In 1960, the population of Casiguran was 6,900. This was almost doubled by the 1970s when population was 12,128, an increase of about 76% (5.8% annual average growth rate). Between 1970 and 1975, there was a marked decreased in the number of population from 12,128 to 11,670. This reduction was due to deteriorated peace and order, which forced some of the population to move away. The trend reversed by 1980, with an increase of 19% or an annual average growth rate increase of 3.86%. Increasing population continued during the succeeding censal years (1980 to 1995) but with a declining annual average population growth rate. This is attributed to the gradual stoppage of logging operations in the area. Many workers involved in this trade were not original residents, so when the jobs were no longer available, they left. Between 1995 and 1999 there was a significant increase of the annual average population growth rate to 4.36%. With this present growth rate, the municipality of Casiguran was expected to have an additional 25% increase in its 2009 projected population level.
