I'd use the 'present continuous/progressive' or 'present perfect (continuous/progressive)'.
However, if it were "The total number of people accessing the Internet ... each year from 2009 to 2012", for example, I'd use the 'past simple'. It's because it refers to the past event. (I'm not sure if the '... women to have accessed the Internet' part in #1 refers to the past. I'm not familiar with the 'perfect infinitive' used here.)
