Due to overpopulation, there has been a mass housing shortage in various developing countries

That's a rather glib leap of logic.

The 'shortage' is often simply substandard and/or dangerous dwellings due to corruption, theft, lack of code/code enforcement, etc.

If your problem is overpopulation, then creating more housing to accommodate even more overpopulation is madness. It's the fish-grow-in-proportion-to-aquarium phenomenon. Surely birth control and a cultural shift away from breeding like minks takes priority?

"Surely birth control and a cultural shift away from breeding like minks takes priority?"

Only for people of northwestern European descent in the U.S.A., according to the social and political policies that we've been seeing for several decades. Apparently, some influential people have been assuming that a population with less ingenuity would be easier to control and less likely to rise to compete.
