Unemployment rate under-estimated

Current unemployment levels could be underestimated by up the 0.5%


Because the source of the unemployment rate is a sample of around 15,000 households which are compulsorily surveyed.

Naturally enough some people refuse to disclose information, can't be contacted, move, etc.To adjust for this the surveyors weight households with similar characteristics to those not responding. To test how effective this is researchers matched March 2013 HLFS with Census 2013 data.

The results suggest that the calibration employed by the HLFS does a reasonable job of adjusting for non-response (once region is included as a benchmark), and that further non-response adjustments have minimal effect on reducing the bias introduced by non-response.

 Using the linked dataset we discovered that bias from non-response exists in the estimates of labour force status from the HLFS. The unemployment rate in the responding sample is underestimated by around 0.3 percent to 0.5 percent, while the labour force participation rate is underestimated by around 0.2 percent. Unemployed people had both the highest non-contact rate and the highest refusal rate. This differs from other studies’ findings, where employed people were found to be harder to contact (Foster, 1998; Stoop, 2005).

So unemployment could be as high as 6.2%

This problem has always existed but appears to be worsening.

Response rates for the HLFS were around 86 percent on average over the four years to 2014, but there has been a downward trend in response rates in recent years that reached an all-time low in the June 2013 quarter (80.8 percent). 

Still, many countries use a form of the HLFS to assess labour force status and will no doubt have similar problems. Arguably comparability and tracking trends is more important than point-in-time accuracy.

Quote of the Day

This sentence leapt out at me from a piece entitled, "Don't be a sucker for socialism" by Glenn Reynolds:

Under capitalism, rich people become powerful. But under socialism, powerful people become rich.

The Moko Rangitoheriri case

Alan Duff savages "Maori violence" and lack of leadership once again.

Back in NZ - and only Auckland - last week it seems as if I never left France.
Except for one major difference, the negative first: a young Maori couple from Taupo convicted of torturing then killing a child under their care. And not one Maori leader stood up and said anything.
Not so young.

As it turns out the male perpetrator - 43 - had been bailed to the address.

CYF has just released a lengthy statement responding to inquiries about the case of Moko Rangitoheriri:

Was CYFS aware David Haerewa was living with Tania Shailer?


Did Probations/Corrections inform CYFS that David Haerewa was being paroled to Tania Shailer's address?

You need to speak to Corrections about this.

If this did not happen - why not - as a result of the inquiries into James Whakaruru's death agencies were meant to share information?

See above

Was CYFS aware of David Haerewa's background?

We did not know David was living with Tania.

If not how could that be the case when Women's Refuge was aware of this?

You need to speak with Women’s Refuge.

So much for joined up government.

I don't blame CYF. I don't blame Corrections. There is so much dysfunction nobody can keep tabs on it all.

And I don't blame Maori leadership either.

But the single-most important point Duff makes is this, quoting Jason Witehira :

Mr Witehira said in his acceptance speech, "It's not about who you are, but what you are. It's about attitude and being an individual and having belief in yourself."
You can bet those hideous child-killer monsters were never exposed to any positive, can-do attitude. No. They grew up on a diet of abuse.
Being a self-believing individual is not particularly compatible with the essentially collective, conformist, Maori culture.

Green dogma disabused

Green MP Jan Logie has jumped on the man-bad/woman-good domestic violence band wagon.

Adding insult to injury, she extends her prejudice to the abuse of children.

At last report, 74,785 children and young people aged under 17 were present at domestic violence police call-out in one year. There is a lot at stake in terms of getting the Government’s response to this right.  Men who abuse their partners are also likely to assault their children.....Internationally the most up to date practice clearly states domestic violence best practice needs to be internalised by the child welfare system. It states there needs to be a specific commitment to partnering with adult survivors and to intervening with perpetrators to enhance child safety. If we don’t do that we put women, children and our society at further risk.
A simple graph will suffice to illustrate how ill-founded Logie's bias is:

The stats are slightly dated but that is because their promulgation is infrequent.

Woman abuse and neglect children too. And when they do, they are neither aberrant nor exceptional examples of female perpetration.

Domestic violence - public attitude can't be railroaded by indoctrinists

In the interests of balance, having been both critical and skeptical earlier last week, I should report that the NZ Herald finally printed a column about family violence that took a differing view from the majority.

The NZ Herald is to be congratulated for its series highlighting NZ's atrocious record of family violence, but there is an inconvenient truth not being spoken, and reinforced by Kyle MacDonald's column Domestic violence is a male problem.
Kyle MacDonald is partly right - but based on the facts, he's also partly wrong. Family violence is not just a male problem. If we as a nation are really serious about reducing family violence, we need to talk about family violence in all its forms and all its causes. The last time I spoke up about this issue was in 2011 and the political response and condemnation was swift.
But I'm more interested in the facts and research and solving the problem than concerns around being politically incorrect.

And Bob McCoskrie goes on to details numerous statistics and research works that support the premise that domestic violence is not just a male issue.

He will be no doubt surprised at the degree of backing he gets from commenters. Almost unanimous.
