Demography from physical cemeteries, "virtual cemeteries," and census data

Thumbnail
In this exercise, students will use data concerning lifespan and demography to generate graphs, compare the survivorship curves of two cohort groups with Logrank (Mantel-Cox) tests, and explain the differences in the curves.

Students collect, interpret, graph, analyze, and present data on the demography of human survivorship using the data from tombstones in local cemeteries that provide ages at death, on-line cemetery records, and census records that provide the numbers of people alive in different age classes.

This activity is included in Volume 8 of Teaching Issues and Experiments in Ecology (TIEE).
