An understanding of the growth and composition of Pateros’ population is basic to the formulation of the Pateros Comprehensive Land use Plan. Demographic analysis includes an evaluation of historic trends in population change within the locality, as well as an examination of the detailed characteristics of the town's household base. The following demographic analysis is presented in two parts, population trends and selected population characteristics.
Based on the 1995 census (the latest available), Pateros has a population of 55,286. This represented an increase of 7.54% from the last census in 1990. This makes for an annual growth rate of 1.46% which is lower than those of the National Capital Region (NCR) and the neighbor town Taguig but higher than neighbors Makati and Pasig. Trends from 1903 to 1995 shows Pateros experiencing rapid population growth from 1960 to 1990.
Barangay Sta. Ana composed the largest share of population with 40% while Sto Rosario-Kanluran and Aguho follows with 12% and 10%, respectively. Barangay Magtanggol has the lowest population share with 3%.
The growth rate, however, is on a decelerating trend. Based on the planning team’s analysis, the population growth rate will be around 0.67% by 2011. Projected population in 2000 is around 58,855 and in 2011 it will be about 64,811. Part of the explanation was that Pateros’ neighbor Taguig has been growing rapidly which probably absorbed would-be migrants to Pateros.
Females outnumber males in Pateros in 1995 with a ratio of 1: 0.94. Looking at the shape of the age-sex pyramid of the town, it is apparent that the town has a slowing growth trend since it is not a straight cone type (an indication of fast population growth). The age group in the 35 years old below predominates the population. By this time (2000) the pyramid shape would be straighter given the declining growth rate and the increasing longevity of the residents.
The mother tongue of the population suggests the ethnic background of the residents of the population. It could have implications in the culture and social aspects of the town. In the case of Pateros, around 85% of the total population are of Tagalog origin while other substantial number includes Waray, Bicol, Cebuano and Ilocano.
Pateros is among the most congested areas in NCR because of its small size and large population base. It has a density much greater than NCR and its neighbors. Barangays Aguho, Poblacion and the Sto. Rosario-Kanluran have the highest densities while Barangays Magtanggol and Sto. Rosario-Silangan have the lowest densities.
