## About Residential Density Calculator (Formula)

The Residential Density (RD) is a measure of how many residential units are located within a given area of land. It is often used in urban planning and real estate to understand the population density and land use efficiency. The formula for calculating Residential Density (RD) is relatively simple:

**Residential Density (RD) = Total Number of Residential Units / Total Land Area**

Where:

- Total Number of Residential Units: This represents the total number of housing units or residential buildings within a specific area.
- Total Land Area: This represents the total land area in which these residential units are located, typically measured in square meters, square feet, acres, or any other appropriate unit of area.

To calculate the Residential Density, you divide the total number of residential units by the total land area. The result will give you the number of residential units per unit of land area, which can be expressed as units per acre, units per square kilometer, or any other unit of land area that is convenient for your analysis.

For example, if you have 100 residential units on a piece of land that measures 5 acres in total, the Residential Density would be:

**RD = 100 units / 5 acres = 20 units per acre**

This means there are 20 residential units per acre of land in this specific area. Residential Density is an important metric in urban planning as it can help assess the efficiency of land use, plan infrastructure, and understand population distribution within a city or region.
