Abstract: Methods, apparatus, and systems to collect audience measurement data are disclosed. An example system includes at least one non-transitory machine readable storage medium including instructions which, when executed, cause a machine to at least: generate behavior data developed during a first time period based on first media data and user data corresponding to one or more users of a household, the user data to include demographic information for the one or more users associated with the household, identify second media data during a second time period different than the first time period, the second media data identified without identification of the one or more users of the household, and associate the demographic information to the second media data based on the behavior data generated during the first time period associated with the one or more users.

Abstract: Methods, apparatus, and systems to collect audience measurement data are disclosed. Disclosed example systems include a first processor to collect (i) first media identification data corresponding to a first time period and (ii) second media identification data corresponding to a second time period after the first time period, the first media identification data and the second media identification data associated with a monitored location. Disclosed example systems also include a second processor to (i) develop behavior data based on the first media identification data and people meter data collected during the first time period with a people meter associated with the monitored location and (ii) identify an audience member associated with the second media identification data based on the behavior data and without access to any people meter data corresponding to the second time period.

Abstract: Methods, apparatus, and systems to collect audience measurement data are disclosed. A disclosed example system including means for collecting audience identification data and first media identification data during a first time period, the means for collecting to stop performing data collection after audience member behavior data has been developed based on the first media identification data and the audience identification data, means for accessing second media identification data during a second time period, the second media data collected via a service provider, means for developing the audience member behavior data based on the first media identification data and the audience identification data, and means for identifying an audience member associated with the second media identification data based on the audience member behavior data.

Abstract: Methods, apparatus, and systems to collect audience measurement data are disclosed. A disclosed example method includes collecting first media data and audience identification data via a metering device. Audience member behavior data is developed based on the first media data and the audience identification data. Second media data is accessed after the metering device has been removed. The second media data is collected by a service provider associated with the second media data. The removal of the metering device occurring after the audience member behavior data has been developed. Audience members associated with the second media data are identified based on the audience member behavior data.

A disclosed example method includes collecting first media data and audience identification data, the audience identification data being collected by prompting audience members in the monitored household to self-identify using a meter while the audience members are exposed to first media provided by a first media system. Audience member behavior is developed data based on the first media data and the audience identification data. The meter is deactivated after the audience member behavior data has been developed. Second media data is collected after the audience member behavior data has been developed without collecting audience identification data, the collecting of the second program identification data occurring while the audience members are exposed to second media. The audience members associated with the second media data are identified based on the audience member behavior data.
