Brazil vs Mexico, explained
Today Brazil is the larger of the two, with about 213 million people against Mexico's 132 million. Brazil is the world's 7th most populous country and Mexico the 11th.
Their paths to 2100 differ. Brazil falls sharply over the century, moving from about 212 million to 164 million (-22.5%). Mexico stays broadly flat, going from 130 million to 131 million (+0.2%).
The order does not flip this century: Brazil is still the larger of the two in 2100. The two trajectories run in parallel rather than crossing.
The deeper contrast is age and fertility. Brazil has a median age near 34 and 1.61 births per woman, against Mexico's 29 and 1.89. All figures follow the UN's medium-variant projection.
