How many countries are there, and how is that decided?

There are 195 recognized countries in the world today [1, 2].

Determining this number is not as straightforward as it might seem, as there is no single global authority that defines a "country." Instead, it is decided by a combination of international recognition and membership in global organizations [2].

Here is how that total of 195 is calculated:

• 193 Member States of the United Nations: These are countries that have been admitted into the UN, which serves as the most widely accepted indicator of sovereignty and international recognition [2].
• 2 Non-member Observer States: These are the Holy See (Vatican City) and the State of Palestine [2]. They maintain permanent observer status at the UN, which grants them official recognition as sovereign entities by the international community, even though they are not full member states [2].

Why the number can be debated:

• Recognition: Whether an entity is a "country" often depends on whether other established countries recognize it as such. Some territories, like Taiwan or Kosovo, have varying degrees of international recognition, meaning some countries consider them independent while others do not.
• Differing Criteria: Different organizations or contexts (such as sports, Olympics, or historic treaties) may count territories or autonomous regions differently than the United Nations does [3].

While 195 is the standard figure accepted by the UN [1, 2], you might see slightly different numbers in other contexts depending on whether they include disputed territories or dependencies.
