The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited environment, and where only one sex, usually the female, is considered.

What is a generalization of the Leslie matrix?
A generalization of the Leslie matrix occurs when the population is classified due to development stages instead of age classes (Lefkovitch matrices). In this scenario, an individual may reproduce, die, grow from one stage to another, or stay in the same stage.

What are the survival probabilities in the Leslie matrix?
The survival probabilities, Sx, are given in the sub-diagonal; S 1 through S 3 are survival probabilities from one age to the next. For example, S 1 is the probability of individuals surviving from age 1 to age 2. All other entries in the Leslie matrix are 0.

How does a Leslie model work?
In a Leslie model, the population is divided into groups based on age classes. At each time step, the population is represented by a vector with an element for each age class where each element indicates the number of individuals currently in that class.

What is a positive dominant eigenvalue in Leslie matrices?
If at time step t = 100, our population has reached it’s long term growth rate and the population is 1000, then at time step t = 101, the population will be 2000, and so on. ◮ This means that our population is growing by 100% in each time step. ◮ Leslie matrices ALWAYS have exactly one positive dominant eigenvalue.

What is the difference between a Markov chain and a Leslie model?
The Leslie model is very similar to a discrete-time Markov chain. The main difference is that in a Markov model, one would have for each , while the Leslie model may have these sums greater or less than 1. This age-structured growth model suggests a steady-state, or stable, age-structure and growth rate.
