[GS] Chopping rain forests for population growth?

[ghoultek]

Question #1: Can one chop rain forests to trigger population growth or reduce the number of turns to a population increase?

Question #2: Does Magnus' innate ability apply to rain forest chops (increasing the amount of food generated)?

Question #3: Is there formula for how much food is needed for each population increase?
(drop me a link if there is a guide that covers this... thanks)

Yes, yes and no idea.

Each turn, the food gets put into a basket then each citizen takes two food out. If there is not enough food, a citizen dies. If there is food left over, it is kept for the next turn. When you hit a threshold, you get another citizen. I'm guessing that chopping rainforest just adds food to that basket, making it sooner that it will grow a citizen, or longer before one dies. It generally won't cause growth in and of itself though; if you wasn't going to get the citizen anyway, you won't support the next one and it will starve.

As for the threshold, it's highly variable with things like housing and amenities. The base formula is apparently given in this thread https://forums.civfanatics.com/threads/formula-thread.600534/ for vanilla is 15+8*n+n^1.5
(n is current population-1). I can't give any assurances to the accuracy though, especially since it's nearly 4 years old at this point. I'm assuming that gives the threshold for growth, and remember that's without modifiers like amenities and housing etc.

You can chop rainforest or harvest stuff like rice, bananas etc. to grow your cities.

Magnus affects all yields from removing features or resources as far as I know.

Growing a city several times in a single turn with Magnus and chops used to be a thing but now they've added an overflow stop so you can't just chop out five pop and five buildings in a single turn.

The growth formula hasn’t ever changed. What’s important to remember though, especially for new cities, is that being one point below your housing cap -there will be no red shortage icon in this case will cut any growth in half. I’m pretty sure it applies to food chops too, just like production benefits apply to production chops.

Founding a city that starts with 2 housing applies this immediately, so make sure you buy a granary first.
