Internally displaced Palestinians, also Internally displaced persons in Israel and Palestine, are Palestinian IDPs who fled or were expelled from their home in Mandatory Palestine by Jewish or Israeli forces, before and during the 1948 Arab-Israeli war, but who remained within the area that became the state of Israel. Palestinian IDPs in Israel are also referred to as present absentees. The term applies to the IDP's descendants too.
According to estimates from Palestinian NGO BADIL, there are 384,200 IDPs in Israel and 334,600 IDPs in the Palestinian territories.
In 1950, 46,000 out of the 156,000 Israeli Arabs in Israel were considered Present absentees.
IDPs are not permitted to live in the homes they formerly lived in, even if they were in the same area, the property still exists, and they can show that they own it. They are regarded as absent by the Israeli government because they were absent from their homes on a particular day, even if they did not intend to leave them for more than a few days, and even if they left involuntarily.
If the definition is restricted to those displaced in the 1948 war and its immediate aftermath and their descendants, some 274,000 Arab citizens of Israel - or 1 in 4 Palestinians in Israel - are internally displaced Palestinians.
The Internal Displacement Monitoring Centre estimated in 2007 that 150,000-420,000 internally displaced persons were living in Israel. The vast majority are Muslim (90%) and some 10% are Christian. There are no Druze among them "since no Druze village was destroyed in the 1948 war and no Druze left their settlements permanently." Organizations defending the rights of Palestinian Arab citizens of Israel also generally include the 110,000 Bedouin forced to move in a closed area under military rule in the Negev in 1949 in their estimates of internally displaced Palestinians. Other internally displaced persons included in these counts are those who were displaced by ongoing home demolitions enacted against unlicensed structures or in unrecognized villages. Estimates based on this broader definition place the total population of IDPs at anywhere between 250,000 - 420,000 people.
