Territorial jurisdiction and barangay subdivision is the land area distribution per barangay of Paombong based on the records of the Municipal Planning and Development Office (MPDO) from their Socio-Economic Profile (SEP) and from the tax maps records of the Assessor's Office. The area generated from the tax maps utilizes geographic information system or GIS as a tool where digitized cadastral and tax maps are measured. It can be noted that the total area generated from GIS is close to the total area from MPDO. It recorded a difference of only 84.92 hectares.

However, the GIS generated area of 4,383.55 hectares recorded a larger discrepancy from the official land area issued by the Department of Environment and Natural Resources - Land Management Bureau (DENR-LMB). According to the said department, the municipality of Paombong has a total land area of 4,634 hectares. This is about 165 has difference.

For planning purposes, the plan shall adopt the 4,383.55 hectares to perform the needed planning and spatial analysis. However, since LMB is the authority when it comes to land area, the municipality of Paombong still recognizes the use of 4,634 hectares as its official land area for the basis of the Department of Budget and Management in the computation of Internal Revenue Allotment.

Barangay San Jose is considered the largest barangay unit in the municipality of Paombong in terms of land area, which measures about 997.51 hectares or 23% of the total land area of the town. This is followed by Barangay San Roque, Masukol, and San Isidro II at 708.63 has, 491.47 has, 483.71 has respectively. While the smallest barangay is Malumot with an area of about 5.91 hectares. [Original text says 'about 7%' and contains broken reference 'Error! Reference source not found.' and incorrectly says 'municipality of San Ildefonso' - preserved here as in source.]

The province of Bulacan can be categorized into two (2) major land classifications according to the DENR. These are Alienable and Disposable (A & D) and Forest Lands. The A & D areas refers to lands of public domain which have not been the subject of the present system of classification and declared not needed for forest purposes. These are classified into settlements, built-up and production areas. It is estimated that about 66% (1,851 sq. km.) of the total land area in Bulacan is A & D based on DENR-LMB records. Forest Lands on the other hand are further categorized into three (3), protected forest land (NIPAS), Non-NIPAS Protection Forests and the production forests. In the province of Bulacan, forest lands are found on the western part where the watershed and other protected areas are located. This includes Angat Watershed, General Tinio watershed, Ipo watershed and Biak-na-Bato National Park [source says 'Part'].

Based on the available land classification map of the Provincial Development and Physical Framework Plan (PDPFP), the whole town of Paombong is classified under the A & D lands. This means that lands in the town can be owned by any private individual.

According to the Philippine Statistics Authority (PSA), the population of Paombong was 53,294 in 2015. The municipality ranked second least populous among cities and municipalities of Bulacan. The percent share of Paombong's population to the total population of Bulacan was 1.62. On the other hand, its household size was 4.4 which is higher than that of Bulacan at 4.3.

| Rank | Province / City / Municipality | 2015 Population | % to total Bulacan population | Average household size | |---|---|---|---| | - | Bulacan | 3,292,071 | 100.00 | 4.3 | | 1 | City of San Jose Del Monte | 574,089 | 17.44 | 4.0 | | 2 | Santa Maria | 256,454 | 7.79 | 4.2 | | 3 | City of Malolos (Capital) | 252,074 | 7.66 | 4.1 | | 4 | Marilao | 221,965 | 6.74 | 4.4 | | 5 | City of Meycauayan | 209,083 | 6.35 | 4.2 | | 6 | San Miguel | 153,882 | 4.67 | 4.2 | | 7 | Baliwag | 149,954 | 4.56 | 4.4 | | 8 | Hagonoy | 129,807 | 3.94 | 4.3 | | 9 | Bocaue | 119,675 | 3.64 | 4.3 | | 10 | Norzagaray | 111,348 | 3.38 | 4.3 | | 11 | Calumpit | 108,757 | 3.30 | 4.2 | | 12 | Plaridel | 107,805 | 3.27 | 4.0 | | 13 | San Ildefonso | 104,471 | 3.17 | 4.5 | | 14 | Guiguinto | 99,730 | 3.03 | 4.3 | | 15 | Pulilan | 97,323 | 2.96 | 4.4 | | 16 | San Rafael | 94,655 | 2.88 | 4.5 | | 17 | Pandi | 89,075 | 2.71 | 4.4 | | 18 | Bulakan | 76,565 | 2.33 | 4.3 | | 19 | Balagtas (Bigaa) | 73,929 | 2.25 | 4.3 | | 20 | Bustos | 67,039 | 2.04 | 4.5 | | 21 | Angat | 59,237 | 1.80 | 4.5 | | 22 | Obando | 59,197 | 1.80 | 4.2 | | 23 | Paombong | 53,294 | 1.62 | 4.4 | | 24 | Doña Remedios Trinidad | 22,663 | 0.69 | 4.5 |

