Each year a variety of data sources are compiled to create the IMPLAN datasets. Most of IMPLAN's Industries are based on definitions put forth by the Bureau of Economic Analysis (BEA). For those industries, IMPLAN provides a crosswalk between NAICS codes and IMPLAN Industries. Among our main data sources are the following:
CEW: Census of Employment and Wages (Bureau of Labor Statistics - BLS)
REA: Regional Economic Accounts (Bureau of Economic Analysis - BEA)
CBP: County Business Patterns (Census Bureau)
NIPA: National Income and Product Accounts (Bureau of Economic Analysis - BEA)
IMPLAN data come from various sources, in a variety of Industry schemes, sometimes with differing definition frameworks, and most with non-disclosures. IMPLAN data is available at the zip code, congressional district, county, metropolitan statistical area, state and national level. IMPLAN constructs a complete database and adds value to the available data by:
- Creating new datasets each year
- Providing estimates for non-disclosed data
- Providing estimates for non-Census years
- Providing estimates at finer geographic and sectoral scales
- Providing inter-county trade flow data, which allows for Multi-Regional I/O analysis
- Reconciliation of multiple data sources
- Compiling the data together in a consistent format
