In the social sciences, a survey refers to standardized, quantitative overview studies that provides information on specific groups or observational units, such as households, family structures, age groups (youth, retirees, workers, etc.), or individual companies and organizations. Survey data are usually collected through questionnaires or structured interviews. These data represent statistical microdata, allowing for the investigation of relationships and characteristics at the individual level. Surveys are standard methods in quantitative social research and are also employed in social and cultural anthropology to gather general information on social parameters, such as household compositions, economic conditions, or age structures within a population.
