UNRWA classifies them as those who left Israel in 1948, left the West Bank and Gaza Strip in 1967, were expelled after 1967 and were allowed to stay abroad and subsequently were not allowed to return to Israel, as well as their descendants.

The definition and number of Palestinian refugees may vary depending on the approach, administrative, legal and political definitio

The number of Palestinian refugees is estimated at 5 million, a figure that, according to the United Nations Relief and Works Agency (RWA) and UNICEF, includes about 700,000 Palestinians who fled or were displaced in 1948.

Palestinian refugees in the West Bank and East Jerusalem live in recognized Palestinian refugee camps, and at least 1.5 million registered Palestinian refugees live in these camps.

Some 2.2 million of the people who have fled to Israel since 1948 live in Gaza and Jerusalem. At least 4.4 million Palestinians, or 3.8% of the total number of registered Palestinians in Israel, live in a recognized "Palestinian refugee camp" or one of its camps in the West Bank or near the West Bank, including in East Israel and the East Bank.

About 1.5 million Palestinians, or 3.8% of the total number of registered Palestinians in the West Bank, live in a camp about 10 miles northeast of Tripoli.

Israel claims that it is not responsible for the "Palestinian refugee problem," because it is the result of a war imposed on it by an invading Arab army. It says that only a small percentage of those who have fled should be considered refugees today - an idea vehemently opposed by the Palestinian leadership, which relies on UNRWA figures.

UNRWA declares that the Palestinians are and will remain an occupied people until the General Assembly declares an end to the conflict. In other words, the return of "Palestinian refugees" would not lead to a "return" of the existing "Israeli-Jewish" population.

Israelis claim Arab countries should welcome their "Palestinian brothers and sisters" and help them integrate into their society. Arab countries believe that if they accept them, they will destroy the possibility of their own state, there is no doubt about that. "
