Gaza City, with a population of over half a million residents, is the largest urban center and de-facto capital of the Gaza Strip, which itself has a total population of over 1.8 million. As of 2018, it is estimated that at least 1.3 million of the residents of the Gaza Strip are Palestinian refugees from other areas in historic Palestine, having fled to Gaza after the creation of the State of Israel in 1948. These refugee communities originally come from the many historic rural areas that surrounded the Gaza Strip, smaller towns and cities along the Mediterranean coast, as well as areas further afield such as Jaffa, 69 km north of Gaza on the coast, and Bir il-Sab‘, the largest city in the Nagab desert region (see Figure 1). Linguistically, many of these refugee communities are of Palestinian Arabic dialect backgrounds, although varieties of Arabic spoken in the Nagab are classified as originating in the Hijaz area of what is today Saudi Arabia (see Shahin 2007 on Palestinian Arabic and Henkin 2010 on Nagab Arabic).

加沙城拥有超过 50 万居民，是加沙地带最大的城市中心和事实上的首都，其总人口超过 180 万。截至 2018 年，据估计，加沙地带至少有 130 万居民是来自历史悠久的巴勒斯坦其他地区的巴勒斯坦难民，他们在 1948 年以色列国成立后逃往加沙。这些难民社区最初来自加沙地带周围的许多历史悠久的农村地区、地中海沿岸的小城镇和更远的地区，如加沙以北 69 公里的海岸上的雅法和加沙最大的城市比尔萨布Nagab 沙漠地区（见图 1）。从语言上讲，这些难民社区中有许多具有巴勒斯坦阿拉伯语方言背景，