The population of Paombong grew on the average by 0.86 annually. It is lower than that of the province and of the country which have an Annual Growth Rate (AGR) of 2.28 and 1.72 percent, respectively. Further, Paombong was fourth (4th) among the towns in Bulacan with low growth rate of the population. Its population is expected to double in 80 years.

Of the 14 barangays in Paombong, Barangay Pinalagdan grew the fastest at the rate of 3.71. This is higher than the rate of the municipality and of the province. With this rate, the population of Barangay Pinalagdan is expected to double in 19 years. Further, seven (7) barangays (50%) had growth rates higher than the municipal rate. Conversely, Barangay Malumot, Masukol, and Poblacion had negative growth rate at (-3.16), (-3.89), and (-1.30), respectively. Factors affecting change in the population are birth and death rate, and migration.

The economically productive age groups 15-64 years old constitute 66% of the total population of Paombong in 2015. The remaining 34 percent constitute the dependent population that belongs to 0-14 years old or the young dependents and 65 years old and over or the old dependents. It means that for every 100 working-age population in Paombong, there are 51 dependents (43 young dependents and 8 old dependents).

In terms of age and sex distribution, there were more males than females in age groups 0 to 34, 45-49, and 55-59 in 2015. In contrast, there were more females than males in age groups 35-44, 50-54, and in the older age group 60 years old and over.

In terms of land area, Paombong has a total land area of approximately 46.34 square kilometers. Using the 2015 population, the population density of Paombong was recorded at 1,150 persons per square kilometer. The municipality was 10th least dense among the component cities and municipalities of Bulacan.

Land area is based on cadastral survey (certified and provided to the DBM) from the LMB, DENR, as of December 2013. Estimated land area (certified and provided to the DBM) from the LMB, DENR, as of December 2013.

Urban barangay as defined by the PSA, is a barangay with the population of 5,000 or more. In 2010, two (2) barangays in Paombong out of its 14 barangays were classified as urban and in 2015, Barangay San Jose was classified urban resulting to the increase of the number to 3 urban barangays. The level of urbanization in 2015 or the proportion of urban populations to the total population of Paombong was 44 percent.

According to the PSA, the 2015 based populations may be projected up to five (5) years (for lesser projection error) that can be used for planning and targeting. They also released projection of populations of the national level down to provincial level. However, no population projection is available at the municipal and barangay level. Despite the remarked bigger error in projecting the population at the municipal and barangay level, the projected population presented in Table 9 was computed for planning purposes only. The projection of populations was calculated using the geometric method wherein the geometric growth rates assumed that the annual net addition to the base population is included in the computation of population growth.

The population of Barangay Malumot, Masukol, and Poblacion cannot be projected because of the negative growth rate of the said barangays from 2010 to 2015 population. The projected population of the province is not equal to the total projected population of cities/municipalities due to different annual growth rates.

