Abstract: Methods, apparatus, systems, and articles of manufacture to calibrate payload information are disclosed. An example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry. The processor circuitry is to execute the instructions to obtain (a) passive measurement data and (b) background active measurement (BAM) data from panelists in a market of interest, the BAM data associated with network usage metrics of panelist wireless devices undisturbed by panelist behavior. The processor circuitry is also to execute the instructions to assign a first share of the passive measurement data and a second share of the BAM data to particular areas within the market of interest, the first share based on a number of passive measurement occurrences in a first one of the particular areas, the second share based on a number of BAM occurrences in the first one of the particular areas.

Abstract: Methods, apparatus, systems and articles of manufacture to reduce a processing burden on a hardware processor estimating a number of actual mobile devices in a geographic region are disclosed. An example method includes accessing mobile device advertisement impression data. The mobile device impression data identifies manufacturers of corresponding mobile devices and respective device identifiers. At least two unique device identifiers of the impression data correspond to a same mobile device. A total number of unique device identifiers associated with a first manufacturer in the impression data is determined. A de-duplication ratio is accessed based on an identity of the first manufacturer. The de-duplication ratio is applied to the total number of unique device identifiers associated with the first manufacturer to estimate the number of actual mobile devices associated with the manufacturer.
