Population and Prosperity Calculator
Here, you can calculate the prosperity rating and the total population for any combination of houses in your city. If you have built a city and are wondering why your prosperity doesn't go beyond a certain number, you can see here why and what kind of housing you need to get a higher rating.
The numbers behind every input field are the "prosperity points" that house gives you. In short, the total prosperity is calculated by adding up all the points from all houses and dividing it by the number of houses in your city; for more information see our prosperity article.
