- Absence of military (notes): This list shows countries that have no permanent army, whose defense has been assigned to non-military forces such as the police, or is assumed by the military forces from other countries by virtue of a treaty. Each entry describes the current status of each country on regards to its defense.
- Armed forces personnel: Total armed forces (2000)
- Armed forces personnel per 1000: Total armed forces (2000). Figures expressed per thousand population for the same year.
- Branches: The names of the ground, naval, air, marine, and other defense or security forces
- Expenditures > Percent of GDP: Current military expenditures as an estimated percent of gross domestic product (GDP).
- Imports > USD: Arms transfers cover the supply of military weapons through sales, aid, gifts, and those made through manufacturing licenses. Data cover major conventional weapons such as aircraft, armored vehicles, artillery, radar systems, missiles, and ships designed for military use. Excluded are transfers of other military equipment such as small arms and light weapons, trucks, small artillery, ammunition, support equipment, technology transfers, and other services."
- Manpower > Reaching military age annually > Males: The number of draft-age males and females entering the military manpower pool in any given year and is a measure of the availability of draft-age young adults.
- Manpower reaching military age annually > Males: This entry is derived from Military > Manpower reaching military age annually, which gives the number of males and females entering the military manpower pool (i.e., reaching age 16) in any given year and is a measure of the availability of military-age young adults.
- Military branches: This entry lists the service branches subordinate to defense ministries or the equivalent (typically ground, naval, air, and marine forces).
- Military expenditures: This entry gives spending on defense programs for the most recent year available as a percent of gross domestic product (GDP); the GDP is calculated on an exchange rate basis, i.e., not in terms of purchasing power parity (PPP). For countries with no military forces, this figure can include expenditures on public security and police.
- War deaths: Battle-related deaths are deaths in battle-related conflicts between warring parties in the conflict dyad (two conflict units that are parties to a conflict). Typically, battle-related deaths occur in warfare involving the armed forces of the warring parties. This includes traditional battlefield fighting, guerrilla activities, and all kinds of bombardments of military units, cities, and villages, etc. The targets are usually the military itself and its installations or state institutions and state representatives, but there is often substantial collateral damage in the form of civilians being killed in crossfire, in indiscriminate bombings, etc. All deaths--military as well as civilian--incurred in such situations, are counted as battle-related deaths."
