Wittgenstein Centre Human Capital Data Explorer (WIC) education-specific lifetables for five SSP base scenarios, 2020-2100

Given the education-specific five-year survival ratios in the Wittgenstein Centre Human Capital Data Explorer (WIC) projection outputs, a method was developed to generate education-specific lifetables. This dataset contains the resulting country-level lifetables for five SSP base scenarios: SSP1, SSP2, SSP3, SSP4, and SSP5. The release covers 200 countries for each scenario and provides one RDS file per country-scenario pair. The lifetables preserve the original education-specific survival ratios (`sx`) as the canonical projection object. A conventional life-table view is provided through variables such as `lx`, `dx`, `qx`, `Lx`, `Tx`, and `ex`, with a companion `sx_ladder_ex` diagnostic for old-age interpretation. The release also includes audit fields identifying rows where the conventional closed-table layer was repaired to satisfy closed-interval consistency while preserving the underlying `sx`/`Lx` ladder. The package includes metadata tables, country and scenario identifiers, a file manifest with SHA-256 checksums, a variable dictionary, a recode dictionary, methods and repair notes, and simple R/Python examples for reading the files.
