Between 1948 and 1967, very few Arab citizens of Israel identified openly as "Palestinian", and an "Israeli-Arab" identity, the preferred phrase of the Israeli establishment and public, was predominant. Public expressions of Palestinian identity, such as displays of the Palestinian flag or the singing and reciting of nationalist songs or poetry were illegal. With the end of military administrative rule in 1966 and following the 1967 war, national consciousness and its expression among Israel's Arab citizens spread. A majority then self-identified as Palestinian, preferring this descriptor to Israeli Arab in numerous surveys over the years. In a 2017 telephone poll, 40% of Arab citizens of Israel identified as "Arab in Israel / Arab citizen of Israel", 15% identified as "Palestinian", 8.9% as "Palestinian in Israel / Palestinian citizen of Israel", and 8.7% as "Arab"; the focus groups associated with the poll provided a different outcome, in which "there was consensus that Palestinian identity occupies a central place in their consciousness".
