Porac is an important source of granite and a tamping ground of minerals.

Porac is home to the Mekeni Food Corporation, an "AAA" Meat Processing Plant accredited with the National Meat Inspection Service (NMIS). Being classified under the "AAA" category, it is qualified to market its products, not just in the local, but in the international market as well. This means that it is compliant to all government regulatory requirements to assure food quality and safety in its operations (Sun Star, 2006).

In 2014, Ayala Land and Leonio Land embarked on developing a mixed-used estate in Porac known as Alviera. The development project combines business, residential, recreational, leisure, and institutional. The local government dubbed Alviera as the regional growth center of Central Luzon.[1] Now, it is a premiere tourist destination in the north, and the Philippines' hub for karting with the presence of the Pampanga International Circuit.

The municipal government is divided into three branches: executive, legislative and judiciary. The judicial branch is administered solely by the Supreme Court of the Philippines. The executive branch is composed of the mayor and the barangay captains for the barangays. The legislative branch is composed of the Sangguniang Bayan (town assembly), Sangguniang Barangay (barangay council), and the Sangguniang Kabataan for the youth sector.

Since the founding of the town of Porac in 1867, various Roman Catholic structures have been built in the area to aid in the religious practices of the devout Kapampangans. As of writing, three notable Spanish-era religious structures are extant within the municipality. The largest of the three, the Santa Catalina de Alejandria Church is located at Barangay Poblacion and still functions as one of Porac's main parochial structures. The other two are currently utilized as barangay chapels.

The Santa Catalina de Alejandria parish church is under the jurisdiction of the Roman Catholic Archdiocese of San Fernando. Its original structure, built in 1872, is largely intact but slight revisions have been made to the inside. It underwent restoration in the 1980s. The church is 52 metres (171 ft) long, 12 metres (39 ft) wide and 9 metres (30 ft) high.

In the earthquake of 2019, the church belfry has been destroyed a day after Easter Sunday. Rebuilding operations are planned with call for donations to restore the church bell tower.

The 1861 Pio Chapel is a circular chapel built by Don Felino Gil, founder of the Escuela de Artes y Oficios (now the Don Honorio Ventura Technical State University).

Another vintage chapel is located at Barangay Dolores, north of the Porac town proper. The Our Lady of Sorrows Chapel was said to be built by the Dolores family within the old Hacienda Dolores in 1856. The chapel, like the Pio chapel, is currently utilized as a community chapel. The chapel boasts of a slender octagonal belfry and Doric columns adorning the two-level façade. Notable features of the chapel are finials found on both levels of the façade.

The area in and around Babo Balukbuk in Porac has strong indications of human habitation, according to investigations published on the University of the Philippines Archaeological Studies Program website. Later test excavations confirmed this conclusion through the presence of materials dated around 12th century to 17th century C.E.
