There are several needs that must be provided for to satisfy one's population. They are:

• Food
• Drink
• Lifestyle
• Community
• Activity
• Information
• Participation

The needs of your population gradually increase once the population reaches certain civilization level or a certain number of inhabitants is reached (the second category are not actually "needs" but "wants"). The "wants" of a certain civilization level become part of the "needs" of the next one. The first level of civilization (Eco Worker, Tycoon Worker and Lab Assistant) start with only 2 needs: Fish and Community.

The needs can be divided into 2 categories: Ones that are satisfied by goods, and ones that are satisfied by buildings:

• Food, Drink and Lifestyle are satisfied by goods that are present in the island's warehouse. When these goods are depleted, the satisfaction of the population will drop and eventually hit 0% (limited to the good in question). Depending on whether the need is a "want" or a real "need", the tax levels of a certain civilization level will move to the left or the population of said level will grow angry and start to leave the city.

• Community, Activity, Information and Participation are all satisfied by placing public buildings. As long as a house lays inside of the "radius" of these buildings, and both are connected by a road, the needs are satisfied.
• It is worth noting that the needs of Tycoons are more drastically affected by available goods than ecos. A shortage of goods would cause tycoons to stop advancement while Ecos have a delay before anger.
• Note that any completed Monument will provide Community, Activity, Information, and Participation for ALL Population types, but a Monument foundation will only provide Community. Example: you can build an Eco city around a Corporate Headquarters.
