Dear Steven,

This is an update 2002 of the figures for 2000 provided in my paper "The
Mutual Information of University-Industry-Government Relations: An Indicator
of the Triple Helix Dynamics," Scientometrics 58(2), 2003, 445-467. See that
paper for similar figures for 2000 and for the methodology. The data is
statistical (i.e., with errors).

With kind regards,

Loet
