Numerical estimates of the amount of Palestinians who fled from the State of Israel in 1947-1949 range from 500,000 to 800,000 with most historians choosing a number in the low 700,000s like 720,000. They primarily fled to Jordan, but a large number also fled to Egypt, Lebanon, and Syria. With the partial exception of Jordan, none of these countries has provided citizenship or acceptance for Palestinian refugees.
Numerical estimates of Jews who fled Arab countries from 1947-1952 are between 600,000 and 1,000,000 with most historians choosing a number in the mid 800,000s like 850,000. Of these emigrants, 500,000 settled in Israel and the remaining ones went to France, the United States, Canada, or the United Kingdom. All of these former refugees have become citizens in either Israel or the other countries to which they fled.
Additionally, when Israel captured the Golan Heights from Syria in 1967, most Syrian Muslims fled the area in order to remain in Syria. However, the Syrian Druze remained in the area and still live there under Israeli Occupation.
The main reason is probably the fact that Israel still exists, and shows no sign of being willing to evaporate.

Migration can be voluntary or forced, and can occur within a country (internal migration) or across international borders (international migration).
