What is the proportion of whites, yellows and blacks in the world?

Yellow race, big black race, big black race, big white race! Huang and the other two! The specific ratio is as follows!

Caucasians, also known as Eurasian or Caucasians, are the most populous race in the world, accounting for about 54% of the world's total population.

The yellow race, also known as Asian Americans, is the second largest race in the world, accounting for about 37% of the global population.

Black people are the third largest race in the world, accounting for 8.5% of the world's total population.

1, yellow race: yellow (brown) skin, brown eyes, straight black hair, medium nose height, medium lips, medium build, located in central Africa and southern Asia;

2. Caucasian: fair skin, light brown, gray and light blue eyes, golden wavy hair, thin nose, thin lips, tall figure, located in southern Oceania and Europe;

3. Black race: dark brown skin, black (brown) eyes, short curly hair, low and wide nose (flat), thick lips and long limbs, located on the south bank of the Arctic Ocean.

The more pigment cells in the skin, the darker the skin color. From the geographical distribution, from the equator to the polar regions, the skin color of all ethnic groups gradually becomes lighter. In the equatorial region, strong solar radiation and the increase of pigment in the skin protect people from ultraviolet rays.

People between high latitude and low latitude have yellow skin.

The difference in appearance of each race is the result of adapting to the environment. It cannot be said that people of different colors are noble, people of different colors are inferior, and all people should be equal.

July this year 1 1 is the15th World Population Day. After World War II, the world population entered a stage of rapid growth, and this rapid growth trend continues to this day. The explosive growth of population has brought great pressure to the resources and environment of the earth. Over the years, many governments have made strenuous efforts to control population growth. The following are some of the latest world population figures extracted from the report of the United Nations Population Division.

The world population has tripled in 70 years: 1930 is about 2 billion, 1960 is about 3 billion, 1974 is about 4 billion, 1987 is about 5 billion, and 1999 is about 6 billion. At present, the world population is about 6.4 billion. If family planning measures are effectively implemented, the world population is expected to be controlled at around 8.9 billion in 2050. The five largest countries in the world: China (65.438+0.3 billion), India (65.438+0 billion), the United States (297 million), Indonesia (223 million) and Brazil (65.438+0.8/kloc-0.0 billion).

At present, the annual growth rate of the world population is 1.2%, among which the least developed countries have the highest annual growth rate of 2.4%. The annual population growth rates of developed countries and underdeveloped countries are 0.25% and 1.46% respectively.

At present, the world's population has a net increase of 77 million per year, with an increase of 2 to 3 people per second. The seven countries that "contributed" the most to the annual growth of the world population are: India (2 1%), China (13%), Pakistan, Nigeria, Bangladesh, Indonesia and the United States (all 4%).

The population rankings of major regions in the world are: Asia (3.87 billion), Africa (869 million), Europe (726 million), Latin America and the Caribbean (550 million), North America (329 million) and Oceania (33 million). Among them, Africa has the fastest population growth, with an annual growth rate of 2.3%. The population of Europe has been decreasing in the past 10 years, with an average annual negative growth of 0.02%.

The population of China accounts for 20% of the world population.
