Workforce decline is essentially baked in by current cohort data — the population “already born or not” means the next two decades' labor force is mostly determined. UN WPP's three fertility variants frame the plausible range: medium-fertility settles near 750M by 2050; low-fertility nearer 700M; forced-restructure scenarios reach 650M. The interesting question isn't whether — it's where the curve bends between 2033 and 2037, when policy response either lands or doesn't.
These are not our predictions. UN WPP publishes these scenario variants; we visualise them and connect them to OpenWatch's signal stream.
