Owing to an error introduced during the production process, the word ‘impact’ was replaced incorrectly with the word ‘affect’ in the following two sentences (the correct versions of both sentences appear here).

2. Section heading: “Male or female? Two distinct categories or continuum?” (page 5)

“The report will have significant impact.”
