The invention discloses a method and apparatus for performing flow statistics based on an MAC address. The method comprises the following steps: obtaining a plurality of connection handshake requests sent by a terminal to a plurality of wireless access points, wherein the connection handshake requests comprise an MAC address of the terminal; separately determining distance information according to the signal intensity of the connection handshake requests, wherein the distance information comprises distances between the terminal and different wireless access points; and determining the current position information according to the distance information, and counting the passenger flow of a position corresponding to the position information according to the position information statistics. According to the method, the passenger flow corresponding to the terminal can be very conveniently counted by using the position information of the terminal, by adoption of the method, the manpower can be saved, the changes of the passenger flow can be quickly counted, and the statistical efficiency of the passenger flow is high.
