The world population is a diverse mix of ethnicities and cultures. According to the CIA World Factbook, there are over 7000 ethnic groups in the world. However, the distribution of these ethnic groups is not uniform across the world.
The Kaiser Family Foundation provides a comprehensive report on the population distribution by race/ethnicity in the United States. According to their report, the largest ethnic group in the United States is White, comprising 60% of the population, followed by Hispanic/Latino (18%), Black (12%), Asian (6%), and other races (4%).
On a global scale, the Infogram website provides an interactive pie chart that shows the racial composition of the world population. According to the chart, the largest ethnic group in the world is Han Chinese, comprising 18.1% of the world population, followed by South Asians (16.3%), Europeans (9.6%), Sub-Saharan Africans (9.4%), Arabs (5.2%), and other ethnic groups (41.4%).
It is important to note that the racial composition of the world population is constantly changing due to various factors such as migration, birth rates, and mortality rates. Therefore, the data presented here may not be up-to-date.
