Albert Socin, noting an official Ottoman village list circa 1870, wrote that Beit Ummar had a total of 44 houses and a population of 133, though the population count included only men. Hartmann found that Bet Ummar had 60 houses. In 1883, the PEF's Survey of Western Palestine (SWP) described Beit Ummar as a "small but conspicuous village standing on the watershed, and visible from some distance on the north. An ancient road passes through it. Half a mile north-east is a good spring, ‘Ain Kufin. The mosque has a small tower to it. The surrounding neighbourhood is covered with brushwood." British Mandate era In the 1922 census of Palestine, conducted by the British Mandate authorities, Bait Ummar had a population of 829 inhabitants, all Muslims, increasing in the 1931 census to 1,135, still entirely Muslim, in 217 inhabited houses. In the 1945 statistics the population of Beit Ummar was 80 Jews and 1,600 Muslims, and the total land area was 30,129 dunams of land, according to the official land and population survey. 2,912 dunams were plantations and irrigable land, 12,879 were for cereals, while 55 dunams were built-up (urban) land. Jordanian era In the wake of the 1948 Arab–Israeli War, and after the 1949 Armistice Agreements, Beit Ummar came under Jordanian rule. It was annexed by Jordan in 1950. In 1961, the population of Beit Ummar was 2,103. Post-1967 Since the Six-Day War in 1967, Beit Ummar has been under Israeli occupation. The population in the 1967 census conducted by the Israeli authorities was 2,630. Beit Ummar became a municipality on April 17, 1997, after the dismantlement of the Israeli village council and Hussein Badr was appointed by the Palestinian National Authority. The current mayor is Nasri Sabarna. The town is currently located in Area B (civil affairs administered by the PNA) and Area C (civil and military affairs controlled by Israel). Israel has confiscated or expropriated approximately 4,000 dunams of village land in order to construct Israeli bypass roads and several Israeli settlements: Karmei Zur, Migdal Oz, Kfar Etzion and Efrat. The town is governed by a municipal council consisting of thirteen members including the mayor. Several people in the village have been shot and killed by Israeli soldiers or settlers during Israeli occupation. In January 2011, 17-year-old Yousef Ikhlayl was shot and killed during an altercation with Israeli settlers. In August 2014, Hashem Abu Maria was killed
