A.3 Methodology for the State‐Level Analysis
The first step in preparing the state-level analysis was to derive shares of production by
state for each of the producing industry segments and for the downstream wholesale
and retail industries. National level direct production is then allocated to the state level
using employment shares taken from the BLS Census of Employment and Wages (CEW)

for both the upstream and the downstream analysis.
In order to calculate the indirect and induced impacts of production, we use the IMPLAN
system. National industry relationships are converted to a regional level using region-
specific information on trade flows, employment, and differences in the ratio of value
added to output. This results in an input-output matrix which is more representative of the
target state, metro area, or other defined region. When calculating indirect and induced
impacts, IMPLAN makes use of Regional Purchase Coefficients (RPC's). These RPC's
measure the proportion of activity that is sourced from within the state or region which is
the focus of the study. Products sourced from outside the state do not provide any
indirect or induced spending impacts.
Upon purchasing an IMPLAN package, it is accessed via the web. For this project, we
used the packages consisting of State Total Files. As mentioned above, national level
direct output is shared to the states using BLS CEW data, to obtain the state-level direct
output drivers. IMPLAN is then used to calculate indirect and induced output,
employment, value added and earnings.
