The Office of the United Nations High Commissioner for Human Rights (OHCHR) verified a total of 46,085 civilian casualties during Russia's invasion of Ukraine as of May 31, 2025. Of them, 32,744 people were reported to have been injured. However, OHCHR specified that the real numbers could be higher. How many people have died during the war in Ukraine? OHCHR has estimated the number of deaths of civilians, or non-armed individuals, in Ukraine at 13,341 since the start of the war on February 24, 2022. The highest death toll was recorded in March 2022, at over 3,900. The figures on soldier deaths are reported by Russia and Ukraine’s governmental authorities, but they cannot be verified at this point and thus need to be taken with caution. Conflict-related deaths in Ukraine from 2014 to 2021 After Russia annexed Crimea in 2014, Ukraine has seen a military conflict between the government and the Russia-supported separatist regions of Donetsk and Luhansk. OHCHR estimates that between 14,200 and 14,400 people, including civilians and military personnel, were killed in relation to that conflict from April 14, 2014, to December 31, 2021. Of them, at least 3,400 were civilians.

The First World War saw the mobilization of more than 65 million soldiers, and the deaths of almost 15 million soldiers and civilians combined. Approximately 8.8 million of these deaths were of military personnel, while six million civilians died as a direct result of the war; mostly through hunger, disease and genocide. The German army suffered the highest number of military losses, totaling at more than two million men. Turkey had the highest civilian death count, largely due to the mass extermination of Armenians, as well as Greeks and Assyrians. Varying estimates suggest that Russia may have suffered the highest number of military and total fatalities in the First World War. However, this is complicated by the subsequent Russian Civil War and Russia's total specific to the First World War remains unclear to this day.

Proportional deaths In 1914, Central and Eastern Europe was largely divided between the empires of Austria-Hungary, Germany and Russia, while the smaller Balkan states had only emerged in prior decades with the decline of the Ottoman Empire. For these reasons, the major powers in the east were able to mobilize millions of men from across their territories, as Britain and France did with their own overseas colonies, and were able to utilize their superior manpower to rotate and replace soldiers, whereas smaller nations did not have this luxury. For example, total military losses for Romania and Serbia are around 12 percent of Germany's total military losses; however, as a share of their total mobilized forces these countries lost roughly 33 percent of their armies, compared to Germany's 15 percent mortality rate. The average mortality rate of all deployed soldiers in the war was around 14 percent.

Unclarity in the totals Despite ending over a century ago, the total number of deaths resulting from the First World War remains unclear. The impact of the Influenza pandemic of 1918, as well as various classifications of when or why fatalities occurred, has resulted in varying totals with differences ranging in the millions. Parallel conflicts, particularly the Russian Civil War, have also made it extremely difficult to define which conflicts the fatalities should be attributed to. Since 2012, the totals given by Hirschfeld et al in Brill's Encyclopedia of the First World War have been viewed by many in the historical community as the most reliable figures on the subject.

The highest number of civilian casualties in Ukraine during the Russian invasion that began on February 24, 2022, was recorded in March 2022, with 4,312 people killed and 3,018 injured. In May 2025, 183 civilian deaths were verified by the Office of the United Nations High Commissioner for Human Rights (OHCHR),

