"From 2000 to 2015, federal funds comprised between 29.9 and 40.8 percent of all Texas state revenue, and averaged about 34 percent (Exhibit 2). The federal share in all states tends to rise during recessionary periods and decline in better economic times. In each year of the period, however, Texas’ reliance on federal funds was higher than the average among states."
