What percent of people in the world drink coffee?

It's impossible to give an exact percentage of people who drink coffee worldwide. Here's why:

* Data limitations: Gathering accurate global consumption data is incredibly difficult. Many factors contribute to this, including:

* Lack of reliable data collection in some regions: Especially in developing countries, comprehensive data on coffee consumption may not be available.

* Variations in definition: What constitutes a "coffee drinker" can vary. Does it include decaf, instant coffee, or only brewed coffee?

* Constantly changing patterns: Consumption trends are dynamic. Coffee consumption is rising in some parts of the world, while it might be stable or even decreasing in others.

However, we can look at estimates:

* A 2020 report by the International Coffee Organization estimated that 2.25 billion cups of coffee are consumed daily worldwide. This number gives a sense of scale, but doesn't directly translate to a percentage of the global population.

* Various studies suggest that coffee consumption is highest in Europe and North America, followed by Asia and Oceania.

Therefore, while we cannot pinpoint an exact percentage, we can confidently say that coffee consumption is widespread and a significant part of global beverage culture.
