In my research at MIT, I need to find a credible histogram of the 
frequency of human (face to face) daily contacts for a representative 
sample of the USA.  Example:  10 % of the population interact with 5 
or fewer people per day.  5% interact with over 100.  etc.  An 
'interaction' can be a transaction with a sales clerk, selling a 
subway token,  having breakfast with your spouse, meeting with a 
student, etc.

While I have explored social network literature, I can't seem to find 
something this simple and yet fundamental.  Are you aware of such 

Thanks for your help!
