Inspired by an in-depth analysis recently published on Italia in Numeri, we decided to explore a crucial yet often overlooked dimension of the Israeli–Palestinian conflict: demographics. From 1922 to 2025, the population of this region has grown from about 750,000 people under the British Mandate to more than 12 million today, split between Israel, the West Bank and the Gaza Strip.
Our article traces this transformation through historical data, UN estimates, and demographic indicators:
- Who lived in Palestine before 1948 – Muslims, Christians, Jews, and small minorities.
- 1948 as the turning point: the birth of Israel and the Nakba for Palestinians.
- Israel’s remarkable demographic growth, driven by immigration and high fertility.
- The Palestinian demographic explosion, especially in Gaza, where the population rose from 240,000 in 1950 to over 2.3 million in 2023.
Through interactive charts and data visualizations, we show how the two populations followed parallel but very different paths – with long-term implications for resources, coexistence, and the fragile balance in the region.
Who Lived in Palestine Before 1948?
To fully grasp the roots of the Israeli–Palestinian conflict, it is essential to look back at the decades preceding 1948, when Palestine was under the British Mandate. At that time, the region had a mixed population, but with a balance very different from what would emerge after the creation of the State of Israel.
In 1922, at the beginning of British administration, Palestine had around 750,000 inhabitants. The vast majority were Muslim Arabs (about 78%), most of whom lived in rural villages and worked in agriculture. Around the main cities – Jerusalem, Nablus, Hebron, Jaffa, and Haifa – more urban communities had developed, often with strong local identities.
Alongside them, there was a significant minority of Christian Arabs (close to 10% in 1922), concentrated especially in Bethlehem, Jerusalem, and Nazareth. These communities played a key role in trade, education, and religious institutions, and represented an important element of Palestinian society.
The Jewish community, by contrast, made up just over 11% of the population in 1922 (around 84,000 people). It included both long-established Jewish families who had lived for centuries in holy cities such as Jerusalem, Safed, and Hebron, as well as new arrivals from the late 19th and early 20th century immigration waves (Aliyah). In the 1930s, as Nazism rose in Europe and anti-Semitic persecution intensified, Jewish immigration increased sharply. By 1944, the Jewish population exceeded half a million, roughly 30% of the total.
Smaller groups also existed: Druze, Circassians, and Armenians accounted for less than 1% of the population, but had deep roots in specific areas, particularly in Galilee and Jerusalem.
On the eve of 1948, Palestine was therefore a mosaic of religions and cultures: about two-thirds Arab (Muslims and Christians) and one-third Jewish. These figures, however, reveal more than just demographics – they highlight a fragile balance, already shaken by profound political and social transformations that would soon reshape the region.
1948: The Year Everything Changed
The year 1948 marked a turning point in Middle Eastern history. With the end of the British Mandate in Palestine, the United Nations approved a plan to partition the territory. On May 14, David Ben-Gurion officially declared the establishment of the State of Israel. Within minutes, the United States and the Soviet Union recognized the new state, while neighboring Arab countries responded with hostility, sparking the first Arab–Israeli war.
For Palestinians, 1948 is remembered as the Nakba – “the catastrophe.” Between 700,000 and 800,000 people were forced to leave their homes or were expelled. Entire villages were abandoned, daily life was shattered, and communities scattered. Many refugees fled to neighboring countries such as Lebanon, Jordan, and Syria, while others crowded into the Gaza Strip and the West Bank. This displacement created a diaspora that remains unresolved to this day, forming one of the central issues of the conflict.
From that moment on, demographics became a crucial lens for understanding the Israeli–Palestinian reality.
Israel’s population growth was driven by two main forces:
- Mass immigration of Jews from around the world, first from Europe and North Africa, later from the former Soviet Union.
- High birth rates, which reinforced the consolidation of the population within the new state.
For Palestinians, demographic trends had a very different meaning:
- In the territories that remained under Arab control after 1948 (Gaza, the West Bank, East Jerusalem), the population grew under precarious political and social conditions.
- Refugees fueled dispersed communities, creating a multi-generational issue that remains unresolved.
- Exceptionally high fertility rates ensured that, despite war, displacement, and economic hardship, the Palestinian population continued to expand rapidly.
Israel’s Population Growth (1950–2024)
Since 1950, Israel’s population has risen dramatically, from just over 1.3 million to more than 10 million in 2024. In the early years, immigration was the main driver. In 1951 alone, the migration balance reached an exceptional peak (+104 per thousand), fueled by waves of arrivals from Europe and North Africa. At the same time, birth rates were extremely high, exceeding 34 births per thousand, with fertility averaging more than 4.5 children per woman. This combination nearly doubled Israel’s population within a decade.
