# How to count the occurence of M and F in a particular column , No. of male and female deaths?

how to command LaTeX to count occurence of M and F in a particular column of a table from first row to last row of a particular column? And also the number of Male Deaths and Number of Female Deaths, I know we can do manually counting visually if number of rows is small, but in the case of large number of rows visually counting may not be possible here I am ataching my table codes in latex. Thanking you in advance.

• Unrelated: Why have you put the tabular in math mode? – Torbjørn T. May 11 '17 at 9:53
• Sorry for putting tabular mode, I donot know much about the commands of the desired packages which command will be suitable for here to perform calculation. @TorbjørnT. – Biki Teron May 11 '17 at 9:56

A variant using datatool and some counters.

Here, if you place your table data in a \def, you can use the created macro \analyze to look for patterns. This macro employs the listofitems package to parse the data in your table, and count the results. Because the patterns are precisely specified, it relies on you the user applying space padding around the gender and death columns (that is & M & Y will not be interpreted the same as &M&Y).

That being said, the results of \analyze are stored in \males, \females, \maledeaths, and \femaledeaths, which can be later recalled.
