Which one of the following statements regarding sex composition is not correct ?
- A.In some countries, sex ratio is expressed as number of males per thousand females.
- B.In India, sex ratio is expressed as number of females per thousand males.
- C.At world level, sex ratio is about 102 males per 100 females.
- D.In Asia, there is high sex ratio.
Correct answer
Explanation
The correct answer is D, In Asia, there is high sex ratio. Expressed as women per men, Asia has a low sex ratio, because several of its large countries have fewer women than men.
The sex ratio compares the number of women and men in a population. Many countries, and the world figures, express it as males per 100 or per 1000 females; by that measure the world has about 102 males for every 100 females. India uses the opposite form, females per 1000 males, and the 2011 Census recorded 943. The ratio is favourable to women in much of Europe and in countries with long life expectancy, while it is low in parts of Asia such as China, India, Pakistan and the Gulf countries, where son preference and male migrant workers tilt the balance.
A is wrong to choose because some countries do state the ratio as males per thousand females. B is wrong to choose because India does count females per thousand males. C is wrong to choose because the world ratio is about 102 males per 100 females.
Exam tip: India: females per 1000 males (943 in 2011); world: about 102 males per 100 females; Asia: low ratio.
