Write short note on :Sex ratio.

1.	Write short note on :Sex ratio.
Answer» 1. The number of females per thousand males is called sex ratio. 2. The sex ratio is calculated with the help of the following formula : Sex ratio = \(\cfrac{Total\,number\,of\,females}{Total\,number\,of\,males}\) x 1000 3. If the number of females per thousand males is less, the sex ratio is considered to be low. On the other hand, if the number of females per thousand males is more, the sex ratio is considered to be high. 4. According to Census 2011, the sex ratio was highest (1084) in the state of Kerala. According to Census 2011, the sex ratio was 929 in the state of Maharashtra. 5. Out-migration of males leads to high sex ratio in a region from where males have out-migrated. Less female birth rate leads to low sex ratio.

1. The number of females per thousand males is called sex ratio.

2. The sex ratio is calculated with the help of the following formula :

Sex ratio = \(\cfrac{Total\,number\,of\,females}{Total\,number\,of\,males}\) x 1000

3. If the number of females per thousand males is less, the sex ratio is considered to be low. On the other hand, if the number of females per thousand males is more, the sex ratio is considered to be high.

4. According to Census 2011, the sex ratio was highest (1084) in the state of Kerala. According to Census 2011, the sex ratio was 929 in the state of Maharashtra.

5. Out-migration of males leads to high sex ratio in a region from where males have out-migrated. Less female birth rate leads to low sex ratio.
