Top income brackets in marginal seats

All seats held by either side with margins of five percent or less.

Ranked by number of electors in the top tax bracket. Five percent could be called marginal. There are 39 of these in all.

On each line is the seat name, state, current margin, AEC Geographic category, the number of high income numbers and (national rank out of 150).

Does this mini-table tell us much?

Kalgoorlie's a surprise list-topper, with the rest of the top dominated by urban seats. Clicking Kalgoorlie shows a median income ranking of 38, much further down the scale than 10, its ranking in this list. Kalgoorlie has a high Aboriginal population.

Ranking-wise, it's a little bottom heavy, with 18 seats in the top 75 (that is, with a 75 or lower in the (brackets), and 21 below. The ones below 75 are on average more marginal. And the average rank for this lot is 84, which means it is over-represented by seats with lower numbers of top income earners.

There's also an unsurprising urban/non-urban split, with city seats predominating in the top.

There's just one seat (Kalgoorlie) in the top ten, and five in the bottom ten. There are three in the top 20 and nine in the bottom twenty. And so on.

Conclusion: any inherent desirability aside, cutting top rates would deliver poor electoral bang for the buck. It's probably a pitch to the relatively affluent outer suburbs of Sydney and Melbourne.

But in reality, the regions are where the action will be - or should be, if the ALP is to have a chance. And there are few people on top dollars there.
