A lighthearted analysis explores whether the entire global population of 8.3 billion people could theoretically fit inside the state of South Dakota, which has a current population of just 930,000 spread across 77,123 square miles. The article concludes that while the math shows it is possible, the author argues that South Dakota's unique rural character and charm should be preserved.

Why it matters

This story provides a whimsical thought experiment that highlights the sheer size and low population density of South Dakota, a state known for its wide open spaces and natural beauty. It touches on themes of urban density, population growth, and the value of preserving a state's distinct regional identity.

The details

Giving each person 4 square feet of space, the total space required for the world's 8.3 billion people would be 33.2 billion square feet. South Dakota itself has over 2 trillion square feet of land area, so theoretically the entire global population could fit inside the state's borders. However, the author notes this would require packing the population primarily into the less arable western part of the state, turning it into a dense urban landscape of skyscrapers "as far as the eye can see." The author argues that such a scenario would destroy the state's quiet rural character and charm.

• The current global population is approximately 8.3 billion people.
• South Dakota's current population is around 930,000 as of 2026.
