Esti- mates of total employment in the aggregates industry is just over 100,000 jobs. Assuming that the uncounted jobs are distributed across the states in proportional to the number of quarry employees and the multipliers are legitimately applied to these other types of employment, then the mag- nitude of the effects reported in Table 11 may be understated by about 66 percent. Table 12 offers the total jobs impacts after grossing up the quarry jobs figures for total aggregates industry employment. 30 We see that the employment effects are much larger if we adjust the employment level upward to reflect industry esti- mates. For instance, the 1,831 quarry jobs in Alabama would rise to 3,050 total aggregates industry jobs. Applying the mul- tiplier of 2.34, the total jobs in the state resulting from the aggregates industry is 7,143 jobs. In Texas, the total employ- ment impact of the industry rises from 11,506 to 19,169 statewide jobs. County-Level Effects of the Aggregates Industry The aggregates industry operates in every state. Given the high cost of transportation, quarries must be geographically disperse, and thus operate in a large number of the nation's counties. In fact, 90 percent of aggregates are consumed within 50 miles of the place of extraction. 31 Since much of the economic impact is based on induced effects, the economic impact at the county level will be much smaller than either the state or national multipliers. While other areas are certain to benefit from the economic activity of the aggregates indus- try in any one county, the county level economic impacts do not include these extra-regional effects. To determine the county level economic impacts, and to see how they may vary across counties, we estimated the multipliers for three coun- ties: (1) Larimer County, Colo.; (2) Lancaster County, Pa.; and (3) Talladega County, Ala. To quantify the economic effects of a quarry operation, we compare two states of the county economy: one with active quarry operations to a hypothetical alternative of one without active operations. Table 13 sum- marizes the key results. In Larimer County, the aggregates industry produces total earn- ings for the county of $13 million. About $8.6 million of these earnings come directly from quarry operations (66 percent of the total); $1.8 million from direct effects (multiplier = 0.21); $0.3 million from indirect effects (0.04); and $2.28 million from induced effects (0.26). The aggregates industry supports 341 jobs, with 241 being aggregate industry jobs. The remainder of jobs includes a direct effect of 32 jobs (0.13); an indirect effect of 8 jobs (0.03); and an induced effect of 59 jobs (0.24). The total jobs multiplier for quarry operations is 1.4 for the county. Local, state and federal governments each benefit from approximately $450,000 in tax revenue.
