People today are taller, on average, than their ancestors 100 years ago. This is true for every country in the world.

The data shown below is based on a global study. It reports mean height for adults by year of birth, from 1896 to 1996; in other words, people who had reached their eighteenth birthday from 1914 to 2014.