Since the terrorist organization Hamas launched its attacks on Israeli soil on October 7, 2023, around 1,200 Israelis died, and 5,431 were injured. Through retaliation attacks by the Israeli armed forces against Hamas in Gaza, 56,156 Palestinians were killed, and 132.239 were injured. As of January 2025, the number of Palestinian deaths in the West Bank was 924, due to the on going conflict. Information on the data situation Data on the number of fatalities and injuries are based on the UNOCHA (United Nations Office for the Coordination of Humanitarian Affairs) reporting by both parties to the conflict. The respective data sources were named for the purpose of transparency. It must be stated that in the case of wars and other conflicts, objective data collection is almost impossible, and reports are based on estimates. At the same time, it needs to be noted that some parties to the conflict may use numbers and data selectively for their own agenda. Hamas attacks on Israel on October 7th, 2023 Before October 2023, there had been four wars between Israel and Hamas. The current conflict is already the deadliest, and the death toll is certain to rise. The new escalation of violence in the Middle East started after the militant Palestinian group Hamas attacked Israel in the early hours of October 7, 2023. An estimated 2,200 rockets were fired by Hamas from Gaza toward Israeli targets, hitting civilian buildings and military facilities. Hamas fighters entered the Israeli territory, killing around 1,200 of Israeli citizens. In the weeks that followed, the Israeli military conducted an aerial bombardment and launched a ground offensive in Gaza. Humanitarian pauses allowed aid to get into Gaza, but fighting has continued since a weeklong cease-fire ended on December 1, 2023. Operation Iron Swords and the humanitarian situation of Gaza Initially, Israel reacted to the Hamas attacks with further isolation of the Gaza Strip, cutting off the supply of electricity, fuel, and drinking water. As of November 6, 2023, water supply to parts of the Gaza Strip has been resumed. The Israeli Defense Forces (IDF) summoned the Palestinians to evacuate the northern part of the Gaza Strip towards the south of Gaza in the direction of the Egyptian border. This affects around 1.93 million people out of the 2.06 million inhabitants of Gaza. According to the UN, over one million people are internally displaced inside the Gaza Strip. Some trucks with relief supplies could infrequently enter the territory via the Rafah border from Egypt. This Israeli military operation is one of the longest-lasting in Gaza, and over 6,000 bombs were already dropped by the IDF.

The Korean War was an international military conflict which lasted from June 1950 until July 1953, which pitted the communist forces of North Korea, the Soviet Union, and the People's Republic of China against South Korea and a U.S.-led UN force comprised of troops from over 20 additional countries. The war was the United States' first major military engagement of the Cold War, the period of rivalry and heightened tension between the world's two superpowers, the U.S. and Soviet Union. While the war was one of the deadliest in the Cold War and the 20th century in general, it resulted in a stalemate between the North and South, with the boundary between the two countries remaining to this day at the 38th parallel line. The two countries remain technically at war to the present day, as the South's dictator, Syngman Rhee, refused to sign the peace agreement which in practice ended the fighting in the war.

U.S. military deaths in Korea

The majority of U.S. military fatalities during the Korean War were battle deaths (63 percent), with a smaller number of deaths while missing (12 percent), deaths while captured (eight percent), or deaths from battle wounds (seven percent). In addition, around three percent of deaths were from airplane crashes which were not caused by hostile forces, with another seven percent dying of other causes unrelated to battle. In total around 36,000 U.S. military servicemembers were killed in Korea, out of a total of around 40,000 deaths for the UN forces combined. The war was the United States' second deadliest conflict of the Cold War, as well as its fifth deadliest ever, after the Vietnam War, World War I, World War II, and the Civil War.

