  1. Sources of Data Wednesday, August 27

  2. Primary vs. Secondary Data

  3. Data Collection Instruments • Census • Vital Statistics • Population Registers • Surveys • Historical/Archival Records • Less Structured Interview/Observation Methods

  4. Census • Complete enumeration • Counting focus • De Jure vs. de facto • Regular intervals • Canvasser vs. self-enumeration • U.S. Census 1790-2000…

  5. Vital Statistics • Recording of events (births, deaths, marriages, etc.) • Usually on certificates • Sometimes combined with census data

  6. Population Registers • A system to keep track of all residents of a country (but can be partial) • Continuous reporting • Each person has an ID number • Privacy issues • Easiest in countries with small and literate populations

  7. Surveys • Usually involve sampling • Covers more topics/usually longer • International Surveys • U.S. Government Surveys • Research Surveys

  8. Historical/Archival Records • Civil or church records from back in time • Family reconstitution • Skeletal evidence • History calendars (hybrid method)

  9. Less Structured Interview/Observational Methods • Are more inductive • Allow for new insights to emerge • Can be the sole method for investigation, or can combine with other methods

  10. Anthropological Demography • What is it? • What does it contribute to demography?
