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).

Pedagogical Use Description	This activity is intended for students to conduct a scientific investigation using data. Students will learn and practice the skills of interpreting data and generating graphs. Faculty can incorporate this laboratory activity to teach students how to collect and interpret data. Students would also learn how to use the Logrank (Mantel-Cox) tests to compare the curves of graphs.