The 1960s and 1970s maintained strong momentum: birth rates gradually declined to around 25–27‰, but natural growth remained high, adding tens of thousands of people each year. By 1970 the country had surpassed 3 million inhabitants, approaching 4 million by the end of the decade.
The 1980s brought a slowdown. Birth rates fell to around 22‰, with fertility declining to about 3 children per woman. Growth continued, though at a steadier pace, with Israel’s population reaching 4.56 million in 1989. The following decade, however, saw another surge. The dissolution of the Soviet Union led to the arrival of over one million immigrants. Between 1990 and 2000, the population expanded from 4.8 to more than 6.3 million, fundamentally reshaping Israel’s social and economic structure. Birth rates remained high compared to European averages, hovering around 21‰.
In the 2000s and 2010s, growth stabilized. The population exceeded 7.7 million by 2010 and 9.3 million by 2020. Birth rates stayed remarkably high (20–21‰), mortality remained low (5–6‰), and fertility hovered around 3 children per woman – exceptional numbers for a developed nation. By 2024, Israel had crossed the symbolic threshold of 10 million residents.
In less than 75 years, Israel’s population grew more than sevenfold. High fertility, sustained immigration, and low mortality made Israel one of the fastest-growing populations in the developed world, with profound social, economic, and political consequences.
Palestinian Population Growth (1950–2025)
Palestinians experienced one of the most rapid demographic expansions in the Middle East. From fewer than one million inhabitants in 1950, their population grew to over 5.1 million by 2021. This growth reflects a fragile balance of natural increase, health conditions, and political context.
In the 1950s, Palestinian birth rates were among the highest in the world – more than 48 births per thousand, with fertility at 7.8 children per woman. Mortality, however, was also very high: in 1950, more than 142 infants died for every 1,000 live births, and life expectancy was only 46 years. Despite these challenges, the natural increase pushed the population from 945,000 to over 1.1 million in a single decade.
During the 1960s and 1970s, mortality began to decline sharply. Infant mortality dropped from 120‰ to below 90‰, and life expectancy rose above 55 years. Birth rates, however, remained extremely high, around 49–50‰, producing an annual increase of about 40,000 people. By 1970 the population had already doubled compared to 1950.
The 1980s and 1990s brought signs of demographic transition. Birth rates declined from 47‰ in 1980 to 42‰ in 1995, while fertility fell from 7 to about 6 children per woman. Infant mortality plummeted to below 30‰, and life expectancy surpassed 70 years. By 1995, the Palestinian population exceeded 2.6 million.
In the 2000s and 2010s, the transition accelerated. Birth rates dropped below 30‰, fertility declined to about 3.5 children per woman, and natural growth slowed, though still high (over 120,000 annually). The population reached 4 million in 2010 and more than 5 million in 2020. By 2021, Palestinians numbered 5.1 million, with life expectancy nearing 75 years.
The Gaza Strip: From Refuge to Overcrowding (1950–2025)
The Gaza Strip offers the most striking example of demographic change. In 1950, its population was about 240,000; by 2023 it had exploded to over 2.3 million – a tenfold increase in just over seventy years, in a territory of only 365 km².
Gaza City became both the administrative capital and the symbolic center of this growth. After 1948, when hundreds of thousands of Palestinians were displaced, many settled in Gaza and the refugee camps surrounding it. For many families, Gaza became both a place of refuge and a cage.
High fertility rates then drove relentless growth. Unlike other regions where population increases could be absorbed by new towns or rural settlements, Gaza’s closed borders and movement restrictions meant everything was compressed into the same small area. Gaza City, in particular, became the epicenter of this demographic squeeze, with crowded neighborhoods and high-rise buildings packed side by side.
The result is one of the highest population densities in the world. Hundreds of thousands of people live within a few square kilometers, with chronic shortages of basic services – from water to electricity. Despite hardship, Gaza City has remained vibrant, with bustling markets and children making up the majority of its population.
Today, however, this very concentration makes Gaza exceptionally vulnerable. Airstrikes and bombardments inevitably strike homes, schools, hospitals, and markets, as there are no empty spaces. The ongoing war has not only halted Gaza’s once-relentless population growth but reversed it. Projections for 2025 estimate a decline to about 2.25 million inhabitants, driven by mass civilian casualties and increasingly unlivable conditions.
