A computer-readable medium containing instructions for a computer to perform a method for tracking visitors at bar or night club establishments having scanners capable of scanning the driver's license of each visitor entering the establishment. After scanning, the validity of the license is verified, as is whether the visitor is above the legal drinking age, and an identification code is associated with each such visitor. The time that the scan took place is recorded and the gender of the visitor is ascertained. The information is sent to and stored on the system server. The system server tallies the gender information for visitors associated with an identification code at each establishment. The population, tallied gender ratio and a calculated gender rate ratio for each establishment are displayed on a system website. System subscribers are permitted to access the displayed information on the system website.
