  1. Defining Demography Monday, August 25

  2. What is Demography? • “…the study of the size, territorial distribution, and composition of population, changes therein, and the components of such changes.” (Hauser and Duncan 1959, p. 2) • “Discipline, interdiscipline, subdiscipline” (McFalls, Jr. 2003)

  3. Births, Deaths, Migration, +++ PAA 2009 Call for Papers

  4. Four Facets of the Field(Crimmins 1993) • How and Where Demography is Done • Changes in information processing • Larger amounts of data • More sophisticated methods • Less centralization • More multi-investigator research • Demographic centers that operate like natural scientists’ laboratories • Trend towards specialization

  5. NICHD Funded Population Centers • R21 (5) • UC-Boulder, UC-Berkeley, Fenway Inst, Ohio State, Northwestern • R24 (19) • RAND, BGSU, Brown, UCLA, Chicago, Johns Hopkins, SUNY-Albany, Maryland, Michigan, Minnesota, UNC, Penn, Penn State, PRB, Princeton, UT-Austin, Washington, Wisconsin

  6. Four Facets of the Field(Crimmins 1993) 2. The Data of Demography • From aggregate to individual level foci • Large-scale sample survey boom • Longitudinal surveys • Multiple cohort longitudinal studies • Revisiting social contexts

  7. Formal Demography Mathematically based Consistent approach Life tables Observation and description focused Some change in the data being used Questions broadened Social Demography Causal models Analyses have changed with methodological and data innovations Four Facets of the Field(Crimmins 1993) 3. The Methods Employed

  8. Theoretical Approaches(Crimmins 1993) • Scope of the field has widened • Theory, especially for explanation, more common • “Theoretical developments have been the engine pulling the field of demography, while computers may have provided the fuel.” (p. 587)

  9. Demographic Contributions(Xie 2000) • Providing “statistical facts” • Forecasting future states of human societies • Age, period, cohort thinking • Life course approach • Statistical advances • Biological approaches

  10. Discussion • What did you learn about the field of demography in today’s readings and/or class discussion? • What are your demographic interests?
