By far the two most common forms of citizenship are by birth (where one is born) or by descent (nationality of one or both parents).
The World Factbook lists both of these citizenship types and whether they are used by any particular country. The
Factbook also indicates whether dual citizenship is recognized by a country and what the residency requirements are before applying for naturalization in a country. The "Citizenship" entry may be found in the Government section.

Did you know that more than three-quarters of the world’s countries have a maritime boundary of some sort. As such, they have an exclusive economic zone (EEZ), which is a sea zone – set forth by the 1982 UN Convention on the Law of the Sea - over which a country has special rights regarding the exploration and use of marine resources. An EEZ stretches from a country’s mean-low tide baseline at its coast out to 200 nautical miles. Most maps do not show EEZs, but The World Factbook’s World Oceans map does (under the References tab>Regional and World Maps>World Oceans; the PDF version is the most informative, particularly when enlarged). More than one-third of the world’s ocean area falls within an EEZ.

The "Capital" entry (under Government) is where visitors to
The World Factbook will find information related to time. This placement is because the
Factbook indicates the time difference in a country relative to the time observed in Washington, DC. The "Capital" entry is also where information on daylight savings time and time zones may be found.
Did you know that only about a third of all countries - and only about one-fifth of the world's inhabitants - use daylight savings time? Find more detailed information on time zones and daylight savings time under World>Government>Capital.

Groundwater can take 50 years to just traverse 1 km (0.6 mi). Find many more fascinating geographic facts about our world and its oceans in the "Geographic overview" of the World entry.
