2
Q

A
population growth and decline
3
Q
What are life tables?
A
help us summarise survival and reproductive rates in different age groups based on a single cohort
4
Q
What do life tables require?
A
Long term study of population with marked individuals
5
Q

A
Graphical representation of survivorship data from life table
6
