Settlement

A settlement is either a single standalone Housing building or, more commonly, multiple Housing buildings built immediately adjacent to each other. This is where the Population lives and where the residents do almost everything: sleep, eat, maintain their hygiene, and enjoy Household Goods and so on. The only except is work in buildings or vehicles.

Services

Each settlement requests services to be provided to increase the comfort of the Population. Only Food supply and Waste collection are essential services. If these services are lacking, critical population decline will occur.

Other services are not essential, and there is no penalty for lacking services. But fulfilling these requests provides a set amount of Unity and/or promotes Health per request. They are helpful in a steady source of Unity, used for Research Lab (and its variants) and outposts such as the Sawmill or Oil Rig. They are also helpful to combat the bad influence of Air Pollution and Water Pollution.

The Population Overview UI pane as seen to the right is accessed by clicking the Population icon at the top-left corner of the game screen and displays the total amount of Unity received from meeting demands.

List of services

All requested services are shown in the following table. A requested amount of each service is in a proportion of the population. And, some of them are also depend on the tire of Housing.

Requested amount of food

The requested amount of food depends on the type of food, and it is a bit complex to calculate the amount. As a simple example, when only single food is provided to settlements, the requested amount of food will be the following value.

Food Category	Food	Requested amount / 60 per 1000 pops
Carbs	Potato	1000/17.0 = 58.82
	Corn	1000/25.0 = 40.00
	Bread	1000/37.0 = 27.03
Protein	Meat	1000/27.0 = 37.04
	Eggs	1000/25.0 = 40.00
	Tofu	1000/41.0 = 24.39
	Sausage	1000/22.0 = 45.45
Vitamins	Vegetables	1000/17.0 = 58.82
	Fruit	1000/23.0 = 43.48
Treats	Snack	1000/13.0 = 76.92
	Cake	1000/29.0 = 34.48

When several food are provided to settlements, the requested amount of each food will decrease, and the total one of all food will be similar to a case of the single food provided. The exact value at version 0.4.9 can be calculated in the following formula.

Requested amount / 60 per 1000 pops = A / (N_c x N)

N_c: Number of provided food category

N: Number of type of provided food in same category

A: Requested amount when only this food is provided (Value in above table)

For example, Potato, Corn, Bread, and Vegetables are provided for 1000 pops:

N_c = 2 (Carbs and Vitamins)

Potato = 58.82 / (2 x 3) = 9.80 / 60

Corn = 40.00 / (2 x 3) = 6.67 / 60

Bread = 27.03 / (2 x 3) = 4.51 / 60

Vegetables = 58.82 / (2 x 1) = 29.41 / 60

Total = 50.39

At version 0.4.10, the above formula is approximately correct, but it has a small error.

Unity and Health bonus by food

Fulfilling food requests provides 1.00 of Unity (A type of food makes no matter). In addition, more Unity will be provided when settlements receive variable food.

Food Category	Food	Unity
Carbs	Potato	0.15
	Corn	0.15
	Bread	0.30
Protein	Meat	0.40
	Eggs	0.30
	Tofu	0.30
	Sausage	0.10
Vitamins	Vegetables	0.20
	Fruit	0.30
Treats	Snack	0.20
	Cake	0.55

For example, Potato, Corn, Bread, and Vegetables are provided:

Unity = 1.00 + 0.15 + 0.15 + 0.30 + 0.20 = 1.80

The Health bonus is 4 times as much as the number of food categories provided to the settlement. For example, Potato, Corn, Bread, and Vegetables are provided:

Number of food category = 2 (Carbs and Vitamins)

Health = 4 x 2 = 8
