Question 1

[Rob L]

What is the UK adult average height for male and female and how has this changed over the last 50 years

[mikewith]

According to earlier answers the average height of women is 5 ft 4 inches... question 8778 and for men it's 5 ft 9 inches: question 7381

Not sure of how that's changed over the last 50 years but humankind is getting taller, thanks largely to improved nutrition.
