What is considered as gross density?

1. Only residential units

2. Streets

3. Parks

4. All of the above

The correct answer is: Streets

Gross density refers to the total number of units or people living in a specific area, measured in relation to the size of that area. This metric typically includes all built density within a defined space, not just residential units. The correct answer encompasses not only residential buildings but also the entirety of the land use in that area. This includes streets, parks, and other infrastructure that contribute to the overall density of the area. Therefore, all elements that occupy the land in the defined area contribute to its gross density, illustrating how population is distributed relative to the total land area. This holistic viewpoint is crucial for urban planners, as it allows them to understand the comprehensive use of land and how different elements — such as parks and streets — interact and function as part of the community fabric. By considering all of these components together, planners can make more informed decisions regarding land use, zoning, and infrastructure development.
