How tall can a person get ?
We humans have transformed dramatically in the past century . Our global population has soared from just over a billion to more than seven billion . In developed countries like the US , the average life expectancy has jumped from 45 years or so in the mid-1800s to nearly 80 years in the present day . Our physical changes are the most conspicuous of all . We are now taller than before — roughly 4 inches ( 10 cms ) taller on average than humans were fifteen decades ago .
Industrialized countries like the USA , the UK , Japan etc . have witnessed this average human height increase on a more prominent scale , but for average human height gains over the last 150 years , the nation that stands out most is the Netherlands . Today , the average height of adult Dutch men is around 184 cm and 170cm for women . They are a whopping 19 cm taller than their counterparts in the mid-nineteenth century .
