Crowdedness in Imest's Settlement Domes

To keep safe from anything Imest's unpredictable oceans has to offer to land life, the planet's most major cities, or at least the planet's richest settlements, have decided to keep themselves safe by building a protective dome over them. Obviously, a city's dome can only hold up to a certain limit of its own weight, so the people try not to build it too big, otherwise the entire city built underneath it would be crushed. 

Because of that, major cities are much smaller in area compared to the major cities in Imest's neighbours, however they are but significantly more crowded. Expect to see slums and homelessness among the large buildings. 

Poorer cities and towns are significantly more at risk to Imest's natural dangers since they haven't enough money to start a dome project. The people living in unprotected settlements have no protection from the ocean's natural disasters like tsunamis and the dangerous beasts of the wilderness.
