How much your GDP will grow next turn. This is increased through policies, and war. Growth is subject to natural decay.
GDP growth chart [part of The Brian Simulator (a.k.a. How to Spend Money on Money and Nothing Else Ever)]
Below are the growth barriers for certain GDP levels (calculated at GLF success rate and price):
|GDP||Growth(negative stability)||Growth(neutral stability)||Growth(positive stability)|
239 growth: This is the highest growth value for which you will remain with the highest growth ever possible after decay, 125 (120 without stability bonus). The same decay is obtained at 201 growth.
444 growth (439 without stability): This is the growth level at which you will remain with NON-NEGATIVE after decay. The golden rule is: the maximum growth value you should ever reach is the one for which you can afford to recover the net decay. It is in no way recommended, but if your name is Brian, this is the maximum value. Going any further makes you have in the long run a lower GDP than if you don't pass this barrier.
