Damascus and Aleppo are both more than 1 million people, Astana and Almaty and Astana are both over 1 million people, and Mashhad and Tehran are both over 1 million people.
Even within city limits, Chittagong has a population of 2.5 million (metropolitan population over 4 million). Basra and Isfahan also have over 1 million in every source I've seen.
The source I used didn't include any of these. I double checked and everything still seemed right. I'm not ignoring it, I'm just not changing because I'm keeping with my source
city proper is inferior to urban area count as different countries govern cities in different ways. For example city proper separates Shenzhen Hong Kong and Guangzhou despite them clearly being the same city.
