Rabba lies on the historical King's Highway. It is situated on a thin semi-fertile plain, giving way to Wadi Ibn Hammad in the west, and the desert in the east. Located near the northern edge of the town is the Farming College, a branch of Mu'tah University.
Rabba was traditionally populated largely by the Majali and Zureikat families, the first of which has considerable political influence in the country. However, since 1948 when Israel was formed, many Palestinians, who left their homes in Palestine settled in Rabba as well, now accounting for about a third of the town's population.
