Description[edit | edit source]
Each of your cities has a "housing limit" that can be understood as a soft cap on your population. When a city's population reaches the number immediately below the housing limit (for example, when your city has 6 housing and 5 population) the city's population grows 50% slower. Once the housing limit is reached, it will grow 75% slower. After a city reaches 5 population beyond its housing capacity it stops growing altogether.
Increasing your Housing can be achieved by the following: Buildings, Civics, Districts, Tile Improvements, access to water: being next to Rivers, Mountains, Lakes, Oasis and some Natural Wonders, by building an Aqueduct, and, lastly, with some Great People.
The Tile on which the city was settled also influences the starting housing limit number. If a city has access to fresh water it starts with +3 Housing. If it has access to the Coast it has +1 housing, and if it has no access to water it gets +0 to housing.
Whenever a Settler is selected, the tiles will be marked with one of 4 colors, depending on their access to water: Red (the Tile is not possible to settle), Grey (The Tile has no access to fresh water), Light Green (The Tile has access to the Coast), and Dark Green (The Tile has access to fresh water).
This is a new aspect to consider when settling new cities: the Water Availability Guide. The Aqueduct District can take fresh water 1 tile away from Rivers and Mountains, providing fresh water to cities, giving a boost of +6 to Housing. Cities that already have access to fresh water gain an additional +2 Housing from Aqueducts.
Additionally Food plays a part in housing. The basic growing principle is that each of your Citizens in a given city uses 2 Food and the remaining food produced is put towards the production of getting the next Citizen (you'll see the number on the left hand side next to the amount of Citizens in your City), so population increases with excess food.
Strategy[edit | edit source]

In the early game (until the Urbanization Civic in the Industrial Era is researched), there are significantly fewer ways to increase housing, and all of them with less effect than the Neighborhood district. Therefore, it is very important to found early cities on tiles with fresh water access, or at the very least, on the coast. Certain basic improvements provide 0.5 Housing: Farms, Camps, Plantations, Fishing Boats, and Pastures. Therefore, it is important to build these improvements around young cities. Aqueducts also provide up to +6 Housing for cities that don't already have fresh water access, and +2 Housing for those that do. However, since the Aqueduct is a district, it will permanently occupy a tile adjacent to your City Center that may be more strategically useful for another district or Wonder.
Once Urbanization is researched, Housing generally becomes less of a problem. The Neighborhood District (or Mbanza) provides anywhere from +2 to +6 depending on the appeal of the tile it is built on. Tiles adjacent to certain features (such as Coast tiles or Natural Wonders) receive bonuses to appeal, while being adjacent to other features (such as Marsh or Industrial Complexes) reduce tile appeal. However, since Neighborhoods are much more flexibly placed than Aqueducts, they are less prone to occupying strategically important tiles you may need to maximize other adjacency bonuses or to build Wonders on.
