Population Projections (2026-2050)
Near-zero growth suggests that United States is entering a period of demographic stability—or, depending on policy responses, the early stages of decline. Below-replacement fertility of 1.6 births per woman means natural growth alone cannot sustain the current population level indefinitely. As a United Nations member state, United States participates in global discussions on sustainable development that will shape its demographic future.
