The course provides the basic concepts and tools for the analysis of the demographic structure of populations and their behaviours: social and demographic sources of data, measure of mortality, fertility, nuptiality, migration; population growth issues, population projection.
Concepts and measures will be verified using real data and examples obtained from the administrative and survey data sources.
The course concludes with some reflections on the history of the world's population.
Students can choose among the various books on Demography available, for example:
- S.H Preston, P. Heuveline, M. Guillot, (2001) Demography – Measuring and Modeling Population Processes, Backwell Publishing
- G. De Santis (2010) Demografia, Il Mulino, Bologna.
- M. Livi Bacci (1999) Introduzione alla demografia, Loescher Editore (available in the library)
- A. Santini - Appunti di Analisi Demografica (downloadable from Moodle)
- M. Livi Bacci (2016) Storia minima della popolazione del mondo, Il Mulino, Bologna. (5^ ed; 1^ ed. 1998)
To provide the student with the bases for understanding and measuring population processes, as well as the knowledge of the characteristics and evolution of demographic aggregates, in particular:
a) understand demographic dynamics (interplay of stock and flow data);
b) know where to retrieve demographic information
c) be capable of calculating autonomously the main demographic indicators, cross-sectionally and longitudinally, given the proper raw numbers
d) understand demographic problems; envisaging possible solutions.
Preparatory teaching: Statistics I
