Aims and objectives

Aims

To introduce the concept of reproductivity and associated measures of generation length and growth and how they are affected by age-specific fertility and mortality.

Objectives

By the end of this session you will be able to:

• Calculate the Gross Reproduction Rate (GRR) and the Net Reproduction Rate (NRR)
• Predict the influence of varying age-specific mortality and fertility schedules on the NRR
• Define the concept of generation length
• Understand the difference between the mean age at childbearing in a cohort and in a real (growing) population
• Explain the relationship between the NRR, growth rate and generation length
• Describe how the NRR, growth rate and generation length might differ if calculated using male rather than female data

This session will take approximately 2.5 hours to complete.
