That's 1.43 cm below the worldwide average of 12.93 cm.

The study behind it
The figure comes from Chrouser et al., 2013, which measured 93 men. Method: measured by clinician.
This study did not record a bone-pressed measurement, which means it will read roughly a centimetre lower than a bone-pressed study of the same men. When you compare this row against a bone-pressed one, part of what you are seeing is the ruler.
With 93 men measured, this is one of the smaller samples in the game and the figure should be read as noisier than the rows resting on thousands.
How it compares
Tanzania ranks #22 of the 24 countries in the game. That is 1.27 cm below the median of this list (12.77 cm).
Both of those comparisons are against a list of two dozen countries chosen by which studies exist, not by any sampling of the world. Treat the rank as a fact about this dataset rather than a fact about the planet.

What this figure is not
It is not a description of any individual man from Tanzania. The spread between individual men inside a single country is several times larger than the gap between any two countries on this list, which means a national average carries almost no information about a person.
It is also not medical advice or a benchmark to measure yourself against. If size is something you have been worrying about, the guide on what the pooled data actually shows is a more useful page than this one, and a doctor is more useful than either.
