The terms country, state, and nation can have various meanings. Therefore, diverse lists of these entities are possible. Wikipedia offers the following lists:
the list of countries, listing countries in the sense of independent states (both those that are internationally recognized and generally unrecognized), inhabited dependent territories, and areas of special sovereignty.
the list of sovereign states, listing sovereign states with information on the extent of their sovereignty. It includes both states widely recognized (de jure) to be sovereign and entities that claim sovereignty while exercising de facto control over (part of) their claimed territory.
There are varying degrees and forms of dependence, commonly distinguished from other subnational entities in that they are not considered to be part of the motherland or mainland of the governing State. In most cases they also represent a different order of separation. A subnational entity typically represents a division of the State proper, while a dependent territory might be an overseas territory that enjoys a greater degree of autonomy. For instance, many of them have more or less separate legal systems from the governing States. Varies among different legal and constitutional traditions, these territories may or may not be considered part of the States.
Currently there are 60 dependencies on this list, not including those listed as under China, Finland, and Russia. Out of the list below, Australian, British and New Zealand territories are part of the Commonwealth realm - their governing States are in personal union under the same British monarch. All claims south of 60 degrees south (in Antarctica) are not recognised or are disputed. They are italicised. Uninhabited territories or territories with no permanent population are marked with hash keys/number symbols (#).
