Question

How is sex ratio determined?

Hint:

Recall the standard Indian demographic formula: females per 1000 males.

Answer 1

Step 1: Understanding the Concept:
Sex ratio is a demographic indicator showing the balance between males and females in a population.

Step 2: The Formula (India's convention):
\[ \text{Sex Ratio} = \dfrac{\text{Number of Females}}{\text{Number of Males}} \times 1000 \] It is expressed as the number of females per 1000 males.

Step 3: Interpretation:
A sex ratio of 940, for example, means there are 940 females for every 1000 males in that population. (Note: the international convention instead expresses males per 1000/100 females — India uses the females-per-1000-males form.)

Step 4: Final Answer:
Sex ratio is determined by dividing the number of females by the number of males in a population and multiplying by 1000, giving the number of females per 1000 males.
