Long-Run SSP Population and Human-Capital Projections, 2025-Rebased, 2100-2300 (zen2300y2025V01)

This dataset (version zen2300y2025V01) extends the 2025-rebased SSP population and human-capital projections beyond the conventional 2100 horizon to the year 2300. It is the long-run continuation of the 2025-2100 release (doi 10.5281/zenodo.21738149) and covers four Shared Socioeconomic Pathways: SSP1, SSP2, SSP3, and SSP5. Results are disaggregated by region, sex, five-year age group, and six levels of educational attainment, at five-year intervals, for 200 countries and territories together with UN area, subregion, and world aggregates. Files are gzip-compressed CSV and can be read without unpacking. Each scenario is provided as a separate file. The dataset also includes a recode dictionary, a file overview, and a README describing structure and caveats. No SSP4 extension. The long-run extension was produced for SSP1, SSP2, SSP3, and SSP5 only. Analyses requiring SSP4 must stop at 2100.