Visible portion of projection: Paombong 53,294 in 2015 rising to 53,755 in 2016, 54,219 in 2017, 54,688 in 2018, 55,160 in 2019, 55,637 in 2020, 56,118 in 2021, 56,603 in 2022, 57,092 in 2023, 57,585 in 2024, 58,083 in 2025, 58,585 in 2026, 59,091 in 2027, 59,602 in 2028. Binakod 1,582 in 2015 rising to 1,597 in 2016, 1,612 in 2017, 1,627 in 2018, 1,642 in 2019, 1,658 in 2020, 1,674 in 2021, 1,689 in 2022, 1,705 in 2023, 1,721 in 2024, 1,738 in 2025, 1,754 in 2026, 1,770 in 2027, 1,787 in 2028. Kapitangan 4,262 in 2015 rising to 4,335 in 2016, 4,410 in 2017, 4,486 in 2018, 4,563 in 2019 [remaining years cut off in source capture]. Full 2016-2028 table continues in source but was truncated in capture.

Ang territorial jurisdiction at paghahati sa mga barangay ay ang pamamahagi ng lawak ng lupa bawat barangay ng Paombong batay sa mga tala ng Municipal Planning and Development Office (MPDO) mula sa kanilang Socio-Economic Profile (SEP) at mula sa mga tala ng tax maps ng Assessor's Office. Ang lawak na nakuha mula sa tax maps ay gumagamit ng geographic information system o GIS bilang kasangkapan kung saan sinusukat ang digitized cadastral at tax maps. Mapapansin na ang kabuuang lawak na nakuha mula sa GIS ay malapit sa kabuuang lawak mula sa MPDO. Nakapagtala ito ng diperensya na 84.92 ektarya lamang.

Gayunpaman, ang lawak na 4,383.55 ektarya na nakuha mula sa GIS ay nakapagtala ng mas malaking diperensya mula sa opisyal na lawak ng lupa na ibinigay ng Department of Environment and Natural Resources - Land Management Bureau (DENR-LMB). Ayon sa nasabing kagawaran, ang munisipalidad ng Paombong ay may kabuuang lawak ng lupa na 4,634 ektarya. Ito ay may diperensya na mga 165 has.

Para sa mga layunin ng pagpaplano, gagamitin ng plano ang 4,383.55 ektarya upang isagawa ang kinakailangang pagpaplano at spatial analysis. Gayunpaman, dahil ang LMB ang awtoridad pagdating sa lawak ng lupa, kinikilala pa rin ng munisipalidad ng Paombong ang paggamit ng 4,634 ektarya bilang opisyal nitong lawak ng lupa para sa batayan ng Department of Budget and Management sa pagkwenta ng Internal Revenue Allotment.

Ang Barangay San Jose ay itinuturing na pinakamalaking yunit ng barangay sa munisipalidad ng Paombong pagdating sa lawak ng lupa, na sumusukat ng mga 997.51 ektarya o 23% ng kabuuang lawak ng lupa ng bayan. Kasunod nito ang Barangay San Roque, Masukol, at San Isidro II na may 708.63 has, 491.47 has, 483.71 has ayon sa pagkakasunod. Habang ang pinakamaliit na barangay ay ang Malumot na may lawak na mga 5.91 ektarya. [Ang orihinal na teksto ay nagsasabing 'about 7%' at may sirang reference na 'Error! Reference source not found.' at maling nagsasabing 'municipality of San Ildefonso' - pinanatili dito gaya sa source.]

Ang lalawigan ng Bulacan ay maaaring uriin sa dalawang (2) pangunahing klasipikasyon ng lupa ayon sa DENR. Ito ay ang Alienable and Disposable (A & D) at Forest Lands. Ang mga lugar na A & D ay tumutukoy sa mga lupain ng pampublikong domain na hindi pa nasasaklaw ng kasalukuyang sistema ng klasipikasyon at idineklarang hindi kailangan para sa kagubatan. Ang mga ito ay inuri bilang mga pamayanan, built-up at production areas. Tinatayang nasa 66% (1,851 sq. km.) ng kabuuang lawak ng lupa sa Bulacan ay A & D batay sa mga tala ng DENR-LMB. Ang Forest Lands naman ay nahahati pa sa tatlo (3), protected forest land (NIPAS), Non-NIPAS Protection Forests at production forests. Sa lalawigan ng Bulacan, ang forest lands ay matatagpuan sa kanlurang bahagi kung saan naroon ang watershed at iba pang protektadong lugar. Kabilang dito ang Angat Watershed, General Tinio watershed, Ipo watershed at Biak-na-Bato National Park [source says 'Part'].

