(p 87 & p 98)The pre-war population accounts for 9,473 persons, which is slightly less than one-third of the present population, whereas the rest are post-war immigrants. Some 10.000 persons settled since 1924, since the so called middle-class immigration.

Whether there was significant Arab immigration into
Palestine after the beginning of Jewish settlement there in the late 19th century has become a matter of some controversy. According to
Martin Gilbert, 50,000 Arabs immigrated to
Mandatory Palestine from the neighboring lands between 1919 and 1939 "attracted by the improving agricultural conditions and growing job opportunities, most of them created by the Jews".
[47] The Arab population of Palestine doubled during the mandatory period from 670 000 in 1922 to over 1.2 million in 1948. The estimates on the scope of Arab immigration to Palestine during this period range from insignificant numbers to almost 300 000.[

The
1931 census of Palestine considered the question of illegal immigration since the previous
census in 1922.
[55] It estimated that unrecorded immigration during that period may have amounted to 9,000 Jews and 4,000 Arabs.
[55] It also gave the proportion of persons living in Palestine in 1931 who were born outside Palestine: Muslims, 2%; Christians, 20%; Jews, 58%
In a 1974 study, Bachi proposed an average of 900 per year for the number of Muslims who were detected as illegal immigrants but not deported.
[56] He noted the impossibility of estimating illegal immigration that was undetected, or the fraction of those persons who eventually departed.
[56] He suggested, though qualifying it as a "mere guess", that the unexplained increase in the Muslim population between 1922 and 1931 was due to a combination of unrecorded immigration (using the 1931 census report estimate) and undercounting in the 1922 census