The Holocaust was the systematic extermination of Europe's Jewish population in the Second World War, during which time, up to six million Jews were murdered as part of Nazi Germany's "Final Solution to the Jewish Question". In the context of the Second World War, the term "Holocaust" is traditionally used to reference the genocide of Europe's Jews, although this coincided with the Nazi regime's genocide and ethnic cleansing of an additional eleven million people deemed "undesirable" due to their ethnicity, beliefs, disability or sexuality (among others). During the Holocaust, Poland's Jewish population suffered the largest number of fatalities, with approximately three million deaths. Additionally, at least one million Jews were murdered in the Soviet Union, while Hungary, Latvia, Lithuania, the Netherlands and Yugoslavia also lost the majority of their respective pre-war Jewish populations. The Holocaust in Poland In the interwar period, Europe's Jewish population was concentrated in the east, with roughly one third living in Poland; this can be traced back to the Middle Ages, when thousands of Jews flocked to Eastern Europe to escape persecution. At the outbreak of the Second World War, it is estimated that there were 3.4 million Jews living in Poland, which was approximately ten percent of the total population. Following the German invasion of Poland, Nazi authorities then segregated Jews in ghettos across most large towns and cities, and expanded their network of concentration camps throughout the country. In the ghettos, civilians were deprived of food, and hundreds of thousands died due to disease and starvation; while prison labor was implemented under extreme conditions in concentration camps to fuel the German war effort. In Poland, six extermination camps were also operational between December 1941 and January 1945, which saw the mass extermination of approximately 2.7 million people over the next three years (including many non-Poles, imported from other regions of Europe). While concentration camps housed prisoners of all backgrounds, extermination camps were purpose-built for the elimination of the Jewish race, and over 90% of their victims were Jewish. The majority of the victims in these extermination camps were executed by poison gas, although disease, starvation and overworking were also common causes of death. In addition to the camps and ghettos, SS death squads (Einsatzgruppen) and local collaborators also committed widespread atrocities across Eastern Europe. While the majority of these atrocities took place in the Balkan, Baltic and Soviet regions, they were still prevalent in Poland (particularly during the liquidation of the ghettos), and the Einsatzgruppen alone are estimated to have killed up to 1.3 million Jews throughout the Holocaust. By early 1945, Soviet forces had largely expelled the German armies from Poland and liberated the concentration and extermination camps; by this time, Poland had lost roughly ninety percent of its pre-war Jewish population, and suffered approximately three million further civilian and military deaths. By 1991, Poland's Jewish population was estimated to be just 15 thousand people, while there were fewer than two thousand Jews recorded as living in Poland in 2018.

The deadliest state-based conflict in Africa in 2023 was the civil war in Sudan between the Sudanese government and the rebel group Rapid Support Forces (RSF). It is estimated that more than 5,000 people were killed in the conflict that year. By comparison, nearly 3,900 were killed in Somalia, Kenya, and Ethiopia in the conflict between the Government of Somalia and Al-Shabaab. The war in Sudan has seen millions of people displaced, and many face hunger and starvation. Rising terrorism in Africa In recent years, some African states have been suffering from increasing terrorist activity due to a weak state and a poor security apparatus. For instance, Burkina Faso and Mali made up two of the four countries ranked highest on the global terrorism index in 2023, and in the Democratic Republic of the Congo, the number of terrorist attacks rose from less than 200 in 2018 to around 900 in 2021. Many of the state-based conflicts on the continent are between a state and a terrorist organization. Increasing number of coups The poor state infrastructure in some African states has led to a surge in coup d'états on the continent since 2020, especially in Western Africa, where there have been successful coups in Mali, Burkina Faso, Niger, Guinea, and Gabon in recent years. Worldwide, Thailand is the country with the highest number of successful coup d'états since the Second World War.

In 1938, the year before the outbreak of the Second world War, the countries with the largest populations were China, the Soviet Union, and the United States, although the United Kingdom had the largest overall population when it's colonies, dominions, and metropole are combined. Alongside France, these were the five Allied "Great Powers" that emerged victorious from the Second World War. The Axis Powers in the war were led by Germany and Japan in their respective theaters, and their smaller populations were decisive factors in their defeat. Manpower as a resource In the context of the Second World War, a country or territory's population played a vital role in its ability to wage war on such a large scale. Not only were armies able to call upon their people to fight in the war and replenish their forces, but war economies were also dependent on their workforce being able to meet the agricultural, manufacturing, and logistical demands of the war. For the Axis powers, invasions and the annexation of territories were often motivated by the fact that it granted access to valuable resources that would further their own war effort - millions of people living in occupied territories were then forced to gather these resources, or forcibly transported to work in manufacturing in other Axis territories. Similarly, colonial powers were able to use resources taken from their territories to supply their armies, however this often had devastating consequences for the regions from which food was redirected, contributing to numerous food shortages and famines across Africa, Asia, and Europe. Men from annexed or colonized territories were also used in the armies of the war's Great Powers, and in the Axis armies especially. This meant that soldiers often fought alongside their former-enemies. Aftermath The Second World War was the costliest in human history, resulting in the deaths of between 70 and 85 million people. Due to the turmoil and destruction of the war, accurate records for death tolls generally do not exist, therefore pre-war populations (in combination with other statistics), are used to estimate death tolls. The Soviet Union is believed to have lost the largest amount of people during the war, suffering approximately 24 million fatalities by 1945, followed by China at around 20 million people. The Soviet death toll is equal to approximately 14 percent of its pre-war population - the countries with the highest relative death tolls in the war are found in Eastern Europe, due to the intensity of the conflict and the systematic genocide committed in the region during the war.

