Primary Data Collection
Primary data is directly generated by the researcher. Household surveys are the prototypical example of primary data collection. Unlike Secondary Data Sources, primary data collection can be personally directed by the researcher to ensure it meets the standards of quality, availability, statistical power, and sampling required for a particular research inquiry. With globally increasing access to survey tools such as software, field manuals, and specialized firms, data collected and owned by the researcher has become the dominant method of empirical inquiry in development economics.
Types of primary data
The most common types of primary data are personal interviews. Depending on the research, these may take the form of household surveys, business (firm) surveys, or agricultural (farm) surveys.
Modes of primary data collection
Surveys can be conducted on paper (Pen-and-Paper Personal Interviews (PAPI)) or electronically (Computer-Assisted Personal Interviews (CAPI)), or a combination of the two (Computer-Assisted Field Entry (CAFE)).
