Sorry, which density advocacy groups have this nice idea as their literal goal?

Density is the population of a metropolitan area divided by its total area. Not population divided by the footprint area of residential lots. Density advocacy is all about accommodating population influx; it is really burgeoning population advocacy.

Every group I know of that actually advocates for density does have this as their goal. It is a bit odd that the external reputation is that they do not, to the point that parallel orgs sometimes appear advocating for pretty much the same things but "with more emphasis on livability" or similar.

Really? Is this documented somewhere? What is the typical proposal for how they plan to keep the population constant, after creating all that space? I've not heard of this. It's always about how many more millions of people could live here if we rearranged things.

I've never heard of a density advocacy group being opposed to population growth. Density advocacy is practically synonymous with at least acceptance (if not advocacy) of urban population growth. Population growth is in fact like a sacred cow. You must never blame any urban problems on population growth; the cause is always not enough vertical build.

Is there any example of a density anywhere going on record that the metropolis in this local neck of the woods should somehow say no to more people, rather than building more?

Have other metropolitan areas do the same so there is no net migration.

There is a difference between refusing new people and having population growth as a goal. People exist, they have to live somewhere, increasing density increases the housing stock and gives them somewhere to live.

If one city is hostile to giving them somewhere to live and another isn't, people might move from the hostile place to the amiable place. But the solution to this is obviously to make the other city less hostile, not to make sure that all cities are maximally hostile.
