Global deaths from cancer have increased, but the world has made progress against it— Over the past four decades, the global number of people dying from cancer each year has doubled. This can look like the world is losing its battle with cancer: people are more likely to develop it, and we’re getting no better at treating it. This isn’t true. There are, of course, almost 4 billion more people in the world than in 1980. And many of those people are older. This matters a lot because cancer rates rise steeply with age. The chart shows three different measures: Total deaths just count how many people died from cancer; this is the number that has doubled and is shown in red in the chart. Crude death rates, shown in brown, adjust for population size; the increase shrinks from more than 100% (a doubling) to around 20%. Age-adjusted rates, shown in blue, also account for the fact that countries have older populations today; we can see that the fully age-adjusted rate has actually *fallen* by more than 20%. This means that for the average person, the likelihood of dying from cancer in any given year is now *lower* than it was for someone of a similar age in the past. The world still has a long way to go in preventing and treating cancer, but it’s wrong to think that no progress has been made. (This Data Insight was written by @_HannahRitchie.)
