Music video producers use various research methods to define their target audience, including quantitative, qualitative, socio-economic status, demographics, psychographics, and geo-demographics research. Quantitative research uses surveys and statistics to gather numeric audience information on a large scale, while qualitative research uses interviews and focus groups for detailed feedback. Demographics and psychographics provide comprehensive yet detailed information about audience characteristics and behaviors. Geo-demographics research helps determine where a music video will be most commercially successful based on economic factors. Producers then use this audience research to determine the size of their target audience.
