The world of Anno 1800 is made up of several regions, each of them located in a particular biome (climate zone). Currently in the game, there are four different biomes:
- European temperate forest - present in two regions: The Old World as part of the Anno 1800 base game, and Cape Trelawney as part of Sunken Treasures DLC.
- South American tropical jungle - present in one region: The New World as part of the Anno 1800 base game.
- East-African arid deserts and plains - present in one region: Enbesa as part of the Land of Lions DLC.
- Polar snow-covered taiga - present in one region: The Arctic as part of The Passage DLC.
Each biome has different type of population, buildings, production chains, available fertilies and resources, along with possessing distinctive looks through flora and fauna. Some fertilities and resources are unique to one climate and it is all but necessary to transport the goods produced between regions and climates for the proper development of a player's empire. This by use of trade routes, charter routes, or sending ships to other regions manually.
Each region consists of several islands with an ocean between them. The size of the region, islands arrangement, fertilities, resource dispersal and room available for construction are all based on game settings chosen upon initialization. World generation is affected by game seed as well as all other other settings which can be modified when starting a new match.
The World Map shows all unlocked regions, the ships traveling between them and all available expeditions. From here you can switch between regions, monitor your global trade routes, check out expeditions and send your ships to embark upon them.

The Old World is the first playable region available and should be the region where most of your population is located. It is based on the 19th century Europe.
Population in the Old World is divided into five tiers (six with the Land of Lions DLC: Farmers, Workers, Artisans, Engineers, Investors, and (with the Land of Lions DLC) Scholars. Goods produced in the Old World focus mainly on industrialization, most of them require heavy industry and mined resources such as iron, coal, copper or zinc. Only a few require crop or animal farms and their products like grain or pigs.
Besides yourself and other expanding players (either AI or human) some neutral traders and pirates can also be located in the Old World. Each of them settles a separate special island. Sir Archibald Blake is always present in the Old World while the presence of Madame Kahina, Eli Bleakworth and Anne Harlow is optional.

Population in the New World is divided into two tiers: Jornaleros and Obreros. New World production focuses on farming and its main role is to support the Old World population with goods such as cotton fabric, rum, coffee, gold ore, caoutchouc, oil, pearls, cigars and chocolate.
Depending on the initial game setting, besides yourself and other expanding players (either AI or human), neutral trader Isabel Sarmento and pirate Jean La Fortune can be located in this region. They've settled their own, predetermined island from the start and won't expand.

Cape Trelawney is the third playable region, available with the Sunken Treasures DLC after reaching 700 Artisans and completing a special expedition. The region is very similar to the Old World. What makes it much different is its continental island which allows to create a huge city.
Besides yourself and other expanding players (either AI or human), a neutral trader by the name of Old Nate is located in Cape Trelawney. He's settled his own, predetermined island from the start, won't expand and will provides access to new features: crafting and the salvager.
- See also: Enbesa
The population in Enbesa is divided into two tiers: Shepherds and Elders. Production in Enbesa focuses heavily on crops and farms, with the need to irrigate dry land to make it fertile. Enbesa goods are vital for the new Scholars Old World resident tier that focuses on Research.
- See also: The Arctic
The population in the Arctic is divided into two tiers: Explorers and Technicians. Production in the Arctic focuses on surviving the environment by exploiting the local caribou, seals, whales, bears, geese and huskies for gear and comfort. Once Arctic settlements have managed a certain standard of living, the region's abundance of gold ore, fur - alongside new gas and airship technology - can be imported back to Old World.
Besides yourself and other expanding players (either AI or human), the native Inuit have settled their own predetermined location from the start, won't expand and are willing to trade with you.
- See also: Expeditions
Once Artisans move into one of your cities in the Old World, expedition feature becomes unlocked. The First expedition is always a discovery expedition and completing it rewards with the The New World being unlocked, with a second expedition to unlock Enbesa also unlocked by reaching Artisans if the player has the Land of Lions DLC. After the first expedition is completed, other types of expeditions are unlocked. They are a great source of all types of items, either acquired as final expedition rewards or during randomized events.
All expeditions are marked on the World Map in different locations and climate zones, which along with the expedition type determine possible rewards pool.
