The World 99 Percent

By Taylor Marvin

Here’s an interesting graphic that’s been making the rounds on We Are the 99 Percent tumblr:

Is this true? Is the income of the bottom 99% of US citizens in the top 1% of world income?

Short answer: maybe. From the World Bank, World Development Indicators dataset, in 2009 per capita US income was $45,989, compared to a world average of $8,599. Plugging this into the Global Rich List income comparison tool tell us that the average American falls into the top 1.43% of humanity, suggesting that the 99 Percent graphic’s claim is just off. However, there are a lot of problems with this comparison. For example, the average US income provided by the World Bank is given in GDP per capita. This is problematic for a few reasons. First, it includes the income of the top 1%, which we’re not interested in and in the US is high enough to significantly skew this figure. Similarly, GDP per capita is an averaged measure — while this is often the best income measure economists can get, it doesn’t account for inequality. Is there a better estimate? It’s hard to tell. This morning Washington Post columnist Suzy Khimm reported that in 2010 US households in the bottom 60% earned $59,154, while those in the bottom 20% $33,870. Remember, these are household earnings — suggesting that the average earnings from the bottom 99% of individuals is significantly below the GDP-derived $45,989 figure. However, since this conjecture lowers our expected 99% average income it suggests that the average 99% American even farther below the world top 1%.

However, there’s another problem. We aren’t just interested at looking at inequality within a country, but across the world population. GDP per capita in dollars is a bad measure for this, because we aren’t really interested in strictly income, but rather how much consumption that income buys. Because prices of goods vary widely across countries, it’s more accurate to use Purchasing Power Parity (PPP) — the value of local goods purchasable with the average national income — as a measure of comparing income. The difference between GDP per capita in nominal dollars and PPP isn’t always predictable — for example, Japanese per capita income is roughly constant for both GDP per capita in current US$ and GDP based on PPP per capita GDP, while both Lebanon and Jamaica’s average income plummets when looking at income based on PPP per capita GDP. In the United States however, income goes up when we consider purchasing power: rising to $55,622 when measured in PPP. This makes the average American better off compared to the rest of the world, indicating that the average income for the bottom 99% in the USĀ may fall into the world’s top 1% in terms of consumption if not nominal income — unfortunately it’s difficult to be more precise.

But that doesn’t change the core issue here: on average Americans are much, much better off than nearly all of the rest of the world, and We Are the 99 Percent is right to stress that point. However, implying that famine and extreme poverty is the norm for 99% of humanity is misleading. I’m not arguing that famine and extreme poverty doesn’t exist — as of 2008, one in four residents of the developing world lives on less than $1.25 a day. However, in the last quarter century humanity has made enormous progress combating poverty, and the extreme poverty We Are the 99 Percent highlights is increasingly far from the global norm.

In 2008 1.4 billion people lived in extreme poverty, compared to 1.8 in 1990. When considering the large human population growth of the last twenty years this achievement becomes much more remarkable. Incidence of famines are down drastically, and the developing world is mostly on track to halve 1990 poverty levels by 2015. Again, this isn’t to say that extreme poverty isn’t a pervasive problem — it is, and the degradation and pain of extreme poverty is a continuing horror. However, there are good reasons to be optimistic about the future.

World regional incomes spent most of the last 500 years rapidly diverging, with Europe and select European post-colonial states rapidly becoming much richer than their peers. However, in the last half century world income across regions have begun to converge, with the rest of the world beginning to ‘catch up’ to the historically richer West:

There’s still a large difference between incomes in the developed and developing worlds. However, if current trends hold this gap is likely to shrink through this century. This projection becomes even more encouraging when considering the size of the regions highlighted in this graph:

15% of the world’s population live in advanced economies, a fact that often under appreciated in the public consciousness. Moreover, an increasing percentage of advanced economies only recently achieved high-income status. The newly industrialize Asian economies, some of the richest in the world, only matured within the last three decades, unlike the Western European ex-colonial powers that dominated the global economy for centuries.

What’s especially encouraging is that despite the global collapse of 2008 most regional growth trajectories remain fairly robust. This is especially evident in developing economies — while Euro Area and US growth will likely remain anemic throughout the decade, growth rates in developing economies, rather than the developed world, will increasingly determine the course of the global economy. Developing Asia is an especially important part of this trend. Because the region is home to nearly half of humanity, positive developments there have an enormously important impact on the fortunes of humanity in general. Strong growth rates in China and India are an hugely important gain for humanity. This century Americans will increasingly fall out of the world’s top 1%, and in the global aggregate that’s a good thing.

However, despite the ongoing aggregate global convergence, select regions are being left behind. This is extremely worrying. The We Are the 99 Percent graphic highlights famine in Africa as the human norm — while this is increasingly incorrect in a global context, it remains depressingly common in Sub-Saharan Africa, where growth rates are projected to remain low into the foreseeable future. As the rest of humanity becomes richer and increasingly convergent on a global scale, we should become increasingly worried about the bottom 20% that’s being left behind.
