The world's least livable cities 2021
1. Damascus, Syria
2. Lagos, Nigeria
3. Port Moresby, Papua New Guinea
4. Dhaka, Bangladesh
5. Algiers, Algeria
6. Tripoli, Libya
7. Karachi, Pakistan
8. Harare, Zimbabwe
9. Douala, Cameroon
10. Caracas, Venezuela

But while there have been many significant differences towards the top, very little has changed at the bottom of the list.
While Damascus sits in last place once again "as the effects of the civil war in Syria continue to take their toll," it's closely followed by Nigeria's Lagos, Papua New Guinea's Port Moresby and Bangladesh's Dhaka, which were all in either similar or identical spots in 2019.
These cities have consistently performed badly over the years due to the instability caused by ongoing civil unrest and military conflicts, amongst other issues.
According to the report, conditions here have deteriorated even further in the past 12 months, especially when it comes to healthcare, due to Covid-19.

[s]I really can't argue about the stress, Lagos can really be stressful place to live, but that it comes second at the least place to live I seriously don't agree. Even in Nigeria Ph is not a better place to live than Lagos, owing to the level of street violence and air pollution.[/s]

Some people are worried that Biafra would not be a good country, they are not worried that their most important city constantly tops the list of shithole cities every year.

Say what you want to say about Biafra but know this, Enugu the capital of Biafra would never be on this list.

Douala Cameroon is not as beautiful as Enugu, so Enugu is still a city but will never be one of the cities on this list, just like Accra or Cotonou never makes it to the list

When we ignore arguments about Lagos and Enugu, Onitsha or Aba, we know what we are doing.
Only monkeys and savages live in Lagos. The type that brag about how many hours they spent in traffic or how hot their hood is based on how many slaps they received from one hungry agbero
