Frequently asked questions
Employee headcount is a total number of employees that are currently working in a company.
The historical headcount data is the number of employees that were working in the company over the past months and even years.
This historical employee data is valuable if you want to identify high growth companies or track companies that are enduring layoffs.
Employee headcount growth is calculated by comparing how many employees were working in the company in different points of time.
Take the subtract the old value from the new value, divide the number by the old value, and multiply it by 100.
For example, if you have 15 employees working in the company in July, 2023, and 145 employees in July, 2024, your formula would be: ((145-15)/15 )*100. This company has experienced 867% headcount growth.
If you want to track company headcount changes, you can find relevant information in company's annual reports, company website, social media, or job postings.
