Growth Rate / Improvement Builds

[Stickyman]

Two questions (I play normal speed).

1. What is the extra food required TO GROW each additional point of population?

2. How fast do workers build improvements, and how much of that is related to terrain type? For example, does a farm on the plain take as much time as a mine on a hill?

Thanks in advance for any information that can be provided.

The time it takes for each thing is different on the different speed levels. I don't know the exact times, but you could quickly make the list yourself, since you can see how long it takes when you make a worker build an improvement. Also while it's building it, you can hover over the worker and see a number in ( ), which tells the number of turns left
