The line graph illustrates the average height of men in four nations – Denmark, the USA, Great Britain, and France – over a period of two centuries, from 1775 to 1975.
Overall, it is evident that the average height of men in all four countries increased over the given period, with Denmark consistently being the tallest by the end. Conversely, France, which started as the second tallest, ended as the shortest among the group.
In 1775, Danish men were the tallest, averaging around 168 cm, closely followed by the French at approximately 166 cm. Men from the USA and Great Britain were significantly shorter, at about 162 cm and 160 cm, respectively.
Over the next century, by 1875, Danish men maintained their lead, growing to roughly 172 cm. The most dramatic increase was seen in the USA, where the average height surged to about 170 cm, surpassing France and Great Britain. The British also showed a noticeable growth to around 168 cm, while French men experienced a minimal increase, reaching just under 167 cm, making them the shortest of the four by this point.
The trend of growth continued into the 20th century. By 1975, Danish men remained the tallest, averaging approximately 182 cm. American men also grew significantly to about 179 cm, securing the second position. British men reached around 176 cm, whereas French men, despite some growth, lagged behind at approximately 174 cm, solidifying their position as the shortest.
