somewhat smaller than the number of awards, because the same site may receive multiple awards and competitive supplements. NIH does not track the number of centers, but the committee estimates that the unduplicated number of entities with center awards is approximately 1,050 after supplements and multiple awards are accounted for.
Figure 2-1 graphically displays the number of center grants awarded in each state in FY2002. There were center grants in every state. California, with 179, was the state holding the most center grants in FY2002, followed by Massachusetts with 97. The median number of center awards among the states was 16. This distribution is generally in line with the overall distribution of NIH extramural awards of all kinds.
Funding for center grants has generally increased in line with the overall NIH budget in recent years, constituting between 8 percent and 9 percent of the total NIH budget during the 1992 to 2003 period (Figure 2-2). In FY2002 the average center grant was $1.9 million a year. The range spanned three orders of magnitude however, from $55 thousand to $56 million, and the median annual center grant amount was only $1.3 million.
The FY2004 budget request sought an increase of $167 million to fund 1,237 center grants in FY2004 (see Table 2-1). If the proposed budget
