Abstract

As the title to this chapter suggests, demographers adopt either (or both) of two perspectives, or approaches, in analysing demographic data. They are the cohort approach to demographic analysis and the period approach to demographic analysis. The difference between these two approaches is most readily understood by making use of a graphical device known as the Lexis diagram. Named for Wilhelm Lexis (1837–1914), a German statistician, actuary and economist who was the first to use it, the Lexis diagram is also an invaluable tool for conceptualizing the construction of demographic measures and the procedures followed in demographic estimation and projection. The first part of this chapter is devoted to describing it and the concepts on which its use rests.
