"Implementing a research programme with the German Embassy against gender based sex selection in Delhi's eleven districts from February, it came to light the situation is becoming even worse," said Centre for Social Research (CSR) director Ranjana Kumari.
"Some sections of the media reported the child sex ratio of 789 girls per 1000 boys in the last quarter," she said.
As per the 2011 census, Delhi has recorded a low child sex ratio of 866 girls to 1000 boys.
"There has been an increase in female foeticide in the country due to easy access to technology these days," said Rashmi Singh, director, National Mission for Empowerment of Women.
"The problem has now become much more widespread and we are witnessing skewed sex ratio even in rural areas," she added.
According to the recent UNICEF report, India has lost over one crore girls since 2007 and there is a dramatic decline in the sex-ratio.
