But do the statistics support our negative world view or is the world actually improving?

Let's take global population first. It's around 7 billion now, in line with figures predicted by the United Nations in 1958. By the year 2100, the same experts predict it will be around 11 billion. But did you know that 11 billion is probably as high as that number will get? The rate of increase will slow down in the second half of this century thanks to falling birth rates today.   

Falling birth rates? Yes, that's right.

In the last two centuries, improvements in technology and health meant fewer children died young, fueling rapid population growth. These large families produced even more children who survived into adulthood and had their own children. But with the wider availability of contraception in the 1960s, the global average number of babies per woman has declined from six babies per woman to as low as two.

The biggest factor in child mortality is poverty. And while it's still true that only 20 per cent of the world takes about 74 per cent of the world's income, 60 per cent of the world now falls into a middle-income group, with 11.6 per cent – the smallest amount of people in history – still living in conditions of extreme poverty. If the majority of the world's people have money, international aid could realistically achieve the UN target of eradicating poverty by 2030. As poverty goes down, life expectancy goes up, birth rates go down because parents can expect their existing children to survive, and the global population stabilizes.

As for news stories that make us think the world is an increasingly violent place, there is cause for some optimism too. Between the end of World War II and 1990, there were 30 wars that killed more than 100,000 people. Today there are still civil wars, but countries are mostly co-existing more peacefully than in the past. Terrorism has shot up in the last few years and, since World War II, wars have killed many more civilians than soldiers. Even for civilians, though, the statistics are not all bad. Although deaths are nine times more likely to be a result of violent crime than political conflict, the global murder rate fell slightly, from 8 per 100,000 people in 2000 to about 5.3 in 2015.

Of course, none of this means the world is perfect, and whether you personally are affected by war and poverty is often down to the lottery of where you're born. Also, we still face huge problems of our own making, particularly environmental ones like global warming, and wealth and natural resources need to be distributed more fairly. But not all the news is bad news, whatever the TV and newspapers might say.
