The loaded World-energy series currently spans 1965-2024. The 1965-to-present milestone segment is linear in time, while years before 1965 use inverse-log compression. Years before 1965 include reconstructed historical estimates; from 1965 onward, the source series is methodologically more modern and comparable. Values after the official 2024 anchor year are model estimates.
