Note: Housing economist Tom Lawler was been way ahead on this, see for example: Lawler: Updated “Demographic” Outlook Using Recent Population Estimates by Age, Lawler: “Off-Calendar” Census Population Projection Update Coming; To Include Alternative Migration Scenarios, Lawler: US Population Growth Slowed Again in 2019.
From the Census Bureau: A Changing Nation: Population Projections Under Alternative Immigration Scenarios
Higher international immigration over the next four decades would produce a faster growing, more diverse, and younger population for the United States. In contrast, an absence of migration into the country over this same period would result in a U.S. population that is smaller than the present. Different levels of immigration between now and 2060 could change the projection of the population in that year by as much as 127 million people, with estimates ranging anywhere from 320 to 447 million U.S. residents.Click on graph for larger image.
The 2017 National Projections main series, released in September 2018, present one scenario for the future population. These projections will only hold true if the assumptions about births, deaths, and migration match the actual trends in these components of population change. International migration is difficult to project because political and economic conditions are nearly impossible to anticipate, yet factor heavily into migration movements into and out of a country. While we do not attempt to predict future policy or economic cycles, we do recognize the uncertainty surrounding migration and the impact that different migration outcomes could have on the future population. To account for this, we have produced three alternate sets of projections that use the same methodology and assumptions for fertility, mortality, and emigration, but differ in the levels of immigration that they assume: high, low, and zero immigration. This report compares the results from the three alternative scenarios of projections and the main series, focusing on differences in the pace at which the U.S. population grows, diversifies, and ages.

Based on Lawler's recent analysis of births, deaths, and immigration, these projections are probably optimistic.
Depending on the which scenario happens, this could have a significant impact on the US economy and especially housing - and is a key reason the future is not as bright as it was a few years ago.
