Over the last five years, the percentage of women professionals in the industry increased from 32% to 36%, according to survey results. However, the survey found that at comparable levels of experience significantly more men achieve senior level positions than women.

Comparing women and men with more than 20 years of experience in the industry, 44% of men held the title president, chief executive officer or chief financial officer, while only 23% of women held those titles. Women were much more likely than men to have positions of vice president or below, according to the survey.

More than one-third of the respondents--including both men and women--earned more than $150,000 in 2004, and 18% earned more than $250,000. However, while 58% of the men reported incomes of $150,000 or higher, only 24% of the women reported incomes of $150,000 or higher.
