|IMPLAN Data Components - Detailed|
IMPLAN's annual datasets provide a complete set of balanced social accounting matrices (SAMs) for every zip-code, county, and state in the U.S. These SAMs provide a complete picture of the economy and can be used to generate predictive input-output (I-O) multipliers for estimating economic impacts.
Figure 1: Regional IMPLAN Data
Data that describe the local region can be divided up into several categories; descriptive data; industry specific value added, output and employment; institutional demands; transfers data; and demographic data.
Data Year – each data set describes the local region for a specific calendar year
Population – number of region residents
Land Area – squares miles of land area, which is net of large bodies of water
Industry data – the number of industry sectors described by the data below is based on the current sectoring scheme. The data set’s scheme is based on the
most current BEA I-O benchmark table, so it is tied to NAICs, except for government, special sectors and construction (which is based on Census structure
Output – the value of industry production in producer prices
Employment – annual average full-time/part-time jobs. This includes both wage and salary and self-employment
Employee Compensation – one of the factors of production. It includes wage and salary income plus benefits and employer paid taxes.
Proprietor Income – self-employment income including capital consumption allowance.
Other Property Income – corporate profits, rent, interest and capital consumption allowance.
Indirect Business Taxes – essentially all payments to government except for payroll taxes and end of year corporate income taxes. This includes sales tax,
excise tax, fees, fines, licenses, and property tax.
Institutional Demand – the institutions are the components of final demand that consume commodities and drive the local economy. The sectoring scheme
that describes the commodities consumed by institutions is based on the BEA I-O benchmark table.
Households – the consumption of goods and services by households is traditionally known as Personal Consumption Expenditures (PCE). IMPLAN has nine categories of household institutions distinguished by income class.
State and Local Government Education – the operational spending pattern of all levels of public education, from pre-K to higher-ed.
State and Local Government Non-education – the operational spending pattern of all other divisions of administrative state and local government. This includes legislature, police, fire, hospitals, prisons, etc. This does not include market driven (enterprise) activities such as sewer, water, power and public transportation.
State and Local Government Investment – the new construction and capital goods expenditures by all levels of state and local government.
State and Local Government Sales – note that while the BEA denotes sales by institutions as a negative purchase, IMPLAN treats it as a contribution to commodity supply. These are the goods and services sold by government administrative sectors. It includes hospital care, higher education, and timber.
Federal Defense – the operational spending pattern of defense agencies which include the military services and Coast Guard.
Federal non-Defense – the operational spending pattern of all other administrative Federal agencies.
Federal Investment – the new construction and capital goods expenditures by all Federal government agencies.
Federal Sales – note that while the BEA denotes sales by institutions as a negative purchase, IMPLAN treats it as a contribution to commodity supply. These are the goods and services sold by government administrative sectors. It includes timber, lodging and mineral leases.
Capital - the new construction and capital goods expenditures by all non-government (private) investors.
Inventory Purchases – net movement of goods into inventory.
Inventory Sales – note that while the BEA denotes sales by institutions as a negative purchase, IMPLAN treats it as a contribution to commodity supply. This is the net movement of goods out of inventory.
Foreign Exports – the export of commodities to destinations outside of the US.
Foreign Imports – note that while the BEA denotes sales by institutions as a negative purchase, IMPLAN treats it as a contribution to commodity supply. This is the import of commodities from origins outside of the US.
Trade Flows – for each data year, MIG runs a double-constrained gravity model to estimate the county-to-county trade flows for each commodity in the IMPLAN sector scheme. This is the data that allows creation of the version 3 multi-region I-O models. Note that domestic imports are used by the software to create multipliers and MRIO models, but access to the data itself is not granted under the standard user license.
Domestic Import – the import of goods and services from every county to the region being modeled. This includes locally produced commodities used by local demand –ie, imports from itself to itself.
Domestic Export – the export of goods and services from the region to every county.
Transfer Payment – these are the payment by factors to institutions, as well as, institution payments to institutions. These are generally scalar values as we do not have the industry and commodity sectors involved as in the earlier data items. These payments include the transfer of income to households and government, payment of taxes by households, receipt of retirement capital by households and so on. These data are an extension to I-O accounts and make it possible to create the various forms of the Type SAM multiplier.
National level data that is adjusted and used in every regional model.
Absorption Matrix – the industry purchase of intermediate goods and services (commodities) in coefficient form.
By-products Matrix – the industry production of commodities in coefficient form. Using the region’s industry output this matrix defines the total value of commodity production by industries.
Deflators – output indexes of inflation for each commodity (with the current data year index set at 1.00) is provided along with a similar index for GDP, which are applied to factors. This is not used to create the social accounts or multipliers but can be necessary for impact analysis.
Margins – a set of ratios applied to purchaser value that will convert sales to producer values. This is not used to create the social accounts or multipliers but can be necessary for impact analysis.
Econometric RPCs – an econometric equation for each commodity, which can be used to estimate trade flows for those models where the gravity model based trade flows are not possible or desired. These would be used for zip code models or possibly for models that have been customized by the user.
The original study area data, industry by commodity social accounts, industry by industry social accounts, multipliers and impacts are all available to the user in IMPLAN reports. This includes data that is derived using the data described above.
