Average penis size in Tanzania 🇹🇿

The figure comes from Chrouser et al., 2013, which measured 93 men. Method: measured by clinician.

This study didn't record a bone-pressed measurement, so it reads roughly a centimetre lower than a bone-pressed study of the same men would. Compare this row against a bone-pressed one and part of what you're 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.

The Tanzanian measurements come from men presenting for voluntary medical male circumcision at three health facilities in the Iringa region. The study's stated purpose was practical rather than anthropometric: sizing circumcision devices and forecasting supply. A sample recruited at a circumcision clinic is not a population sample, and it was never designed to be one. It is here because it is a real, clinician-measured figure, which is more than can be said for most numbers that circulate about this part of the world.

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.

Tanzania has been the daily puzzle 2 times so far. Each of those days has its own archive page.

It doesn't describe any individual man from Tanzania. The spread between individual men inside a single country runs several times larger than the gap between any two countries on this list, so a national average carries almost no information about a person.

Nor is it medical advice, or a benchmark to measure yourself against. If size is something you've 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.
