  • Civ III Demographics Screen and Statistics

    How are the Civ III Demographic Screen Statistics calculated? Ok, I know how they calculate population (they just add up the cities' populations) and land area (each 'square' is considered 100 square miles), but how about the rest? For example, in a game I am currently playing my German Empire has a total population of 188 million. I have market places, banks and stock exchanges as well as a plethora of other improvements in almost all of my cities and yet the total GNP is stated at only something over 3,500 million (I assume this is in U.S. dollars)! What the hell - that comes out to about $20 per capita - if that were in the real world this particular German Empire would be the poorest country in the world by far! How is the GNP calculated in Civ III? It is also strange that annual per capita income is listed as 8 (again I assume it is U.S. dollars) - which is not even consistent with the total GDP and population. How is this calculated? Same goes for family size, which fluctuates between 1 and 2 children even though the empire is growing fast. Does anybody know the process of calculation of these figures that Civ III uses?

    I think research has been done on this, but I don't remember where.


    I do remember a funny screenshot, though, where a guy had a military service of 40 years and a life expectancy of 37.

      Here is the last word I have for what it is worth:

      F11:

      Approval rating:
      The percentage of your people that are happy. If every single person is happy, you have 100%. If everyone is content it is 50%. Edit: This can be misleading when you get specialists, because the specialists count as only content people. So even if everyone is happy or an entertainer, you won't have 100% approval rating if you have any specialists.

      Rounddown (50% + ((Number of happy citizens) - (Number of unhappy citizens)) / (Total number of citizens) / 2 * 100%)

      Population: Add up all the population you get from the city view from all your cities. Not population points, like size 1, 2 or 3, etc. but the 10,000 or 100,000 you see under the city name.
      Sum(i=1..N) {Pop in City(i)}
      Pop in City = {Sum (j=1..(City Size)) {j} + (Food in Storage) / (Storage Size)} * 10000


      GNP: Total gold in all your cities before corruption takes a bite out of it.
      1 gold= 1 million

      Mfg. Goods: Total unwasted shields in all your cities.
      1 shield = 1 megaton.

      Land Area: # of tiles in your territory * 100.
      1 Tile =100 square miles
      Sea is included in this, but does not help in the territory part of your game score.

      Literacy (%)
      (Citizens who live in a city with a Library + Citizens who live in a city with a University + Citizens who live in a city with a Research Lab) / 3 / (Total Number of Citizens) * 100% + (3% if Literature discovered)
      If every city has just a library you will have 33%, because they are missing the other 2 science buildings.

      Edit: Or live in a city with 1 or more scientific Great Wonders (Great Library, Newtons, SETI, Theory of Evolution, Cure for Cancer, and Internet) Copernicus's does not count because despite it helps science, it isn't given the scientific flag. Having 1 of those wonders counts the same as if they had all the other improvements in the city. Two small wonders (apollo and Intelligence Agency) give you credit for having 50% science in that city. You also get 3% added to your literacy rate when you get the literature tech. No bonus when you get education. Great Library still helps your literacy rate even after it is obsolete.

      Disease (%)
      (Number of Floodplains + Jungle in territory) / (Total Number of territory tiles) * 100%

      Pollution: # of tiles that are currently polluted. 1 ton = 1 polluted territory tile

      Life Expectancy (# of years)
      20 + {(Citizens who live in a city with a Granary + Citizens who live in a city with a Aqueduct + Citizens who live in a city with a Hospital) / 3 / (Total Number of Citizens) * 80}

      Family Size: The average amount of excess food that each city is producing/2. If you have 1 city that is producing 4 extra food, that 4 food would feed 2 people, so your family size would be 2 children. Minimum is 1, hard to say exactly what the max would be. In most cases you won't see this above 2, maybe 3 or 4 if all your cities are extremely rich in food, experiencing a very fast growth period or just put down a alot of railroads on irrigated tiles.

      Military Service: 10 years * # of military units / # of citizens. Military units are units with an attack and defense value, so workers, scouts and princesses don't count. Kings do. So at the start of a mass regicide game you will have a military service of 70 years because of the 7 military units *10 years divided by just your 1 citizen. 0 years if you have no army or you have just a few units, but thousands of population points.

      Annual Income: The number of connected strategic/luxury resource types in your territory. The minimum value is 1 and you get a +1 bonus for your first trade route with another civ. Thanks DaveMcW

      Productivity: The total amount of uncorrupted gold, unwasted shields, and excess food you are producing in all your cities
      (Total Shields) - (Total Waste) + (Total Commerce) - (Total Corruption) + (Net Total Food)

        Thanks! That was very helpful.

        Sometimes the statistics portrayed do not make any sense, but at least I now know how they are calculated.

          I should remember the link. We get asked this question alot. No biggie. It's good info to know. We are happy to provide it.

          Manf. goods, GDP, population, and productivity are the ones I try to be #1 in. The others aren't so important. Though literacy at #1 is always nice as well.
