The official Millennium Promise material describes the Millennium Villages Project in the past tense as a 10-year project running from 2005 to 2015. It also says the project operated across 15 sites in 10 sub-Saharan African countries. That directly contradicts the article’s statement that it currently “operates” and that it does so in “more than a dozen African countries.”

So there are two concrete problems here:

1. Timing: the project is described by its own organization as a completed 2005–2015 initiative, not an ongoing one.
2. Geography/count: the official count is 10 countries, not “more than a dozen.”

Project Syndicate’s own current “About” page says its membership includes over 500 media outlets in 156 countries and repeats that it is active in 156 countries. That conflicts with the article’s present-tense claim that it “circulates in 145 countries.”

Because this is a direct, current organizational statistic from Project Syndicate itself, the country count in the article is outdated/incorrect.

Columbia University Press lists The Age of Sustainable Development as a book by Jeffrey D. Sachs with a foreword by Ban Ki-moon. The article’s bibliography entry instead gives the name as “Pan, Ki-mun,” which is incorrect.

So this is not just a stylistic variation: the person’s name is wrong (Ban, not Pan) and the publisher does not list Ban Ki-moon as a coauthor in the way this bibliography entry suggests.

Multiple official biographies for Jeffrey Sachs state that he was born in Detroit, Michigan, in 1954. Oak Park is described elsewhere as the suburb where he was raised, but the birth-place entry in the article gives Oak Park itself as his place of birth.

Because the subject’s own official bio pages consistently identify Detroit as his birthplace, the infobox entry listing Oak Park, Michigan, U.S. is incorrect.
