About Elections Modelling
What it is
These pages are the output of a program that simulates a electoral systems. It can accomodate models that have ridings with 1 or more MPs and regions with 0 or more "top-up" seats assigned to clusters of ridings. That is, it can model:
- First-Past-The-Post: 1 MP in each riding, no top-up seats
- Alternative Vote: 1 MP in each riding, no top-up seats
- Mixed Member Proportional: 1 MP in each riding with top-up seats
- Single Transferable Vote: multiple MPs in each riding, no top-up seats
- Hybrid models: 1 or more MPs in each riding with top-up seats.
How it works
The overall model is:
- Group existing ridings into new ridings, each with an assigned district magnitude (which may be as low as 1). An existing riding may be split between new ridings.
- Group the new ridings into compensation regions, giving each a number of compensatory or "top-up" seats (which may be as low as 0).
- Run an election in each of the ridings to determine the riding MPs. Several different election algorithms are implemented.
- For each region, determine which parties should be assigned the top-up seats.
