This is a list of countries and dependent territories by population. It includes sovereign states, inhabited dependent territories and, in some cases, constituent countries of sovereign states, with inclusion within the list being primarily based on the ISO standard ISO 3166-1. For instance, the United Kingdom is considered as a single entity while the constituent countries of the Kingdom of the Netherlands are considered separately. In addition, this list includes certain states with limited recognition not found in ISO 3166-1.
The population figures do not reflect the practice of countries that report significantly different populations of citizens domestically and overall. Some countries, notably Thailand, do not report total population, exclusively counting citizens; for total populations an international agency must issue an estimate.
