cALABARZON MAPLOGO CALABARZON Calabarzon formally known as Southern Tagalog Mainland and designated as CALABARZON Region, is an administrative region in the Philippines. The region comprises the five (5) provinces, Cavite, Laguna, Batangas, Rizal, and Quezon, whose names form the acronym CALABARZON. Its regional center is Calamba in Laguna.

Situated just south of Metro Manila in southwestern Luzon, the region is the most populous in the Philippines, having 14,414,774 inhabitants in 2015, and is also the country's second most densely populated after NCR. Prior to its creation as a region, Calabarzon, together with Mimaropa, formed the historical region known as Southern Tagalog, until they were separated in 2002 by virtue of Executive Order No. 103.

The region is home to some of the most important Philippine historical figures, most notable of which is the Philippines' national hero, Jose Rizal, who was born in Calamba.

The region has 19 cities (18 component cities and the highly urbanized city of Lucena). Antipolo is the most populous city in CALABARZON Region and is the seventh most populous city in the Philippines while San Pedro City is the most densely populated city in the whole region.


Increasing Number of Filipinos and Changing Demographic Age Structure

The latest Population Census recorded about 14 million Filipinos living in CALABARZON in 2015. The pace of growth has fluctuated for the past three decades and now displays a decreasing trend, from 3.07% annual growth rate in 2000-2010 period to 2.58% in 2010-2015. An indication that there are about 300 thousand Filipinos added to the region’s population every year.

About one-third of Filipinos in the region were residing in the provinces of Cavite and Laguna, both relatively near Metro Manila and can be accessed easily through land travel. The numerous housing projects situated in the said provinces also relates to the increase in population due to in-migration.

     Lucena City 196,000 246,000 266,000 1.49

Among the five provinces comprising the region, Cavite had the biggest population in 2015 with 3.68 million, followed by Laguna with 3.04 million, Rizal with 2.88 million, and Batangas with 2.69 million. Quezon (excluding Lucena City) had the smallest population with 1.86 million. Refer to Table 1. 

Cavite was the fastest growing province in the region with an average annual population growth rate (PGR) of 3.37 percent during the period 2010 to 2015. It was followed by Rizal (2.88 percent), Laguna (2.47 percent), and Batangas (2.41 percent). Quezon (excluding Lucena City) posted the lowest provincial PGR of 1.23 percent.

Figure 2 displays a narrowing population base from 2000 to 2010 which indicates a decrease in birth rate. The change in age structure, seen by the widening sides of the pyramid from ages 0-14 up to ages 15-64 reflects a larger working age population through the years.

CALABARZON’s population is relatively young. Based on the 2010 population census, about 32.18 percent or 4 million Filipinos were below 15 years of age; 64 percent or 8 million Filipinos were between 15 to 64 years old (consisting the working or productive ages); and 3.82 percent or 182 thousand Filipinos were aged 65 and over. Young population means a continuing increase in population due to the large cohorts of young women who will soon enter the childbearing years and contribute to the fertility level and increasing number of young dependents in the region.

Table 2. Dependency Ratio: CALABARZON

Source: 2000 and 2010 Census of Population and Housing
Year Young Dependency Ratio Old Dependency Ratio Total Dependency Ratio
2000 59.1 5.8 64.9
2010 50.3 2.3


The 2010 population estimate in the region indicates about 50 young (14 years and below) and 2 old (65 years and above) dependents for every 100 working-age (15-64 years old) persons. Looking at Table 2 though, the region’s dependency ratio has significantly decreased from 64.9 in the year 2000 to 50.6 in the year 2010. This indicates that in a span of 10 years, the number of working population is almost equal to the number of dependents. Such relationship of dependents to working age population provides an ideal scenario for demographic dividend in CALABARZON.
