Jews were the dominant religious group in the Israel-Palestine region at the beginning of the first millennia CE, and are the dominant religious group there today, however, there was a period of almost 2,000 years where most of the world's Jews were displaced from their spiritual homeland. Antiquity to the 20th century Jewish hegemony in the region began changing after a series of revolts against Roman rule led to mass expulsions and emigration. Roman control saw severe persecution of Jewish and Christian populations, but this changed when the Byzantine Empire adopted Christianity as its official religion in the 4th century. Christianity then dominated until the 7th century, when the Rashidun Caliphate (the first to succeed Muhammad) took control of the Levant. Control of region split between Christians and Muslims intermittently between the 11th and 13th centuries during the Crusades, although the population remained overwhelmingly Muslim. Zionism until today Through the Paris Peace Conference, the British took control of Palestine in 1920. The Jewish population began growing through the Zionist Movement after the 1880s, which sought to establish a Jewish state in Palestine. Rising anti-Semitism in Europe accelerated this in the interwar period, and in the aftermath of the Holocaust, many European Jews chose to leave the continent. The United Nations tried facilitating the foundation of separate Jewish and Arab states, yet neither side was willing to concede territory, leading to a civil war and a joint invasion from seven Arab states. Yet the Jews maintained control of their territory and took large parts of the proposed Arab territory, forming the Jewish-majority state of Israel in 1948, and acheiving a ceasefire the following year. Over 750,000 Palestinians were displaced as a result of this conflict, while most Jews from the Arab eventually fled to Israel. Since this time, Israel has become one of the richest and advanced countries in the world, however, Palestine has been under Israeli military occupation since the 1960s and there are large disparities in living standards between the two regions.

In 1995, Israel had a Jewish population of approximately 4.5 million people, of whom approximately 1.75 million were born abroad. Over one million of these immigrants were born in Europe, with over 650,000 of these born in the former Soviet Union. Despite Poland having the largest Jewish population in the world in the pre-WWII years, the number of Polish Jewish migrants and descendents in Israel was relatively small in 1995 when compared to the USSR due to the impact of the Holocaust.

Outside of Europe, Morocco had the largest number of Jewish immigrants and descendents in Israel by 1995. Morocco had the largest Jewish population in the Muslim world when Israel was founded in 1948, with over 250,000 people. Many Moroccan Jews sought to emigrate to Israel at this time, but often faced resistance from authorities and local populations who believed the Jews would join in the fight against the Arab forces seeking to establish a Muslim state in Palestine. The government of Morocco then officially prohibited emigration to Israel after gaining independence from France in 1956, however this policy was reversed in 1961 whereby the Moroccan government began facilitating Jewish emigration to Israel in return for payments from Jewish organizations in the U.S. and Israel. By the 1970s, Morocco's Jewish population had fallen to less than 15 percent of its size in 1948.

The world's Jewish population has had a complex and tumultuous history over the past millennia, regularly dealing with persecution, pogroms, and even genocide. The legacy of expulsion and persecution of Jews, including bans on land ownership, meant that Jewish communities disproportionately lived in urban areas, working as artisans or traders, and often lived in their own settlements separate to the rest of the urban population. This separation contributed to the impression that events such as pandemics, famines, or economic shocks did not affect Jews as much as other populations, and such factors came to form the basis of the mistrust and stereotypes of wealth (characterized as greed) that have made up anti-Semitic rhetoric for centuries. Development since the Middle Ages The concentration of Jewish populations across the world has shifted across different centuries. In the Middle Ages, the largest Jewish populations were found in Palestine and the wider Levant region, with other sizeable populations in present-day France, Italy, and Spain. Later, however, the Jewish disapora became increasingly concentrated in Eastern Europe after waves of pogroms in the west saw Jewish communities move eastward. Poland in particular was often considered a refuge for Jews from the late-Middle Ages until the 18th century, when it was then partitioned between Austria, Prussia, and Russia, and persecution increased. Push factors such as major pogroms in the Russian Empire in the 19th century and growing oppression in the west during the interwar period then saw many Jews migrate to the United States in search of opportunity.

