Video shows timeline analysis of average adult human heights by country for shortest men. Data is representative of the majority of the country.

However, as with any statistical data, the accuracy of such data may be questionable for various reasons:

- Different social groups can show different mean height.

- Some countries may have significant height gaps between different regions.

- Test subjects may have been invited instead of chosen at random, resulting in sampling bias.

- A relatively small sample of the population may have been measured, which makes it uncertain whether this sample accurately represents the entire population.
