Como é que se diz isto em Inglês (RU)? How can I express the speed of economic growth? thanks a lot.

See a translation

You can just say Economic Growth to define the growth itself. I.e. Growing or declining.

The rate of the speed is further examined by stating if it is slow or rapid.

So for example, if the rate is increasing quickly, then it is growing rapidly. You can also say that it is growing exponentially, if it is increasing by more than 2 times the level for the same period in the year before.

If it is declining, then the economy is shrinking. If it is declining slowly, then it is steadily declining.

If the economy is neither growing or shrinking, then it is stalling (However, that is extremely rare to see).
