While it's true that Japan and Italy are the only two major developed countries suffering actual decline, basically all of the big wealthy countries are experiencing fertility below replacement.
You are shifting goals, from the population growth to the fertility rate. Indeed some countries more that others are growing because of the migration and not fertility. Also that's not a new phenomena at all.
All that doesn't negate the fact of the population growth.
As a consequence of that growth we need more housing, and that's not happening in a needed rate.
That's absolutely not true. Otherwise cite reputable statistic sources. I'm looking at https://www.cia.gov/the-world-factbook/field/population-grow...
