Carly Fiorina: 70% of world's poor are women

Editors note: After this fact-check published, we looked deeper into the stat Fiorina cited. You can read that work here.

It is a powerful statistic that speaks to a fundamental injustice in this world. It emerged nearly two decades ago and has been used as a call to action ever since.

Over the weekend, former Hewlett-Packard CEO Carly Fiorina repeated it on ABC’s This Week.

"Seventy percent of the people living in abject poverty are women," Fiorina said.

But so far as anyone can tell, that statement has no basis in fact.

We reached out to Fiorina’s office and asked for the supporting data. We did not hear back.

We went to the World Bank data pages and contacted the bank’s research staff. We exchanged emails with the United Nations Development Programme, and UN Women, an entity focused on gender equality. None of them could point to statistics that would confirm this claim.

"I checked with our research colleagues, and we can indeed not verify this figure either," said Nanette Braun, chief of communications and advocacy at UN Women headquarters.

It’s a telling admission, given that UN Women references the statistic on its own Web page.

Duncan Green, who spent eight years as director of research for Oxfam-Great Britain, the international poverty relief organization, flagged a problem with the statistic three years ago in a blog post on Oxfam’s website. Green is now Oxfam’s special strategic adviser.

"Every expert (feminist economists, poverty researchers etc.) I’ve consulted on this agrees the number is dodgy," Green wrote. "Yet people just keep on using it, presumably because its message is one they want to promote."

The original statistic dates to at least 1995, when it was mentioned in the United Nations Human Development Report. The report warned about rising disparities.

"The most persistent of these has been gender disparity, despite a relentless struggle to equalize opportunities between women and men. The unfinished agenda for change is still considerable. Women still constitute 70 percent of the world's poor and two thirds of the world's illiterates."

The 70 percent figure shows up a couple of times in the 205-page report but not in any of the report’s statistical tables. In fact, staff at the United Nations Development Programme said they no longer use it.

Experts told us they’re not sure what the real figure is, but that it’s likely lower than 70 percent.

"Its not easy to say how many women are poor because data on poverty are typically constructed on a household basis," said Diane Elson, professor of sociology at the University of Essex.

In other words, surveys don’t count how many women and men live in each household. Statisticians, some within the United Nations itself, began debunking the 70 percent figure as early as 1998 -- just three years after it gained prominence.

Sylvia Chant, professor of development geography at the London School of Economics, pointed us to 2002 data from the Economic Commission for Latin America and the Caribbean. In Latin American countries, by a slight margin, women were more likely to live in poverty in rural areas. But the reverse was sometimes true in cities.

"In 10 out of 17 countries, the proportion of men in poverty is actually on a par with or slightly higher than women," Chant wrote in 2008. "Women are nowhere near the level of 70 percent of people in income poverty as popularly expounded."

A 2001 analysis of 10 developing countries largely found no statistically significant differences. Where there was a gap, in every country but one, it was very narrow, and sometimes, as in the Latin America survey, men outnumbered women in poverty.

Chant said Fiorina’s claim is no more right today than when it first emerged.

Green, the Oxfam adviser, agreed.

"It was wrong then, and remains wrong," Green said.

One note: While we don’t have a worldwide figure, we can use Census Bureau data to come up one for the United States. According to the most recent data, females account for 55 percent of Americans living in poverty.

Our ruling

Fiorina said that women account for 70 percent of the people in the world who live in poverty. She provided no support for the claim, nor does any seem to exist. We contacted the international bodies that rely on such statistics, and they told us they do not have the data to back up the claim. Independent experts echoed that point.

At least in Latin America and the United States, the data suggest a much lower figure. We rate this claim False.
