About This Statistic

OECD Green Growth measure 'Natural science instruction time in primary education'. The map uses the exact official 2025 slice in Hours per year; fixed dimensions: FREQ=A (Annual); ACTIVITY=_T (Total - all activities); PRICE_BASE=_Z (Not applicable); TIMELINESS=1 (1 year lag, timely).

MapTheory uses only finite ISO-mapped observations from the fixed 2025 OECD slice recorded below. Aggregates, missing values, non-ISO geographies, conflicting duplicate observations, and every other year or dimension slice are excluded; MapTheory never imputes or interpolates missing countries.
