How many laws...

[A18]

Does a single Congress usually pass in its two year duration?

Too many.

All I could find from a very very brief Googling was
http://usgovinfo.about.com/blnewlaws99.htm which says the 1st session of the 106th Congress passed 104 bills which were signed by President Clinton.  I don't recall Clinton vetoing a lot of bills, so based on this single datapoint we get 208 new laws for every Congress. 

However that number seemed low to me so I went to http://thomas.loc.gov/bss/d108/d108laws.html

It's looking more like 458 public laws were made in the 108th Congress.

At this point, I'm thinking my first answer was correct -- Too many.

It looks like the 108th Congress enacted 428 public laws. And four private laws, whatever that means.

The 107th Congress passed 377 public and 6 private.

Private laws act with referrence to specific named persons, and thus are not of general application.  A common use of them today is to grant citizenship or provide for speedy resolution of a civil claim against the United States without it having to go through the courts.
