Identification of Primary Data Sources

To determine which options are not common sources of primary data, we first need to understand what constitutes primary data. Primary data is data that is collected firsthand for a specific research purpose. Common sources of primary data typically include methods such as surveys, interviews, observations, and oral narratives.

1. Tax records data: This is generally considered secondary data because it has been collected and compiled by organizations (e.g., government) for administrative purposes.
2. Oral narratives: This is a common source of primary data, particularly in qualitative research contexts.
3. Surveys: These are a well-established source of primary data as they are conducted specifically for data collection.
4. Observations: This method is also a frequent source of primary data, used particularly in social and behavioral sciences.
5. Census data: While it is collected systematically, it is generally considered secondary data because it is aggregated and analyzed after collection.

Conclusion

Based on the analysis, the sources that are not common for primary data are:

• Tax records data
• Census data
