Assemble the data in Excel, extracting values from the appropriate ArcView .dbf file by copying desired cells to a temporary Excel Sheet. This entails the use <control><c> (to copy multiple cells for transfer) and of 'Paste Special' with the "Transpose" option (to turn horizontally-arrayed data into single vertical columns). Male values can be made into negative values (so that they will display on the left side of the pyramid) by multiplying cells in the column by -1.
An example of how the completed dataset should look in Excel is as follows:
