Since the 1940s, the US has been adding roughly 9 million new homeowning households about every 10 years. This, after all, is a fundamental component of the American Dream. But Aziz Sunderji -- who writes over at Home Economics -- has recently been arguing that this 80-year boom is now at an inflection point. And it is largely because the rate of population growth in the US is now declining. Here's his chart, which uses data from the US Census Bureau and the World Bank:

In fact, for the first time ever, the Census Bureau is now forecasting the US population to start declining. The current forecast has its population reaching a high of 370 million in 2080 and then declining to 366 million by 2100. But even before these far off dates, organic growth is expected to turn negative in less than 15 years (see above). So yeah, it makes sense that this would impact the real estate sector.
