Sex ratio in a population is defined as the number of females for every thousand males.
This metric is used to understand the balance between the male and female population in a given area or group.
In India, the sex ratio is typically calculated as the number of females per 1000 males. A ratio of 1000 indicates an equal number of males and females; a ratio below 1000 indicates fewer females than males, and vice versa.
