Demography

Among the six (6) cities and seventeen  (17) municipalities in Cavite, the city  of Imus ranked third in terms of population according to the 2010 records of the National Statistics Office (NSO). Dasmariñas and Bacoor placed first and second, respectively.

In 2010, the population of Imus was  recorded at 301,624. This absorbed  9.76% of the total population of the province recorded at 3,090,691.

From this  level , the population of Imus is projected to reach a high of 338,986 in 2012 ( the start of the planning period). The projection is based on the 4.43 percent growth rate achieved during the period covering 2010-2012 using the Geometric method.

A study of the Demographic trends from 1903-2012, reveals that the city experienced the biggest growth path of 8.17 percent in 1995.  From the 1990 total population of 119,783, the level rose to 177,408 in 1995.  This was 14 times the count of the first census recorded by the NSO taken in 1903.

In 1903, the population  of Imus   was registered at 12,912.  Over the fifteen year period between 1903 to 1918, the percentage of increase was only 8%.  Census records in 1939, 1948 and 1960 showed a two percent increase per census year, from 209%, 31% and 33%, respectively.  In 1970, the percentage of increase was 38%, a 5% increase from 1960.  In 1975, the percentage of increase dropped to 11% and then rose to 21% by 1980.  Figures in 1990 exhibited the biggest increase of 102%.  The level then decreased by 48% in 1995 and further fell down by 10% in 2000.  In 2010, the level moved up by 54%  in 2010 for an average annual growth of 4.43%.

The high growth in population during the period 1980 -1990   could be attributed to the influx of new settlers and increasing rate of in-migration to the locality.   Being near to the National Capital Region, the city absorbed most of the overspill population of the Metropolis. This is evident in the development of a number of residential   subdivisions which started during the decade of the   80’s.  The increase could also be due to the booming economic activity in Imus as part of CALABARZON growth corridor.

The  2012  population  of  Imus posted at 328,940   is  distributed to the  97  barangays  of  the city. Buhay na Tubig had the largest demographic count among the barangays with 25,212 persons. Pasong Buaya II with 21,387, came next.  Alapan I-A and Carsadang Bago II followed with 13,978 and 12,143, respectively.

On the other hand, Poblacion I-C with a total population of 208 was  the least populated area. Ranking second was Poblacion I-B with 324 Poblacion II-B  followed with 538 people.

Households population, on the other hand, was placed at 80,356, bringing   the average household   size to about   four (4)  persons  per household.
