The 2015 census of Malaysia reported a population of 2,636,000 in Sarawak, making it the fourth most populous state.

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.. How many percentages lower is the 1.8% average population growth rate compared to the national average?
