Population of Ilocos Norte increased at the rate of 1.00 percent annually
Based on the 2010 Census of Population and Housing (2010 CPH), the province of Ilocos Norte posted a total population of 568,017 persons as of May 1, 2010. This is larger by 53,776 persons compared to its total population of 514,241 persons counted in the 2000 CPH. The increase in the population count from 2000 to 2010 translated to an average annual population growth rate (PGR) of 1.00 percent. This is lower than the 1.08 percent annual PGR of the province between the census years 1990 and 2000.
