A headcount is a count of the number of individuals employed by a company or organization at a given point in time. It is a commonly used metric in human resources and is often used to track the size of a company's workforce over time. The headcount can be used to track the overall growth of a company, as well as changes in the number of employees in different departments or locations. It can also be used to calculate employee-to-employee ratios or to measure productivity. Headcounts are usually done on a specific date and can be used for internal or external reporting.
