The world is richer and healthier

Gloom and doom are in fashion. But, writes Allister Heath, a remarkable collection of economic statistics shows that the reality is much, much cheerier. For all our laments to the contrary, the human race has never had it so good

A remarkable compendium of inform-ation at odds with the present fashionable pessimism, Goklany’s The Improving State of the World, published by the Cato Institute, reveals that, contrary to popular belief, it is the poorest who are enjoying the most dramatic rise in living standards. Refuting a central premise of the modern green movement, it also demonstrates that as countries become richer, they also become cleaner, healthier and more environmentally conscious. 

Needless to say, Goklany has already been accused of naive Panglossianism by the doom and gloom merchants, to whom all must always be for the worst in the worst of all possible worlds. This is deeply unfair to Goklany: like the rest of us, he is concerned at the shameful deprivation, disease and misery that continue to affect hundreds of millions of people in sub-Saharan Africa, North Korea and all the rest of the world’s horror spots. But he argues convincingly that to recognise their horrific plight should not prevent us from also acknowledging our progress in liberating even larger numbers of people from extreme poverty.

We should be especially proud of the fact that humanity has never been better fed: the daily food intake in poor countries has increased by 38 per cent since the 1960s to 2,666 calories per person per day on average. The population of those countries has soared by 83 per cent during that time, so this is a stupendous achievement which puts the final nail in the coffin of Malthusianism.

Together with a 75 per cent decline in global food prices in real terms in the second half of the 20th century, caused by improved agricultural productivity and freer trade, fewer people than ever before are going hungry. The rate of chronic undernourishment in poor countries has halved to 17 per cent, compared with a little over a third 45 years ago. In wealthy countries, the cost of essential foods has collapsed, with the price of flour, bacon and potatoes relative to incomes dropping by between 82 and 92 per cent over the past century; similar trends are now visible in developing countries too.

There is still a long way to go; but never before in human history have so many people been liberated from extreme poverty so quickly. The number of people subsisting on $1 a day has declined from 16 per cent of the world population in the late 1970s to 6 per cent today, while those living on $2 a day dropped from 39 per cent to 18 per cent. In 1820, 84 per cent of the world’s population lived in absolute poverty; today this is down to about a fifth.