Throughout the period in which the United States was in an armed conflict with the Communist-led government and insurgency in Vietnam (referred to as the "Vietnam War" in the U.S. and the "Resistance War against the United States" in Vietnam), around 40 percent of the 8.7 million U.S. military service personnel were stationed in South-East Asia. Of these personnel in the theatre of war, around two percent were killed during the conflict.

This war was part of the wider Cold War of the second half of the 20th century, where the rivalry between the superpowers of the United States and Soviet Union dominated the post-World War II era. During this period the U.S. stationed much of its remaining five million service personnel outside of active conflict zones, especially in strategically important countries such as (West) Germany, South Korea, and Japan, in addition to those stationed at home.

In 1890, the average person born in the area of present-day North Korea could expect to live to 26 years old, a rate which would see only marginal change until the annexation of the Korean peninsula by the Empire of Japan in 1910. As Japanese large scale industrialization and modernization reforms would begin in the peninsula (building on the Gwangmu reforms of the previous administration), life expectancy would begin to increase rapidly as standards of living rose across the region. As a result, life expectancy would rise by twenty years between 1920 and 1940, however this growth would slow during the 1940s, as Korea lost approximately half a million people (or 2% of its population) during the Second World War. Following the war, the peninsula was split into two separate states, with the north and south each administered by the Soviet Union and the U.S. respectively (although both militaries had largely left the peninsula within a few years). In 1950, as tensions grew between the two governments regarding the legitimate rulers of the peninsula, North Korea invaded the South and set in motion the Korean War. The war would last for three years, and result in the deaths of approximately three million Koreans (with the North suffering heavier losses than the South); this caused the life expectancy in North Korea to plummet from over 49 years to less than 38 years in the first half of the 1950s.

Life expectancy in North Korea would quickly recover in the post-war years, as the Soviet Union would provide significant economic aid to the country. As a result, life expectancy would return to pre-war levels by the end of the decade and resume its steady rise until the collapse of the Soviet Union in 1991. After peaking at 70 years in the early 1990s, it is estimated that life expectancy fell by nearly seven years in the early 1990s as the country would face extreme medical and food shortages following the end of Soviet aid. U.S. estimates put the death toll of these famines at more than half a million people in the 1990s. In the past two decades, life expectancy has slowly increased once more in North Korea, returning to pre-famine levels once more in 2015, and it is now estimated that the life expectancy from birth in North Korea in 2020 is approximately 72 years old.

Despite the outbreak of the Russia-Ukraine war in 2022, and the Israel-Hamas war since October 2023, which have come to dominate international news, the overall number of conflicts worldwide decreased since 2013. In 2023, there were *** instances of violent crisis recorded globally, compared to ** wars and ** limited wars. What is a conflict? According to the new conflict methodology in Heidelberg, the HIIK understands a political conflict as a positional difference regarding values relevant to a society between at least two involved actors, for example ethnic or religious groups or governments. The conflict must be carried out using observable and interrelated conflict means that lie beyond established regulatory procedures and threaten a core state function or the order of international law, or hold out the prospect to do so. Regarding the intensity of a political conflict the HIIK distinguishes five levels of intensity: dispute, non-violent crises, violent crises, limited war, and war. These levels of conflict are distinguished by the level of physical violence applied in the course of conflict. The last three are violent conflicts, whereas a dispute is a political conflict carried out completely without resorting to violence; in a non-violent crisis, one of the actors is threatened with violence. Violent conflicts are measured by the instruments for the use of force (use of weapons and use of personnel) and the consequences of the use of force (casualties, refugees and demolition). In 2023, the highest number of wars was recorded in Sub-Saharan Africa.

