopulation, supplies will be consumed according to the following formula:

(Supplies Consumed) = 1 + TRUNC((Native Clans) - (Maximum Population) / 400)

Native Taxes

If the native happiness is more than 30, the taxes collected from the natives are calculated as follows:

Taxes = (Native Clans) * (Native Tax Rate) * (Planet Tax Efficiency) / 10

The following should be kept in mind when working with native taxes:

Native Happiness

The new native happiness value is calculated as follows:

(New Happiness) = (Old Happiness) + TRUNC((1000 - SQRT(Native Clans) - (Native Tax Rate * 85) - TRUNC((Factories + Mines) / 2) - (50 * (10 - Native Government Level))) / 100) + (Native Race Bonus) + (Nebula Bonus)

Native happiness is also decreased by combat involving orbiting starships.

The following should be kept in mind when working with native happiness:

Native Maximum Population

The maximum number of natives that can live on a planet depends on the race and on the planet's temperature.

Siliconoids

The maximum number of Siliconoid clans that can live on a planet may be computed as follows:
(Maximum Population) = (Planet Temperature) * 1000

Other Races

For the other races, the maximum population can be calculated as follows:
(Maximum Population) = ROUND( SIN(3.14 * (100 - (Planet Temperature)) / 100) * 150000);

Native Population Growth

In addition to the racial characteristics relating to population growth, there are several limits and modifications that apply to all races.

Siliconoids

The Siliconoid population growth can be calculated as follows:
(Population Growth) = (Planet Temperature) / 100 * (Native Clans) / 20 * 5 / ((Native Tax Rate) + 5)

Other Races

For all other native races, the population growth can be calculated as follows:
(Population Growth) = ROUND( SIN(3.14 * (100 - (Planet Temperature)) / 100) * (Native Clans) / 25 * 5 / ((Native Tax Rate) + 5))

Conquest and Happiness

When a planet is conquered, the happiness of the conquering colonists is set at 100%. Native populations will suffer a reduction in numbers and planetary happiness which will vary depending on the method of conquest.
