What is the average height for an adult?

The Centers for Disease Control and Prevention identifies the average height for American women as about 5 feet, 4 inches tall. The average man is just over 5 feet, 9 inches tall.

According to National Public Radio, the average heights for both men and women vary around the world. When the United States first became a country, it had the tallest population, but by 2010, northern Europeans were significantly taller. For instance, the average adult male in the Netherlands is 6 feet tall. Heights tend to reflect the health and nutrition levels within a country, and these are often linked to a nation's economy.
