Libertador General San Martín Population 2026

Important: These are model inputs, not a measured city age profile. Country-level birth, death and life-expectancy values are applied to the city baseline because city-level vital statistics are not available consistently for every location in this dataset.

The imported city population is the baseline observation used by this page. We do not present reconstructed historical city populations as observed facts because applying today's national birth/death rates backward would not account for migration, boundary changes or historical rate changes.

If current national birth and death rates stayed constant and migration were ignored, the model would produce 50,249 by 2030, 54,850 by 2040, and 59,872 by 2050. This is a scenario calculation, not an official forecast. It assumes constant rates and excludes migration, boundary changes, policy and economic shifts.
