Don't let on, but property crime is down

Wow. Did you see the latest figures for the falling crime rate? Pretty good, eh? What's that, you didn't see the figures? No one told you, eh.

It's true. Despite the best efforts of the federal Minister for Justice, Jason Clare, on Sunday, the Australian Institute of Criminology's latest compilation of statistics got remarkably little attention.

Why? One reason could be that it's old news. Levels of property crime have been falling for a decade. You've long known that, right? If you have, congratulations: you're much better informed than most.

A survey conducted in NSW in 2007 found that more than 80 per cent of respondents believed property crime had been increasing or had remained stable over the past five years. Only 11 per cent said it had been falling.

So why were the media so uninterested? Because they didn't think you'd be interested. They presumed you'd prefer to have your existing beliefs reinforced rather than up-ended. But I prefer to write for the minority who want to be informed rather than humoured.

The figures show falls in all the main categories of recorded property crime - burglary, motor vehicle theft and "other theft" (pickpocketing, bag snatching and shoplifting) - across Australia in 2010.

They also show falls in all the main categories of recorded violent crime - homicide, assault, sexual assault and robbery - other than kidnapping/abduction in 2010. For the latter, the number of cases rose by 39 to 603.

But levels of crime can rise or fall from one year to the next without that proving much. What really matters is whether the longer-run trend is up or down.

The clearest evidence is of a long-run decline in recorded property crime. The number of burglaries reached a national peak of almost 440,000 in 2000, and has since halved to fewer than 220,000 a year.

The number of motor vehicle thefts reached a peak of 140,000 a year in 2001, and has now fallen by 61 per cent to below 55,000 a year. Other thefts peaked at 700,000 a year in 2001, but are now down by a third to almost 460,000 a year.

If you allow for our rising population - up by a per cent or so a year - the decline in the rate of property crime is even greater.

So, as I say, it's clear property crime has been declining for a decade. For violent crime the trend isn't as clear - except for robbery, the property crime with violence. Robberies reached a peak of almost 27,000 in 2001, but have since fallen by 44 per cent to below 15,000 a year.

It's hard to detect any trend in the level of kidnapping and abduction, though the rate is very low: 2.7 incidents per 100,000 population. You wouldn't expect to see a trend in homicide, the rate of which is also very low: 1.2 incidents per 100,000 population. But after being well above 300 a year until 2006, it's been below 300 a year since then.

No trend in the number of assaults is visible to the naked eye, but the rate of assault seemed to peak in 2007 at 840 victims per 100,000, and is now down to 770 per 100,000. If this trend is confirmed, it will be because police have begun targeting the worst-offending licensed premises.

It's estimated only about half of all sexual assaults are reported to police. The number of recorded sexual assaults rose markedly between 1996 and 2008 to 20,000 victims a year - perhaps because of growing willingness to report offences - but though the arithmetic says the rate of sexual assault has been falling modestly since 2006, I'm not sure I believe it.

So why has property crime been falling? When the decline was first observed in the early noughties, much of it was attributed to a shortage of heroin, which led to a decline in its use and, hence, a fall in thefts by heroin addicts.

That seems true enough, but though heroin prices and purity stabilised in about 2004, the fall in property crime continued. Obviously, there must be more to it.

Most criminologists believe the amount of property crime is linked to the state of the economy. Unemployment has fallen and average weekly earnings have risen in real terms since the start of the noughties, so this may well help explain why people have been less inclined to take stuff that doesn't belong to them.

Another part of the explanation for which there's solid evidence is an increase in the proportion of property offenders who are imprisoned. The story here is not so much that tougher sentences are a greater deterrent, but that the more time you spend behind bars, the less time you're able to practise your nefarious profession.

And there are other possible explanations which, though untested by researchers, seem plausible. One is increased police effectiveness. They've been pushing hard on repeat offenders and also shifting their resources to crime hot spots at "hot" times of the day or night. Their crackdown on pubs and clubs with the worst records of assaults is a case in point.

A further possibility is that success breeds success. The more the incidence of crime falls while the number of coppers remains stable or rises, the easier it ought to be to catch offenders. As for motor vehicle theft, it's likely improvements have made cars harder to pinch than they used to be.

I finish with an appeal: you may prefer to know the truth, but keep it to yourself. Please don't spoil the fun of those who like to imagine they could be swept away at any moment by the rising tide of crime.
