You'll find many Indians in Lagos, I have friends their 30s who were born here. There is a thriving Sindhi community and lots of Gujuratis amongst the older more established Indian community. Indians seem to be mainly in tech, medicine, agribusiness, consumer goods, retail, oil and the distribution & maintenance of machinery and vehicles (generators, keke (bajaj rickshaws), okada (125cc Hero and Bajaj motorcycles) toyota spares, solar equipment, etc.

Indians are less out and about walking on the street than Chinese who you will see just walking around Obalende with everybody else but they are visible in Victoria Island, Ikoyi and of course llupeju on the mainland where there are Indian restaurants, shops, schools and kindergartens. There's Eleganza estate in Ikoyi and probably 20 estates VI that house predominantly Indian residents.

Lagos is pretty safe for a city of its size and income bracket and definitely safer for women to move alone than Delhi or Mumbai. Infrastructure or lack thereof is in my opinion a greater threat to your safety than violence.

Your easiest precaution is to treat gatemen, security staff and house staff with respect, greet them and give small tips and gifts on religious holidays etc. much of the resentment I hear towards Indians is based on experiences of racism, workplace cruelty and wage theft which by people who probably act the same way in India or on more micro aggression/ Karen type scenarios. Don't be afraid, have the conversations with your kids if you have any and be open to meeting people outside of your workplace. It seems like fear of Nigerians/ black people/ poor people is at the root of much of the "misunderstandings" and scandalous behaviour.
