A computerized method of transmitting content to a first device and a second device may include receiving a first identifier and first location data of the first device, and a second identifier and second location data of the second device. The method may include comparing the first location data with the second location data, and generating a co-location score in response to the comparison. The method may include determining that the co-location score is greater than a threshold, and responsively generating household data indicative of a relationship between the first device and the second device. The method may further include generating and transmitting a report indicating the relationship to a content provider that transmits content to the first device and the second device.
