I agree Sumon. Our challenge is to increase the economic density in Dhaka and Chittagong while decreasing their population densities. This is easier said than done. Increased economic density makes it more difficult to decrease population density. Expectations of higher incomes and better living conditions rise with rise in economic density. The answer therefore lies in balanced growth in the peripheries of our two major cities so as to make those places livable for young and old. How do you get such balanced growth? We will have to invest in infrastructure, institutions and innovations to substantially improve service delivery in the peripheries.
