That pesky pay gap--"The report was chock full of evidence of how much has changed for women these past few decades, as the percentage of working women has gone up.

The number of working women with a college degree has risen sharply since 1970, as has the share of women who work in professional and management jobs.

The report was chock full of evidence of how much has changed for women these past few decades, as the percentage of working women has gone up.

But even as women have made strides, the pay gap between men and women has narrowed – but persisted – at every education level.

The report cites several factors that may explain the gap. For example, the report says that although women are more likely to work in a professional sector, they also are more likely to be in the lower-paying jobs in that category.

Women are also less likely to be in high-paying sectors of the economy, including the computer and engineering fields, as well as business and finance, according to the report.