The two countries with the greatest shares of the world's Jewish population are the United States and Israel. The United States had been a hub of Jewish immigration since the nineteenth century, as Jewish people sought to escape persecution in Europe by emigrating across the Atlantic. The Jewish population in the U.S. is largely congregated in major urban areas, such as New York, Los Angeles, and Chicago, with the New York metropolitan area being the city with the second largest Jewish population worldwide, after Tel Aviv, Israel. Israel is the world's only officially Jewish state, having been founded in 1948 following the first Arab-Israeli War. While Jews had been emigrating to the holy lands since the nineteenth century, when they were controlled by the Ottoman Empire, immigration increased rapidly following the establishment of the state of Israel. Jewish communities in Eastern Europe who had survived the Holocaust saw Israel as a haven from persecution, while the state encouraged immigration from Jewish communities in other regions, notably the Middle East & North Africa. Smaller Jewish communities remain in Europe in countries such as France, the UK, and Germany, and in other countries which were hotspots for Jewish migration in the twentieth century, such as Canada and Argentina.

The estimated population of the Gaza Strip for 2023 was around 2.1 million people. The Palestinian population of Gaza is relatively young when compared globally. More than half of Gazans are 19 years or younger. This is due to the comparably high fertility rate in the Gaza Strip of 3.5 children per woman as of 2022.

Refugees are people who are recognized as refugees under the 1951 Convention Relating to the Status of Refugees or its 1967 Protocol, the 1969 Organization of African Unity Convention Governing the Specific Aspects of Refugee Problems in Africa, people recognized as refugees in accordance with the UNHCR statute, people granted refugee-like humanitarian status, and people provided temporary protection. Asylum seekers--people who have applied for asylum or refugee status and who have not yet received a decision or who are registered as asylum seekers--are excluded. Palestinian refugees are people (and their descendants) whose residence was Palestine between June 1946 and May 1948 and who lost their homes and means of livelihood as a result of the 1948 Arab-Israeli conflict. Country of asylum is the country where an asylum claim was filed and granted.

On October 7, 2023, in what many believe to be a breaking point between Israel and the Gaza Strip, Palestinian militant group Hamas led an invasion into Israel via the Gaza Strip, marking the first time direct contact was made on Israeli territory since the First Arab-Israeli War in 1948 and 1949. Following attacks on bordering communities and Israeli military bases, Israeli Prime Minister Benjamin Netanyahu formally declared war resulting in what is now an ongoing ground and aerial invasion in Gaza. As one of Israel's allies, many have been debating the responsibility of the United States and whether it should increase its military support. As of December 2024, 17 percent of Americans supported an increase in U.S. military aid to Israel.

Im Jahr 2023 gab es weltweit rund 16,8 Millionen Juden. Davon lebten die meisten Juden in Israel und in den USA. Die jüdische Bevölkerung wird immer größer Weltweit gibt es immer mehr Juden. Seit Ende des Zweiten Weltkrieges ist die Anzahl der Juden von elf Millionen auf 16,8 Millionen im Jahr 2023 angestiegen. Vor allem in den USA und in Israel ist die jüdische Bevölkerung am wachsen. In Israel wird generell seit Jahren ein positives Bevölkerungswachstum verzeichnet. Das liegt hauptsächlich an der hohen Fertilitätsrate. In Deutschland sind die Mitgliederzahlen in den jüdischen Gemeinden hingegen am sinken. Holocaust und Antisemitismus Die Nationalsozialisten begingen während ihrer Herrschaftszeit von 1933 bis 1945 einen Völkermord an mehreren Millionen Menschen, darunter sechs Millionen Juden. Die durch staatlichen Antisemitismus vorangetriebene NS-Ideologie sah die Vernichtungen von allem "unwerten Leben" vor, ihr erklärtes Ziel war die vollkommene Auslöschung des jüdischen Volkes und anderer Minderheiten. Auch heute noch sind antisemitische Einstellungen und Vorurteile in Deutschland in Teilen der Gesellschaft vertreten. Angesichts des Terrorangriffs der Hamas auf Israel Anfang Oktober 2023 häufen sich antisemitische Vorfälle auch in Deutschland.
