In 2023, there were 179,400 Christians living in Israel. Christians of Arabic ethnic background accounted for the majority, with 141,800 individuals. Non-Arab Christians comprised 37,600 people in the country.

The number of households registered as Jewish in Israel reached roughly 2.36 million in 2023. In the same year, 469,300 households were registered as Arab, while 93,700 households were registered as belonging to population groups of other religions.

As of 2023, the youngest population group by religion in Israel were Muslims, with a median age of 24 years. On the other hand, the religious group was that of Christians of Arab ethnicity, at 35 years. The median age among Jews, the most populous group in the country, was 31.6.

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.

Israel's population is aging steadily, with the median age projected to rise from 29 years in 2020 to 32 years by 2050. This demographic shift reflects global trends of increasing life expectancy and declining birth rates, though Israel maintained a relatively young population compared to many developed nations. The country's unique religious and cultural makeup contributed to regional variations in age distribution, presenting both opportunities and challenges for policymakers. Which region has the oldest population? As of 2023, over a quarter of Israelis were under the age of 14 years. The largest age group in the country being four-year olds and below. Interestingly, significant regional differences existed within the country when it came to age distribution and aging. While the median age in the Jerusalem district was below 24, Tel Aviv was the oldest region with an average age of over 34 years, highlighting significant demographic variations across different areas. How does religion influence demographics? Religious affiliation played a role in Israel's age structure and demographics. Muslims are the youngest religious group with a median age of 24 years, while Christians of Arab ethnicity are the oldest, at 35 years. Jews, the largest religious-ethnic group, had a median age of almost 32 years, but within the Jewish demographic, age and fertility varied greatly between people based on religiosity. These differences play a significant role in the country's population and future growth patterns.

The two towns in Israel with the largest Druze populations in 2022 were Daliyat al-Karmel and Yarka, with 17,600 and 17,500 Druze residents, respectively. Other concentration of the religious group resided in Maghar with 13,600 Druze residents, Beit Jann with 12,400. Majdal Shams, located in the Golan Heights, had 11,500 residents of whom 100 percent were Druze.
