International school diversity — measured by student nationality mix — is highly concentrated: the most diverse schools globally cluster in fewer than 30 cities, despite 4,149 institutions spanning 300+ locations across 78 countries

Ranked by median number of student nationalities per school. Cities need at least 3 schools with nationality data to appear in the ranking.
| # | City | Schools | Median | Max | Diversity |
|---|
Median = typical school in the city. Max = most diverse school in the city. Diversity = WhereNext score (0-100) blending relative city position and absolute nationality count.
Individual schools with the highest student nationality counts. These schools are the gold standard for globally mobile families — children meet peers from dozens of countries.
Countries ranked by median student nationality count across their international schools. Hubs with large expat populations dominate — Singapore, the UAE, Hong Kong, and Switzerland consistently host the most globally diverse student bodies.
| # | Country | Schools | Cities | Median | Max |

Student nationality counts come from school-published profiles, admissions materials, and the International Schools Database. Each school in the WhereNext directory carries a number_of_nationalities field where the data is available — currently 0 schools across 0 cities.
The diversity score (0-100) is computed by scripts/compute-school-analytics.ts using two signals: relative position within the school's city (80% weight) and absolute nationality count (20% weight, with bonuses at 25, 40, and 60 nationality thresholds). The ratio-based formula means a school in a small city with 30 nationalities can score higher than a school in a global hub with 50 — what matters is how diverse it is for its market.
Inclusion criteria for the city ranking: a city must have at least 3 schools reporting nationality data to appear. Smaller datasets are statistically unreliable.
Inclusion criteria for the country ranking: a country must have at least 5 schools reporting nationality data to appear, ensuring the median is meaningful.
What this measures: the breadth of student nationalities at a given school. What this does NOT measure: educational quality, English proficiency, social integration, or how welcoming the school is to a specific minority. A high diversity score is a good signal for globally-mobile families — kids meet peers from many countries — but it should be one input among several when picking a school.
Data freshness:nationality counts are updated whenever schools update their public profiles. WhereNext reverifies on a rolling basis. Always check the school's current prospectus before applying.
Diversity is one input. Curriculum match, true cost, hidden fees, admissions difficulty, and your family's budget all matter too. The School Fit Brief combines all of them into a personalized 11-section advisory report — $49.