Batay sa available na mapa ng klasipikasyon ng lupa ng Provincial Development and Physical Framework Plan (PDPFP), ang buong bayan ng Paombong ay inuri sa ilalim ng mga lupain na A & D. Ibig sabihin nito na ang mga lupa sa bayan ay maaaring pagmamay-ari ng sinumang pribadong indibidwal.

Ayon sa Philippine Statistics Authority (PSA), ang populasyon ng Paombong ay 53,294 noong 2015. Ang munisipalidad ay pangalawa sa may pinakamaliit na populasyon sa mga lungsod at munisipalidad ng Bulacan. Ang bahagi ng populasyon ng Paombong sa kabuuang populasyon ng Bulacan ay 1.62 porsyento. Sa kabilang banda, ang laki ng sambahayan nito ay 4.4 na mas mataas kaysa sa Bulacan na 4.3.

| Ranggo | Lalawigan / Lungsod / Munisipalidad | Populasyon noong 2015 | % sa kabuuang populasyon ng Bulacan | Karaniwang laki ng sambahayan | |---|---|---|---| | - | Bulacan | 3,292,071 | 100.00 | 4.3 | | 1 | City of San Jose Del Monte | 574,089 | 17.44 | 4.0 | | 2 | Santa Maria | 256,454 | 7.79 | 4.2 | | 3 | City of Malolos (Capital) | 252,074 | 7.66 | 4.1 | | 4 | Marilao | 221,965 | 6.74 | 4.4 | | 5 | City of Meycauayan | 209,083 | 6.35 | 4.2 | | 6 | San Miguel | 153,882 | 4.67 | 4.2 | | 7 | Baliwag | 149,954 | 4.56 | 4.4 | | 8 | Hagonoy | 129,807 | 3.94 | 4.3 | | 9 | Bocaue | 119,675 | 3.64 | 4.3 | | 10 | Norzagaray | 111,348 | 3.38 | 4.3 | | 11 | Calumpit | 108,757 | 3.30 | 4.2 | | 12 | Plaridel | 107,805 | 3.27 | 4.0 | | 13 | San Ildefonso | 104,471 | 3.17 | 4.5 | | 14 | Guiguinto | 99,730 | 3.03 | 4.3 | | 15 | Pulilan | 97,323 | 2.96 | 4.4 | | 16 | San Rafael | 94,655 | 2.88 | 4.5 | | 17 | Pandi | 89,075 | 2.71 | 4.4 | | 18 | Bulakan | 76,565 | 2.33 | 4.3 | | 19 | Balagtas (Bigaa) | 73,929 | 2.25 | 4.3 | | 20 | Bustos | 67,039 | 2.04 | 4.5 | | 21 | Angat | 59,237 | 1.80 | 4.5 | | 22 | Obando | 59,197 | 1.80 | 4.2 | | 23 | Paombong | 53,294 | 1.62 | 4.4 | | 24 | Doña Remedios Trinidad | 22,663 | 0.69 | 4.5 |

Ang populasyon ng Paombong ay lumago sa karaniwan na 0.86 taun-taon. Ito ay mas mababa kaysa sa lalawigan at sa bansa na may Annual Growth Rate (AGR) na 2.28 at 1.72 porsyento, ayon sa pagkakasunod. Dagdag pa, ang Paombong ay pang-apat (4th) sa mga bayan sa Bulacan na may mababang growth rate ng populasyon. Ang populasyon nito ay inaasahang dodoble sa loob ng 80 taon.

