Passage: Following the withdrawal of the SNA, the WSLF continued their insurgency. By May 1980, the rebels, with the assistance of a small number of SNA soldiers who continued to help the guerrilla war, controlled a substantial region of the Ogaden. However, by 1981 the insurgents were reduced to sporadic hit-and-run attacks and were finally defeated. In addition, the WSLF and SALF were significantly weakened after the Ogaden War. The former was practically defunct by the late 1980s, with its splinter group, the Ogaden National Liberation Front  operating from headquarters in Kuwait. Even though elements of the ONLF would later manage to slip back into the Ogaden, their actions had little impact. For the Barre regime, the invasion was perhaps the greatest strategic blunder since independence, and it weakened the military. Almost one-third of the regular SNA soldiers, three-eighths of the armored units and half of the Somali Air Force  were lost. The weakness of the Barre administration led it to effectively abandon the dream of a unified Greater Somalia. The failure of the war aggravated discontent with the Barre regime; the first organized opposition group, the Somali Salvation Democratic Front , was formed by army officers in 1979. The United States adopted Somalia as a Cold War ally from the late 1970s to 1988 in exchange for use of Somali bases, and a way to exert influence upon the region. A second armed clash in 1988 was resolved when the two countries agreed to withdraw their militaries from the border.
Question: When did the WSLF lose control over a substantial region of the Ogaden?

Passage: The 2015 census of Malaysia reported a population of 2,636,000 in Sarawak, making it the fourth most populous state. However, this population is distributed over a large area resulting in Sarawak having the lowest population density in the country with only 20people per km2. Although it has a low population density, the average population growth rate of 1.8%, from 2000 to 2010, is very close to the national average of 2.0%. In 2014, 58% of the population resided in urban areas with the remainder in rural areas, but over the next 10 years it is predicted that the urban population would rise to 65%. , the birth rate in Sarawak was 16.3 per 1000 individuals, the mortality rate was 4.3 per 1000 population, and the Infant mortality was 6.5 per 1000 live births.
