Methods, apparatus, systems and articles of manufacture to correct attribution errors and coverage bias for digital audio ratings are disclosed. An example method includes applying, by executing an instruction with a processor, a duration-based count matrix to first demographic data associated with collected impressions of digital audio to determine second demographic data, the duration-based count matrix being based on a misattribution adjustment matrix, applying, by executing an instruction with the processor, a coverage adjustment vector to the second demographic data to determine third demographic data, applying, by executing an instruction with the processor, a scaling factor to the third demographic data to determine fourth demographic data, and generating, by executing an instruction with the processor, ratings data at a daypart-level using the fourth demographic data, the ratings data associated with the digital audio.