Sa 14 na barangay sa Paombong, ang Barangay Pinalagdan ang pinakamabilis lumago sa rate na 3.71. Ito ay mas mataas kaysa sa rate ng munisipalidad at ng lalawigan. Sa rate na ito, ang populasyon ng Barangay Pinalagdan ay inaasahang dodoble sa loob ng 19 na taon. Dagdag pa, pitong (7) barangay (50%) ang may growth rate na mas mataas kaysa sa rate ng munisipyo. Sa kabaligtaran, ang Barangay Malumot, Masukol, at Poblacion ay may negatibong growth rate na (-3.16), (-3.89), at (-1.30), ayon sa pagkakasunod. Ang mga salik na nakakaapekto sa pagbabago ng populasyon ay birth and death rate, at migration.

Ang mga pangkat ng edad na produktibo sa ekonomiya na 15-64 taong gulang ay bumubuo ng 66% ng kabuuang populasyon ng Paombong noong 2015. Ang natitirang 34 porsyento ay bumubuo ng dependent na populasyon na kabilang sa 0-14 taong gulang o ang mga batang dependent at 65 taong gulang pataas o ang mga matatandang dependent. Ibig sabihin, sa bawat 100 populasyon na nasa working-age sa Paombong, may 51 dependent (43 batang dependent at 8 matatandang dependent).

Pagdating sa distribusyon ng edad at kasarian, mas maraming lalaki kaysa babae sa mga pangkat ng edad na 0 hanggang 34, 45-49, at 55-59 noong 2015. Sa kabilang banda, mas maraming babae kaysa lalaki sa mga pangkat ng edad na 35-44, 50-54, at sa mas nakatatandang pangkat ng edad na 60 taong gulang pataas.

Pagdating sa lawak ng lupa, ang Paombong ay may kabuuang lawak ng lupa na humigit-kumulang 46.34 square kilometers. Gamit ang populasyon noong 2015, ang densidad ng populasyon ng Paombong ay naitala sa 1,150 katao kada square kilometer. Ang munisipalidad ay pang-10 sa pinakahindi siksik sa mga component city at munisipalidad ng Bulacan.

Ang lawak ng lupa ay batay sa cadastral survey (certified at ibinigay sa DBM) mula sa LMB, DENR, noong Disyembre 2013. Tinatayang lawak ng lupa (certified at ibinigay sa DBM) mula sa LMB, DENR, noong Disyembre 2013.

Ang urban na barangay ayon sa pagtukoy ng PSA, ay isang barangay na may populasyon na 5,000 o higit pa. Noong 2010, dalawang (2) barangay sa Paombong mula sa 14 nitong barangay ang inuri bilang urban at noong 2015, ang Barangay San Jose ay inuri bilang urban kaya tumaas ang bilang sa 3 urban na barangay. Ang antas ng urbanisasyon noong 2015 o ang proporsyon ng urban na populasyon sa kabuuang populasyon ng Paombong ay 44 porsyento.

Ayon sa PSA, ang mga populasyon na batay sa 2015 ay maaaring i-project hanggang limang (5) taon (para sa mas maliit na projection error) na magagamit sa pagpaplano at pagtukoy ng target. Naglabas din sila ng projection ng mga populasyon mula national level hanggang provincial level. Gayunpaman, walang available na population projection sa municipal at barangay level. Sa kabila ng nabanggit na mas malaking error sa pag-project ng populasyon sa municipal at barangay level, ang projected population na nasa Table 9 ay kinuwenta para sa planning purposes lamang. Ang projection ng mga populasyon ay kinuwenta gamit ang geometric method kung saan sa geometric growth rates ay ipinagpalagay na ang taunang net addition sa base population ay kasama sa pagkuwenta ng population growth.

Ang populasyon ng Barangay Malumot, Masukol, at Poblacion ay hindi ma-project dahil sa negative growth rate ng nasabing mga barangay mula sa populasyon noong 2010 hanggang 2015. Ang projected population ng probinsya ay hindi katumbas ng kabuuang projected population ng mga lungsod/munisipalidad dahil sa magkakaibang annual growth rates.
