516 Industry Codes
I am planning on buying new data from IMPLAN to update a project with an established methodology which had used pre-2000 IMPLAN data. In order to not change the methods, we want to make a bridge from the classifications of the newest data back to the old classifications since the SIC/NAICS codes have changed. Our old data had 516 numbers. I only find that IMPLAN used 528 or 509. We have several data sources to cross with (IMPLAN numbers, SIC, and what I believe is BEA), but none of them match anything that I can find.
As an example:
ID# 2, BEA 1020001, SIC 0252 - Eggs
ID# 3, BEA 1020002, SIC 0251 - Poultry
In neither 528 or 509 are Eggs and Poultry separate yet they are in our database. A direct comparison with SIC is also not possible because some IMPLAN numbers split the SIC numbers.
ID# 4, BEA 1030101, SIC 0214pt - Sheep
ID# 8, BEA 1030202, SIC 0214pt - Wool
This was originally purchased from IMPLAN and we are hoping to get a bridge table that will match what we have. Is there anything available that can do this?

Hello Erin, Unfortunately we have never produced a 516 Sector Model. However since the Model can be edited, we are suspecting that it may be that someone who had previously worked with your firm had taken external data and made splits from some of the aggregated 509 Sectors, as this is not an uncommon practice when people have the data to split a IMPLAN Sector into more descriptive Sectors. Our best suggestion would thus be to see if you can find any documentation from the first Model's setup to see if you determine what data sets were used by the analyst at that time to create a 516 Sector SAM so that you could find comparable current data sets with which to make these splits now. We apologize that we don't have any further thoughts to offer in regards to the Sector splits you have in your Model. However, if you need assistance with bridging from your Model to the current one or if you need assistance splitting Sectors in the Study Area Data please let us know and we will be glad to help with this.
