As you glance through our annual Women in Business supplement (in this issue), you would be forgiven for thinking women are doing just fine in the workforce — but the gender gap persists.

Most would agree women’s roles in society and business have evolved dramatically in the last 100 years. In the early 1900s, just 18.8 percent of women worked outside the home. According to the 2010 census, that figure has now jumped to 47 percent. Women’s participation in the workforce increased by nearly 5 percent between 1970 and 1980 alone, and by over 3 percent in the next decade. The 1980s saw a number of “firsts” for women, including the first female Supreme Court justice and the first female astronaut. Women’s representation as accountants, pharmacists and physicians, veterinarians, lawyers and judges has increased dramatically.
