Lagos is the eighth most dangerous megacity for women to live in, according to a Thompson Reuters survey. Cairo, capital of Egypt, was rated the world’s most dangerous megacity for women while London, the best.

The poll which sought the opinion from some 380 experts in women’s issues, was conducted in 19 of the world’s biggest megacities (as ranked by the United Nations) between June and July 2017.

The cities were ranked based on four major factors – sexual violence, access to healthcare, cultural practices and economic opportunities. Karachi in Pakistan followed Cairo, and next in line was Kinshasa in Democratic Republic of the Congo, then the Indian capital New Delhi.

Women’s rights campaigners in Cairo said traditions dating back centuries made it a tough city, with discrimination rife. Delhi and Sao Paulo emerged as the worst cities when respondents were asked if women could live there without the risk of sexual violence, including rape, attacks or harassment.
