Question

Define Sex Ratio.

Hint:

For Indian context, the definition is always 'females per 1000 males'. In some Western countries, it might be reversed ('males per 100 females'). Always stick to the definition prevalent in your region or as specified in the curriculum. The formula helps in remembering the exact definition.

Answer 1

Sex ratio is a demographic indicator that measures the balance between males and females in a population. It is typically defined as the number of females per 1000 males in a population. The formula is:
\[ \text{Sex Ratio} = \left( \frac{\text{Total number of females}}{\text{Total number of males}} \right) \times 1000 \] A sex ratio greater than 1000 indicates more females than males, while a ratio less than 1000 indicates a deficit of females. It is a crucial indicator of gender equality and social well-being in a society.
