    Hi Wen, Thank you for your forum post. If it is helpful, I have provided the following link that contains information about how our Employment data is derived and the sources that it is generated from: http://implan.com/index.php?option=com_content&view=article&id=414&Itemid=1878#employment-output-value-added-data If you do not mind sharing the specific industries and which other data sources you are referring to; we can better address your question.

    I'm looking at the traveler accommodation industry (NAICS 7211) in new york city and new york state using QCEW and CES. I know there's no industry in IMPLAN code that is exactly the same so I used industries with Implan codes 499 and 500. Even when I included both 499 and 500, the employment levels were much lower than what I found on QCEW/CES when looking at both the City and the State. Looking at the method in which Implan data is derived, it seems like employment levels are usually inflated if anything since it uses multiple sources.

    [attachment=676]h1445e70.xlsx[/attachment] Hi. While you are correct that IMPLAN employment figures generally start off larger than CEW figures, due to the addition of proprietors, a proportion of some sectors’ activity (employment, output, income, etc.) later gets reclassified into other sectors. This follows the BEA “re=definitions” practice and is designed to reassign products from producing industries in which they are secondary product, to the industries where those products are primary. Sector 499 (NAICS 721110 and 721120) happens to be one of the most redefined sectors. Consider a hotel in Las Vegas which has a casino, restaurant, gift shop, and concert stage. This hotel would not be very well represented by the production function, income per worker ratio, output per worker ratio, etc. of the hotel and motel sector. Thus, using the national re-definitions table from the BEA, we take certain small portions of this industry’s activity and “redefine” them to other appropriate sectors such as Gambling (495), Restaurants (503), various Retail, Performing Arts (488), etc. In the attached spreadsheet you can see how the Sector is split. The first column represents the Sector in IMPLAN the second column the Sector to which it is redefined, and the third column the coefficient of the total factor (Employment, Value Added, Output) that is redefined to that Sector. Please let us know if you have additional questions.
