India vs United States, explained
Today India is the larger of the two, with about 1.47 billion people against United States's 348 million. India is the world's 1st most populous country and United States the 3rd.
Their paths to 2100 differ. India edges higher over the century, moving from about 1.44 billion to 1.51 billion (+4.5%). United States keeps growing, going from 344 million to 421 million (+22.2%).
The order does not flip this century: India 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. India has a median age near 28 and 1.96 births per woman, against United States's 38 and 1.62. All figures follow the UN's medium-variant projection.
