Rural – urban migration is significant in Bintulu because of greater job availability in the town . Since 2007 , new residents have started several squatter areas in Bintulu due to inability to find affordable housing , around Kidurong Industrial estate and Sungai Sebatang . To address the issue , several low @-@ cost housing projects were initiated by BDA and Sarawak state government to relocate the squatters . The state government planned to achieve zero squatters status by the year 2020 . Bintulu also saw the rise in the number of residential and commercial properties such as double @-@ storeyed terraced houses , terraced shopoffices , Kidurong Commercial Centre , and Time Square Shopping Mall . Residential properties has shown a 20 % price increase from 2011 to 2013 .
