Like much of the northern part of the Bogor Regency, the district is largely made up of huge industrial parks and areas, along with many warehouses and factories, making it a huge contribution to the district's industry.

Asides from industrial areas, Cileungsi is also populated by many commuters, and can be considered a bedroom community. It features a lot of real estate housing, combined with another housing area to the west, called Cibubur. As a matter of fact, the housing area of Cibubur itself is beginning to extend to Cileungsi's boundaries, starting from the early-2000s.

The eastern portion of Cileungsi is home to a huge recreational park, featuring large gardens with tropical plants and plantations, as well as a waterpark, Taman Wisata Mekarsari.
