This is a deviation from AP Style.
Do not use the terms developing world, emerging economy or Global South to describe any country or region. Instead, include economic data relevant to a story’s news value.
The terms are geographically imprecise, do not have widely-accepted definitions and are generally used as sanitized synonyms for poverty. Using generalized terms to imply poverty across large land areas and countries that have little else in common reflects bias and defines complex communities by foreign standards of wealth.
