In Census 2011, in comparison to that in Census 2001 the highest decrease in sex ratio of 0-6 age group was in :

Question

Accepted Answer

The correct answer is Jammu and Kashmir because the 2011 Census data reveals that it experienced the most significant decrease in the sex ratio (number of females per 1000 males) in the 0-6 age group compared to the 2001 Census. While other states also saw a decline in this ratio, the magnitude of the decrease was highest in Jammu and Kashmir. This decline could be attributed to various factors such as son preference, access to and use of sex-selective abortion technologies, and potentially underreporting of female births in the 0-6 age group.

Here's why the other options are incorrect:

*   **Haryana:** While Haryana is known for its historically low sex ratio and efforts to improve it, the *decrease* in the 0-6 age group sex ratio between 2001 and 2011 was not as high as that observed in Jammu and Kashmir. Haryana's situation is serious, but the *change* was less drastic.

*   **Punjab:** Punjab also faces challenges related to sex ratio imbalances. However, similar to Haryana, the *decrease* in the 0-6 age group sex ratio between the two census periods was not as pronounced as in Jammu and Kashmir.

*   **Gujarat:** Gujarat also experienced a decline in the 0-6 age group sex ratio, but the *magnitude* of this decline was less than that observed in Jammu and Kashmir. Therefore, it is not the correct answer.

In summary, while all the listed states faced challenges related to the sex ratio of the 0-6 age group, the 2011 Census data indicates that Jammu and Kashmir experienced the largest *decrease* in this ratio compared to the 2001 Census, making it the correct answer.
