Naïve about leave

Since my maternity leave has officially started, I am indulging in some TV catch-up, and today that included watching the season finale of American Idol. I got a little confused as the line-up made me think I was stuck somewhere between the ages of 10 and 16 – every act conjured up childhood memories*.

This being the first day of my maternity leave, it has been spent milling about for the most part. In Norway, maternity leave starts 3 weeks prior to your expected due date. Parents have the choice of taking either 46 weeks at 100% of pre-leave salary or 56 weeks at 80% salary. You can read more about maternity leave benefits in Norway here.

Daddies aren’t left out either. As of July 1, 2009, men can take up to 10 weeks in paternal leave permission (this comes out of the 46 or 56 total week allotment).  Dad even gets an additional two paid weeks of omsorgspermisjon to help mom get back on her feet immediately after birth. Basically, fathers in Norway get more fully paid maternity leave than mothers in the US or UK. You can read a little more about paternity leave in Norway here.

Why is the leave allowance so long here in Norway and so comparatively short in other places? On the one hand, it would be super to say it is because of the value placed on the family unit in countries like Norway. Unfortunately, that would be both naïve and incorrect. Have a look at this map:

The maroon area represents countries with at least 18 weeks of paid maternity leave.

What do the majority of those countries have in common?

If you guessed that their politics were historically rooted in either socialist or communist** regimes, you’d be right.

But even more fundamental than this histo-political information is why it matters. In a nutshell, birth rates tend to decline over time in strong communist or socialist regimes. When birth rates decline, there are less people to pay tax into the communal pot that will then be returned to the population in the form of social benefits. Basically, if there aren’t any new taxpayers being born, the whole system will collapse.

So countries like Norway recognized this negative birth rate*** and had to come up with a plan to get people back in the bedroom to produce the next generation of taxpayers. Ask any Norwegian who has adult children and they will scoff at how long parental leave is now – it wasn’t always that way. Ask someone with older children and they, too, can remember their own leave even in the last decade not being as long as current mandates. But to get people to have more kids, the government provides extra incentives such as longer parental leave rates, subsidized barnehage (day care), child benefit payments, and extra financial support if you are a single parent.

Does this level of social benefit for procreation’s sake leave recipients with a sense of disproportionate entitlement when it comes to other benefits? Kanskje. But that’s for another post.  I have to go see who won American Idol.  Not to worry, though – I have 46 weeks to ponder this.

Give it up

The New York Times published an article last week about the ‘growing trend’ of Americans renouncing US citizenship. But in true sensationalist style, it was over-reporting on an underwhelming issue.

The article states that 743 expatriates renounced US citizenship last year. This would be remarkable if it didn’t comprise less than 0.01% of the 5.2 million Americans living abroad. Not one percent. Not even one-tenth of one percent. One-one hundredth of one percent. In fact, these 743 folks represent a mere 0.0002% of the total population of approximately 309 million American citizens. Based on those figures, I'm not sure I would call this spate of renunciations an epidemic.

I have to assume it was a slow news day.

What’s even more disappointing is that it wasn't just over-reporting - it was actually re-reporting. Virtually the same article was written by another NY Times journo back in 2006. Like, really… the same article. I would write my freshman level college students up for lack of originality had they pulled a stunt like this. I get that sometimes you have to recycle a story, but, come on… the same anonymous Swiss resident business executive and leader of a political interest group were the only two sources each NYT journo could find over a two and a half year stretch?

I’m all for a little hyperbolic reporting (heck, I get most of my news from Perez Hilton and the Daily Mail, so I don’t judge), but at least make it significant. And, for the love of Pete, make it original.

We're number one! ...or are we?

All my Norway Facebook friends are posting, reposting and cross-posting. Big news in these parts, the UN has announced Norway is the best country in which to live.

Husband originally called to tell me this. What I thought he said was "Hey! Norway is now the best place to live. The UN posted a poll on Facebook!" He let me rant on about shoddy data collection methods for a wee while before he corrected me. What he actually said was "I posted it on Facebook!" I really should listen to Husband a little better.

In any event, just because the results weren't collected by a Facebook poll, as a student of statistics and research methods, I still do think it's worth considering the methodology of the poll. I'm not here to comment so much on the results of the survey, but rather to really understand how Norway got to number one.

The Human Development Index (HDI) provides "a broadened prism for viewing human progress and the complex relationship between income and well-being." However, there are some important limitations of the index, namely that it does not include any factors related to gender or income equality, political freedom, or human rights (of course some clever souls have created separate indices for those).

It's worth noting that this is not actually news. Norway has held the number one spot every year since the HDI was initiated in 1980 (see page 167 of the full report*). It's also worth noting that Norway did not win the top spot by a landslide. Norway's 2009 HDI was 0.971, whereas the number 2 and 3 spots were taken by Australia and Iceland with scores of 0.970 and 0.969 respectively.

The methodology of the HDI has also changed. The report authors mention this on page 170, noting that "The human development index values in this table were calculated using a consistent methodology and data series. They are not strictly comparable with those published in earlier Human Development Reports." If it's consistent, then it should also be comparable. A fundamental measure of 'good' research is that it is reliable, which means that the same tests can be repeated using the same instruments. To change these instruments mid-stream calls into question the statistical constructs and comparability of the annual reports.

One of the reasons the underlying tests that comprise the HDI have changed is because the focus of the report has shifted. As of 2009, the report focuses on migration and opportunities available to immigrants in more developed countries. So the report is not necessarily measuring the best place to live, but rather the best place in which to live if you are in one of the less-developed countries looking for a new home that will afford you a longer life expectancy, easier access to education, and more economic opportunity. The HDI is not a measure of where you can find the best healthcare, school systems, and jobs (assuming these are measures of a good place in which to reside). It's more a measure of how to find better versions of those things based on where you originally come from.

So is Norway really the best place to live? Perhaps. But UN statisticians can't decide that - it's up to each of us to find our own best place. And you probably don't even need statistics to do it.
