Human Height and Weight are mostly hereditable, but lifestyles, diet, health and environmental factors also play a role in determining individual's physical characteristics. The dataset below contains 25,000 records of human heights (in inches) and weights (in pounds). These data were obtained in 1993 by a Growth Survey of 25,000 children from birth to 18 years of age recruited from Maternal and Child Health Centres (MCHC) and schools and were used to develop Hong Kong's current growth charts for weight, height, weight-for-age, weight-for-height and body mass index (BMI).
