The average female height varies based on a variety of factors such as heredity, hormones, diet, and where she was born and raised. The average height for a 20-year-old American woman is presently 5 feet 4 inches (162.56 cm). While the average height for an American guy is 5 feet 9 inches (175.26 cm) around the same age.
American women were the fourth tallest in the world a century ago, towering at 159 cm (5 feet 3 inches). With an average height of 163.5 cm, they are currently the 42nd tallest in the world (5 feet 4 inches). While Americans’ heights did not grow significantly, their Body Mass Index did.
According to the authors of the 2016 survey, decreased growth in height among Americans may be attributed to poor nutrition. They also identified immigration from nations with individuals who are normally shorter in stature, as well as worse quality obstetric and pediatric healthcare, as potential contributors.
According to several unverified sources, the global average height for women is 5 feet 3 inches or one inch taller.
Some global height trends for women aged 18–40:-
Genes, or your DNA, have a significant role in your height. Scientists believe that your DNA is responsible for 80 percent of your height. A recent study has shown approximately 700 ways in which genes impact your height.
Your living circumstances, on the other hand, play a role. Childhood malnutrition and disease, which researchers relate to living standards, can stifle growth. As a result, the average height of a country’s population may reveal a lot about the country’s quality of life.
Significant location-based factors such as water sanitation, nutrition, availability of vaccines, and access to adequate healthcare, all have an impact on an individual’s height.
