I Built a Model to Find the World's Best Tennis Nation

Описание: Which country is actually the best at tennis?

This video is a deep dive into the countries that have defined modern tennis - Spain, United Stats, Serbia, Italy, Australia, Switzerland and more. And it crowns a winner using a transparent, weighted scoring model.

Spain feels like the obvious answer at first. Rafael Nadal's 22 Grand Slam titles, Carlos Alcaraz rising to world number one at a historic pace, and a clay-court culture that consistently produces elite competitors all point in that direction. But when you zoom out, the picture gets more complicated. The United States has been elite across both the ATP and WTA tours for decades, Serbia's case is anchored almost entirely by Novak Djokovic's record-breaking dominance, Switzerland produced Roger Federer and Stan Wawrinka, and right now Italy may be the deepest country in men's tennis thanks to Jannik Sinner and the players coming through behind him.

To make sense of that, each country is evaluated across two dimensions. The first is legacy, which accounts for sixty percent of the total score and measures who actually won the biggest trophies over time. This includes Grand Slam singles titles, weeks spent at world number one, year-end number one finishes, Masters 1000 titles, and sustained top ten presence across seasons. These are the currencies of dominance that define eras, whether that's Djokovic, Federer, Nadal, or the American run of players from Connors and McEnroe through Sampras and Agassi.

The second dimension is the factory score, which makes up the remaining forty percent and focuses on repeatability rather than peak. This looks at how many distinct top ten players a country has produced since 1980, how many players they currently have inside the top one hundred, and whether their success is concentrated in one outlier. If one player accounts for most of a country's success, we apply a deductive concentration penalty of up to minus ten points. Because producing Novak Djokovic or Roger Federer once is incredible - but it isn't the same as producing waves of elite players across generations.

Each category is normalised so the strongest country in that metric receives the full weight allocated to it, and every other country receives a proportional share based on how close they are to the leader.

Final Results:
1. United States - 90 points
Finished first overall due to unmatched longevity across multiple eras, dominance on both ATP and WTA tours, zero concentration penalty, and the highest combined legacy score once men's and women's tennis are included.

2. Spain - 88 points
Finishes a close second overall and ranks first as the best tennis player factory combining elite peak success with Rafael Nadal and Carlos Alcaraz alongside a repeatable development system that consistently produces top players across generations.

3. Italy - 74 points
Scores highly due to modern depth and current top-100 representation, making it the strongest active pipeline in tennis right now, but lacks the historically legacy volume to challenge the top two

4. Serbia - 70 points
Records one of the highest legacy scores thanks to Novak Djokovic's dominance, but finishes lower overall due to an extreme concentration penalty reflecting reliance on a single generational outlier

5. Australia - 70 points
Matches Serbia's total through strong depth, sustained relevance across eras, and minimal concentration, while also standing out as the most overpowered nation on a per-capita basis
