(http://www.wisegeek.com/which-country-has-the-tallest-people.htm) The tallest people, on average, are the Dutch and most citizens of the Netherlands are caucasian. Statistically, the tallest people in the world, as measured by country are the Dutch. The average height for all adults for the Netherlands is 6 feet 1 inch (1.85 m). This great leap in height is a huge change for Holland, where about 100 years ago, 25% of men who attempted to join the army were rejected as being too short, less than 62 inches (1.57 m) tall. There are taller people belonging to certain populations within countries. This is especially true of the Maasai people, who live in parts of Tanzania and Kenya. But as a whole, the citizens living in the Netherlands are on average, the tallest people. Even people who have immigrated to the Netherlands from other parts of the world are taller on average than their racial groups in their countries of origin. Standing next to the Dutch, almost shoulder to shoulder, are the Danes. Average height in Denmark is 6 feet (1.83 m). Americans, who once were the tallest people, have fallen in stature and are on average about 5 feet, 10 inches (1.78 m). Researchers have attempted to account for what makes a certain country have the tallest people and conclude that factors for height include a combination of genetics and nutrition. The Dutch, several hundred years ago, were some of the tallest people in the world. Uneven distribution of wealth, poor nutrition, and years of bad crops certainly contributed to keeping the Dutch shorter for many years. From a genetic standpoint, though, the Dutch could have been the tallest people sooner with appropriate nutrition, especially during early childhood years.

What are the choices? Please define "race" and where exactly to draw the lines between them.

The Dutch!

The tallest people in the world belong to the Nilotic tribes of Southern Sudan, Kenya, and Tanzania. One of the largest NBA players ever, Manute Bol, is from the Dinka people in Sudan. A short quote from an article by Stefan Antei: "Today, this African race in its more or less pure form lives mainly in the southern Sudan and surrounding areas, while in central/western Africa they are heavily mixed with Congo type (the common typical Black Africans, like Bantu tribes). In Ethiopia and Somalia, this race mixed intensively with a White one coming from southwestern Asia thousands of years ago. In the case of some Sudanese tribes, males can have an average height of 1.9 m (6 ft, 4in) (!), while women of 1.8 m (6 ft) (!). These people have slim but strong bodies, and their heads are more elongated than in the case of the typical African Blacks. In case of a mixed race, these huge heights may not be generally attained by the population. The most famous group and more racially preserved of the Sudanese race are the Nilotic tribes (they all originated on the Upper Nile area). The most famous are Maasai, Turkana, Samburu and Dinka, whose main occupation is animal husbandry."

In Europe, there are certain regions in Serbia and Montenegro with an unusual number of very large people, but these do not suffice to make all Serbians bigger on average than the Dutch.

Blacks. Have you watched basketball lately?

the sudanese hands down, are the tallest people in the world.i believe that people must be leaning toward the dutch because they are a country but the sudanese are from a geographic are of africa. if the question is "what country have the tallest people?", you get away with the dutch answer but if the question is, " who are the tallest people?", the answer has to be the sudanese

I would guess Africans. Besides that I've seen pictures of ancient humans being dug up measuring to be over 30 feet tall!

The giants.
