France received more international tourists than any other country in 2024 — approximately 102 million arrivals, making it the first country in history to surpass the 100 million annual mark. Spain ranked second with 93.8 million, the United States third with 72.4 million. Turkey and Italy round out the top five. But raw arrival numbers obscure important distinctions: the United States earns more tourism revenue than any other country despite ranking third in arrivals. This ranking covers the top 20 countries by international tourist arrivals using UN Tourism (UNWTO) 2024 data, with methodology, historical context, and revenue analysis.

China has the world's largest military by active personnel — approximately 2,035,000 active-duty service members as of 2024, according to IISS Military Balance estimates. India ranks second at roughly 1,476,000, the United States third at approximately 1,316,000. North Korea and Russia complete the top five. But personnel count is only one dimension of military capability: the United States spends more on defense than the next ten countries combined, and technology, doctrine, and logistics matter as much as headcount. This ranking covers the top 20 countries by active military personnel using IISS Military Balance 2024 and SIPRI data, with methodology, spending comparison, and caveats.
