Population increased at the rate of 1.39 percent annually

Based on the 2010 Census of Population and Housing (CPH), the province of Nueva Vizcaya posted a total population of 421,355 persons as of May 1, 2010.  This is larger by 54,393 persons compared to its total population of 366,962 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 1.39 percent.  This is lower than the 1.99 percent annual PGR of the province between the census years 1990 and 2000.

If the average annual PGR recorded at 1.39 percent during the period 2000 to 2010 continues, the population of Nueva Vizcaya would double in 50 years.

Fifty years ago, the population of Nueva Vizcaya was only 113,824 persons.  This population size is less than one third of the population of the province in the 2010 CPH.
