Like songs, the best graphs tell stories. Here are my 10 favourites from 2021

“One of the first things you have to decide on with a musical is why should there be songs.”
The person speaking is Stephen Sondheim, the writer of some of the best songs for musicals in the 20th century, who died in November aged 91.
You can put songs in any story, but what I think you have to look for is, why are songs necessary to this story? If it’s unnecessary, then the show generally turns out to be not very good.
I’m no Sondheim, but as an editor I won’t put a graph into any story unless it is absolutely necessary to tell the story.
When I do, the picture can be worth at least the 800 words that accompany it.
So here are my 10 favourites from the business and economy stories I edited for The Conversation in 2021.
Some of the best graphs remove doubt
This graph, from the Bureau of Statistics, leaves no doubt about what happens to consumer spending when lockdowns end.
Released in November, with the national accounts, it uses bank account data to show what happened to spending on clothes, furnishings, recreation, transport and restaurants and hotels.

While the effect is clear, and beautifully illustrated, it can be interpreted in two ways. One is that lockdowns are to be avoided because they suppress ordinary life.
The other is that Victoria’s long lockdown was caused by the failure of the NSW government to lockdown quickly enough and hard enough as the Delta variant spread, meaning lockdowns are to be embraced, and quickly.
Another graph that removed doubt is this one showing what Australia’s July 2012 to July 2014 carbon price did to greenhouse gas emissions, excluding those related to land use and forestry that are subject to government directives.

Whatever else is said about the carbon price, its effect on emissions is clear.
Also clear, and enormous when you look at it, is what our current system of adjusting JobSeeker only in line with the consumer price index will do to it compared to the age pension, which is adjusted in line with wages.
The projections in this graph derive from the mid-year intergenerational report which looks forward 40 years.
After 40 years – unless there’s an extra increase, and one wasn’t allowed for in the intergenerational report – JobSeeker will be a mere fraction of the pension.

Also shrinking, with unfortunate consequences for Australians with mortgages and Australians trying to get them, has been wage growth.
The government has been forecasting a return to the 3-4% wage growth we once had in every budget since 2012, save for the last two.
Right now public sector wages growth, which used to lead private sector growth, is well below 2%. Private sector growth has started to climb, but it is well short of where it was.

Up until the year 2000, buying a home cost between two and three times household after tax-income.
Then, after the headline rate of capital gains tax was halved and investors dived into the market, prices climbed to between three and four times income.
Six years ago they jumped again to between four and five times income, and in 2021 they climbed once again to more than six times disposable income.

While low wage growth should make it harder to pay off a loan than it used to be, just at the moment ultra-low interest rates are making it easier to service mortgages than it has been in decades.
But what the Reserve Bank calls housing accessibility (to distinguish it from housing affordability) is much worse.
Astounding price growth and a decade of weak wages growth have pushed up the cost of an average first home deposit from 70% of income to more than 80%.

Other graphs surprise
If we start building more houses, it stands to reason that we will get more houses.
That’ll doubtless be the case eventually, but if you are expecting it to happen any time soon, you will be disappointed.
In the space of a year, the number of Australian houses (not apartments) under construction has jumped from 56,060 to 88,445 — the most ever.
But bizarrely, as has been the case for half a century, the number of houses completed each quarter has barely moved.
It’s as if homebuilding can’t scale up.
