The results are attributed to the IOC country code as currently displayed by the IOC database. Usually, a single code corresponds to a single National Olympic Committee (NOC). When different codes are displayed for different years, medal counts are combined in the case of a simple change of IOC code (such as from HOL to NED for the Netherlands) or simple change of country name (such as from Ceylon to Sri Lanka). As the medals are attributed to each NOC, not all totals include medals won by athletes from that country for another NOC, such as before independence of that country (see individual footnotes for special cases such as combined teams). Names in italic are national entities that no longer exist. The totals of NOCs are not combined with those of their predecessors and successors.
The table is pre-sorted by the name of each Olympic Committee, but can be displayed as sorted by any other column, such as the total number of gold medals or total number of overall medals. To sort by gold, silver, and then bronze, sort first by the bronze column, then the silver, and then the gold. The table does not include the medals revoked (e.g., due to doping, etc.). Medal totals in this table are current as of the 2014 Winter Olympics in Sochi, and all changes in medal standings due to doping cases up to and including 20 May 2015 are taken into account.
For the 1900 Summer Olympics several countries are credited with appearances that are not considered official by the IOC. Only one of these cases concerns a medal. A gold medal that is officially added to France's total is given to Luxembourg.
Similar cases of disputed nationality affect the 1904 Summer Olympics. France is credited with a silver medal and Norway with two gold medals. In the table above these medals are listed under the United States. Furthermore, Newfoundland is occasionally listed as a separate country at the 1904 Olympics, and would be listed as a historical NOC without medals.
Other differences from the official table are based on disagreements about which events were Olympic.This affects several of the events in the 1900 and 1904 Olympics. In addition, some sources include the 1906 Intercalated Games when compiling their medal tables.
Germany has competed under five different designations, including as two separate teams at several Games. Sources vary in how they present the medals won by these teams. The table below shows sourced combinations of these teams, when applied to the updated medal totals from the main table.
SAA , EUA , GDR , FRG → GERGermany (GER) competed 1896–1952 and from 1992. Due the partition of Germany after World War II, Germany was represented by two teams at the 1952 Games — Germany (GER) and the Saar (SAA). The Saar was reintegrated back into the Federal Republic of Germany on 1 January 1957, and Saar athletes then competed for Germany. East Germany did not contribute athletes to the 1952 team, as the National Olympic Committee for the German Democratic Republic was only granted "provisional" recognition by the IOC in 1955. For the Games of 1956–1964, Germany participated as a Unified Team of Germany (EUA), representing the National Olympic Committees of both West Germany and East Germany. Retrospectively, the IOC uses the country code EUA for this team. After the NOC for the German Democratic Republic was granted full recognition by the IOC in 1968, East Germany (GDR) and West Germany (FRG) competed as an independent teams at the 1968-1988 Games.
YAR , YMD → YEM Prior to Yemeni unification in 1990, North Yemen participated as the Yemen Arab Republic (YAR) in 1984 and 1988, and South Yemen participated as the Yemen Democratic Republic (YMD) at the 1988 Games. After forming united republic Yemen (YEM) has participated since 1992.
ZZX Special code used by the IOC to refer to medals won by athletes of multiple nations competing together, which was common in early Games (1896–1904). These medals are not included in the respective totals for each nation represented by individual mixed team athletes.
TPE2 After the Chinese Civil War the Chinese Taipei (TPE) participated using the Republic of China designation at the 1956, 1960, 1972 and 1976 (winter) Games and using Taiwan designation at the 1964 and 1968 Games. In 1979, the IOC started to use Chinese Taipei to refer to this NOC, a compromise that was acceptable for the People's Republic of China (CHN) to start participating in the Olympic Games. Chinese Taipei name was first used in 1984. Participation of the Republic of China, representing all of China (including Taiwan), in 1932, 1936 and 1948 Games are not counted in Taiwan's participation total.
ABrunei's participation in the 1988 Games consisted only of a single official, but no competing athletes. This participation is not counted in Brunei's participation total.
BDjibouti at the 2004 Games took part in the Opening Ceremony, but neither athlete competed, so this participation is not counted in Djibouti's participation total.
CLiberia's athletes withdrew from 1980 Games after marching in the Opening Ceremony and took part of the boycott. This participation is not counted in Liberia's participation total.
DLibya marched in the opening ceremony of the 1964 Games, but then withdrew from competition. This participation is not counted in Libya's participation total.
ESuriname at the 1960 Games took part in the Opening Ceremony, but its lone athlete withdrew from Games due to a scheduling error. Participation of Suriname at the 1960 Games not recognized by IOC, so this participation is not counted in Suriname's participation total.
J Some sources consider Léon Thiércelin, a fencer who competed at the 1900 Games, of Haitian nationality and therefore the first Olympic appearance by Haiti. Participation of Haiti at the 1900 Games not recognized by IOC, so this participation is not counted in Haiti's participation total.
K Some sources consider Freydoun Malkom, a fencer who competed at the 1900 Games, of Persian nationality and therefore the first Olympic appearance by Iran. Participation of Iran at the 1900 Games not recognized by IOC, so this participation is not counted in Iran's participation total.
L Some sources consider Carlos de Candamo, a fencer who competed at the 1900 Games, of Peruvian nationality and therefore the first Olympic appearance by Peru. Participation of Peru at the 1900 Games not recognized by IOC, so this participation is not counted in Peru's participation total.
PaPb Sources are inconsistent regarding Albert Corey's participation for France in 1904. Although the Games report refers to Corey as a "Frenchman wearing the colors of the Chicago Athletic Association", the IOC attributes his medal in the marathon to the United States instead of France, and in contradiction, the medal in the four mile team race to a mixed team composed of athletes from multiple nations instead of just the United States.
QaQb In wrestling competition at the 1904 Summer Olympics Norway is credited with two gold medals by some sources, which the IOC attributes to United States.
RBob Fowler, an American marathon runner who competed at the 1904 Games, was a native Newfoundlander, Newfoundland is occasionally listed as a separate country at the 1904 Olympics, and would be listed as an historical NOC without medals. Participation of Newfoundland at the 1904 Games not recognized by IOC.
