The sex ratio in Mizoram is 917 females per 1000 males. This is lower than the national average of 940 females per 1000 males. The sex ratio in Mizoram has been declining in recent years. In 2011, the sex ratio was 946 females per 1000 males. This decline is likely due to a number of factors, including female infanticide, sex-selective abortion, and migration.
