We have heard many times that Tanzania is on the verge of overtaking Kenya to become the largest economy in East Africa.
Some of the numbers thrown around are 2 years, 5 years, soon etc. However, all of these are made up.
If both countries maintain their current growth rates, it will take at least 21 years for Tanzania to overtake Kenya.
This calculation is based on Tanzania's 7% annual growth rate and Kenya's 5%.
(Note that Kenya's actual growth rate is usually higher than that, around 5.6%. If Kenya grows at a constant 5.6%, the 21 years increase to 30 years.).
For the 21 year estimate to hold, these figures must remain consistent. i.e. if Tanzania grows at below 7% or Kenya grows at higher than 5%, the number of years Tanzania requires to close the gap can shoot up considerably.
How did I arrive at these figures?
Using a savings interest calculator, using the 2017 IMF GDP figures.
i.e.
Kenya - $75 billion
Tanzania - $51.1 billion
If both countries maintain the growth rates, this is how the GDPs will look like in 2038 (the year Tanzania overtakes Kenya).
Tanzania - $211.58 billion
Kenya - $208.95 billion
Assuming we work with the 2015 figures, where Tanzania's GDP was $44.9 billion and Kenya's was $63.4 billion, (maintaining % growth at 5% of KE and 7% for TZ) it will take 19 years for Tanzania to overtake Kenya.
However, the reality is that to grow at a constant % every year is impossible for any country. There will be ups and downs. Therefore, while we can use mathematics to predict that TZ will most likely not overtake Kenya before 2038, it is likely it will not even happen in most of our lifetimes.
