For the first time since agriculture-based civilization began 10,000 years ago, the majority of humankind is no longer poor or vulnerable to falling into poverty. By our calculations, as of this month, just over 50 percent of the world’s population, or some 3.8 billion people, live in households with enough discretionary expenditure to be considered “middle class” or “rich.” About the same number of people are living in households that are poor or vulnerable to poverty. So September 2018 marks a global tipping point. After this, for the first time ever, the poor and vulnerable will no longer be a majority in the world. Barring some unfortunate global economic setback, this marks the start of a new era of a middle-class majority.
We make these claims based on a classification of households into those in extreme poverty (households spending below $1.90 per person per day) and those in the middle class (households spending $11-110 per day per person in 2011 purchasing power parity, or PPP). Two other groups round out our classification: vulnerable households fall between those in poverty and the middle class; and those who are at the top of the distribution who are classified as “rich.”
The consequences could be interesting:
Why does it matter that a middle-class tipping point has been reached and that the middle class is the most rapidly growing segment of the global income distribution? Because the middle class drive demand in the global economy and because the middle class are far more demanding of their governments…
In most countries, there is a clear relationship between the fate of the middle class and the happiness of the population. According to the Gallup World Poll, new entrants into the middle class are noticeably happier than those stuck in poverty or in vulnerable households. Conversely, individuals in countries where the middle class is shrinking report greater degrees of personal stress. The middle class also puts pressure on governments to perform better. They look to their governments to provide affordable housing, education, and universal health care. They rely on public safety nets to help them in sickness, unemployment or old age. But they resist efforts of governments to impose taxes to pay the bills. This complicates the politics of middle-class societies, so they range from autocratic to liberal democracies. Many advanced and middle-income countries today are struggling to find a set of politics that can satisfy a broad middle-class majority.
There are multiple issues to consider here: how all of this is measured, whether the majority is relatively evenly spread across countries or is concentrated in certain areas, and what this might bring.
But, I will point to another feature of this study: it suggests relatively good news. For much of human history, larger-scale collectives – from kingdoms to empires to countries – have consisted of some elites, perhaps a limited middle class, and a larger poor and working-class population. If these figures are true, more people have access to resources and opportunities to do things.
This would fit nicely with some materials I have heard in recent years about a good amount of good news about the global system. On one hand, there are still major problems and sizable poor and vulnerable populations (the less well-off half in this study). On the other hand, global health is improving, economic conditions on the whole are improving, violence is down (in relative terms), and people around the world may be paying attention to the plight of others like never before.
Perhaps this is why even Google has ways of providing some of good news. Even if much news revolves around problems, there is plenty of good news to find.