Europe's Jewish population in 1939 was around 9.5 million people, and it is estimated that six million of these were ultimately killed by 1945. The persecution of German Jews escalated during the interwar period, particularly after Hitler's ascent to power in 1933, and again after Kristallnacht in 1938. However, the scale of this increased drastically following the German invasions of Poland in 1939 and the USSR in 1941, when Germany annexed regions with some of the largest Jewish populations in Europe. Extermination Camps As part of the "Final Solution to the Jewish Question", the Nazi occupiers established six extermination camps in present-day Poland; these were Auschwitz-Birkenau, Belzec, Chelmno, Majdanek***, Sobibor, and Treblinka. Prisoners, mostly Jews, were transported from all over Europe to these camps. Upon arrival, the majority of victims were sent directly to purpose-built chambers or vans, where they were murdered with carbon monoxide or Zyklon B gas. A relatively small number of prisoners were also forced to dispose of the victims' bodies, which often included their own family members, friends, or persons known to them. Most of the deceased were incinerated, and many of the camp records were destroyed; this means that precise figures for the number of deaths in extermination camps will never be known. It has been estimated that at least 2.7 million Jews were murdered in these six camps; over two thirds of these were killed at Auschwitz or Treblinka. Einsatzgruppen After extermination camps, the most common method of murder was through mass shootings. The majority of these shootings were not carried out by regular soldiers, but specialized task forces known as "Einsatzgruppen". Each group was just a few hundred men each, but they were responsible for some of the largest individual acts of genocide in the war. The largest of these took place at Babi Yar, near Kyiv in 1941, where almost 35,000 victims were beaten, humiliated, and then shot over a two day period. The Einsatzgruppen were most active in the annexed Soviet territories (although additional regiments were active in Poland and the Balkans), and their ranks were often bolstered by local volunteers. It has been estimated that Einsatzgruppen were responsible for the genocide of more than two million people in fewer than six years.

In Europe, the Baltic countries of Latvia and Lithuania had the highest and third highest homicide rates respectively in 2022. Latvia had the highest rate at over four per 100,000 inhabitants. Meanwhile, the lowest homicide rate was found in Liechtenstein, with zero murders The most dangerous country worldwide Saint Kitts and Nevis is the world's most dangerous country to live in in terms of murder rate. The Caribbean country had a homicide rate of 65 per 100,000 inhabitants. Nine of the 10 countries with the highest murder rates worldwide are located in Latin America and the Caribbean. Whereas Celaya in Mexico was listed as the city with the highest murder rate worldwide, Colima in Mexico was the city with the highest homicide rate in Latin America, so the numbers vary from source to source. Nevertheless, several Mexican cities rank among the deadliest in the world when it comes to intentional homicides. Violent conflicts worldwide Notably, these figures do not include deaths that resulted from war or a violent conflict. While there is a persistent number of conflicts worldwide, resulting casualties are not considered murders. Partially due to this reason, homicide rates in Latin America are higher than those in countries such as Ukraine or the DR Congo. A different definition of murder in these circumstances could change the rate significantly.

Turks and Caicos Islands saw a murder rate of ***** per 100,000 inhabitants, making it the most dangerous country for this kind of crime worldwide as of 2024. Interestingly, El Salvador, which long had the highest global homicide rates, has dropped out of the top 29 after a high number of gang members have been incarcerated. Meanwhile, Colima in Mexico was the most dangerous city for murders. Violent conflicts worldwide Notably, these figures do not include deaths that resulted from war or a violent conflict. While there is a persistent number of conflicts worldwide, resulting casualties are not considered murders. Partially due to this reason, homicide rates in Latin America are higher than those in Afghanistan or Syria. A different definition of murder in these circumstances could change the rate significantly in some countries. Causes of death Also, noteworthy is that murders are usually not random events. In the United States, the circumstances of murders are most commonly arguments, followed by narcotics incidents and robberies. Additionally, murders are not a leading cause of death. Heart diseases, strokes and cancer pose a greater threat to life than violent crime.
