Dhaka is still be kind of a mess now in 2022. It will probably take around the mid-2030s when all the large infrastructure projects are completed and most of the slums are cleared for it to look like a modern metropolis on the same level as cities like Jakarta are now.
@Indos : Are you able to advise on how the slum clearance is going on in Jakarta right now?
People cannot live in illegal land anymore here, in the past they use land near the river, but actually I have been living in Jakarta for quite long and never see that slum footage posted by foreign media from India, Singapore, Australia about Jakarta. There is Indonesian said in the comment section of CNA youtube channel that the footage comes from different region in Indonesia.
The high density region in Jakarta is in North Jakarta. Many are fishermen who live near the coast whose houses always been captured by foreign media if talking about "sinking " Jakarta.
North Jakarta. Actually they are not slum, but small houses. For some years I had worked in this area near Jakarta coast ( near Tanjung Priok port ). High density but not all houses are small either. I think we can only improve the area by improving Jakarta people living standard. It will take some time.
North Jakarta ( surprisingly this is also where Chinese Indonesian like to live, they like to live near the coast areas since it is good based on Fengshui )
Just compare with South Jakarta where I live ( more green )
East Jakarta is pretty decent as well but still quite dense
Many Jakarta young couple move to Jakarta satellite cities but working in Jakarta.
For example is BSD Serpong where my older brother also live in here. There is train route between Serpong and Jakarta and also high way ( toll road ).
For North Jakarta, Jakarta governor start making affordable apartment there, but this is not massive thing. I can say the only way to improve the living condition in Jakarta is through economy and also government intervention like increasing the minimum wage. It needs gradual process
