Values use UN SDG series EN_WBE_INWTL, release 2026.Q2.G.01, one fixed 2025 reference year, unit Square kilometers, and the fixed selection Reporting Type: Global. Aggregates, missing/non-finite values, other dimensions, other attributes, and non-ISO geographies are excluded; MapTheory does not impute missing countries.

Methodology

UN SDG series EN_WBE_INWTL; year 2025; unit KMSQ; dimensions {"Reporting Type": "G"}; attributes {"Nature": "C", "Units": "KMSQ"} Official UN SDG metadata for indicator 6.6.1.
