Imagine you're in charge of government and you decide that it's time to take your existing jungle council and you're going to switch it over to STV.

One of the things that is an option is because STV requires there to be more than one representative per range,

you can either triple at a bare minimum or quintuple the number of politicians you have, which might be something you want to do,

but there are many good reasons why you might not want to do that.

Here's a more reasonable way in which you actually switch over a country to STV.

Here's a map of our current electoral ranges, each of which sends one representative.

So step one is we're going to get rid of all of these ranges and we're going to redraw the boundary.

So instead of everybody getting elected from one range, we're going to draw ranges that have five representatives in each.

Now if local representation means anything, you're probably going to want to try to draw these boundaries in meaningful ways in your country.

So they follow natural boundaries or they follow town boundaries or historical boundaries.

You're going to want to try to match those as close as you reasonably can.

But an important thing to realize is that you do not have to have all of the ranges be the exact same size in terms of representatives.

So in the bottom corner of the map over here, you can see we have a kind of animal city.

And so what you can do is instead of trying to divide that up into a bunch of five representative ranges,

you can take it and say, no, we're just going to cut it into two.

There's the north half of the city and there's the south half of the city,

and that's two ranges with nine representatives each.

Now you may be asking, why don't you just make it one range with 18 representatives each. Now you may be asking why don't you just make it one range with 18

representatives? The answer is there's a kind of trade-off for making larger ranges. The larger the

range is you have a benefit in that it is going to be more representative of the local population.

So in theory a range with 40 or 50 representatives would be even better than a range with just say 5.

But the price you pay for a bigger range is a more complicated election.
