It is one of the island's fastest-growing settlements, with a population gain of 51,000 between 2010 and 2019, the highest of any township/city or district. The city has attracted migration both because of its proximity to Hsinchu City and the Hsinchu Science and Technology Park, and because the Hsinchu County government has focused most of its infrastructure here.
