However, rural areas fared comparatively well in improving the ratio than urban centres. "In rural areas of the state, it has increased by four points from 945 in 2001 to 949 in 2011; while in urban areas it remained at 880 in both the years," said the review citing the Census records.
According to the review, there was an increase in sex ratio in the north-south belt of Gujarat except in Mehsana and Surat districts while Saurashtra region showed marginal decrease, except in Surendranagar and Porbandar districts.
Citing Census 2011, the review stated that tribal district of Tapi is at the first position with a sex ratio of 1,007 followed by other tribal districts Dang (1,006) and Dahod (990), whereas Surat is at the last position with just 787 preceded by Ahmedabad with 904.
The review stated that migration from within and outside the state to urban areas was the key reason for the decline in sex ration there.
"Large migration from within and outside the state into economically vibrant, industrial urban areas is one of the main factors for low sex ratio in Surat and Ahmedabad," it added.
"Combined with large share of urban population in the state, it reflects in a lower sex ratio for Gujarat as compared to all India ratio," the review stated.
In contrast to negative growth in sex ratio for adults, Gujarat has recorded improvement in child sex ratio, which take into account children in the age group of 0-6 years, from 2001 to 2011.
This is the first time child sex ratio has shown an increasing trend since the formation of Gujarat.
While the Census 2011 suggested a decrease of eight points at national level, Gujarat registered a growth of seven points.
"National child sex ratio has fallen from 927 in 2001 to 919 in 2011. However, in Gujarat, the child sex ratio has increased from 883 in 2001 to 890 in 2011. For the first time in five decades, Gujarat has recorded an improvement in child sex ratio," it said.
