Hint: A Census is a process of systematically enumerating, gathering, and recording the details of all the members of a given population. It is generally associated with the population of a country or housing census.
Complete step-by-step solution:
The United Nations defines the important features of these censuses as individual enumeration, universality with a different territory simultaneity, and with a d defined periodicity. In India census is recorded after every 10 years.
Sex ratio can be defined as the total number of females present for every 1000 males. It is a valuable source to determine the population of women in any given region. According to the population census of 2011, India has only 940 females per 1000 males. Even though the sex ratio shows an upward trend from the Census of 2001 data yet it is not very satisfactory.
Kerala has the highest sex ratio in India with 1084 females for every 1000 males. Puducherry stands second in the list with 1037 females for every 1000 males. Daman and Diu have the lowest sex ratio with only 618 females per 1000 males.
Arunachal Pradesh has the distinction of having the highest child sex ratio of 972 female every 1000 male children. The lowest child sex ratio recorded in India is of Haryana with only 834 female children for every 1000 male children.
Thus, option (A) is correct.
Note: To determine the child sex ratios only children under the age of 6 are taken into account. Most states in India have a poor child sex ratio due to social evils like female foeticide. The Government of India has taken many steps to uplift the sex ratio in India.
