Hi Kate,
There are a couple things you can do ehre:
1. Create a Smart List with the "SFDC Type" filter. Select Contact on that filter and you will get a list of contacts as well as a total number.
2. Create a Lead Performance Report in Analytics. In this report, go to the Setup tab and edit the "Group Leads by" option. Select "SFDC Type" here is well and your report will show the total leads with different SFDC Types. (You will want to change the Date of Activity to "All Time" as well).
Both these options will update everytime you view them.
Will
