US demographic turning point

The United States is approaching a major demographic turning point. For most of the 20th century and into the early 2000s, births consistently far outpaced deaths,in 2007, the natural increase stood at about 1.9 million per year. That figure has now plummeted to roughly 519,000, signaling a profound shift in population dynamics driven by long-term changes in fertility, mortality, and migration.
