It's difficult to say. The last time we did survey research on procurement was in 1995. I tried to compare the two, and they're not directly comparable; however, in 1995 we found around 40% of SMEs at that point--though it was a more targeted survey--were actually selling to the federal government. In this one we're finding only 21% are. But I'd take that at face value for now. We have to do a little more digging to see if those numbers have actually gone down that dramatically or if it's more just because of the data sets we were using.
