Recent CDC data confirming a sub-1% drop to 3.61 million U.S. births in 2025, alongside a record-low general fertility rate of 53.2, has anchored trader consensus around the 3.53M–3.59M bands. Steep declines among women in their teens and twenties—driven by shifting cultural priorities, economic pressures, and career timelines—offset modest gains for those in their thirties and forties, sustaining the downward momentum. With roughly 49% of 2026 births already recorded, the close split between the two leading ranges reflects uncertainty over whether the pace of decline will hold or moderate slightly before year-end. Historical patterns of gradual fertility erosion and the absence of major policy reversals keep these mid-range outcomes as the clear frontrunners.
