Data comparison (QCEW & IMPLAN)
Hi!
I am using the 2010 model of Harris County, Texas to estimate impacts for Sector 411: Hotels. However, IMPLAN says the employment in this industry is around 11,000 while QCEW data for Harris County in 2010 shows employment of 15,200. I was hoping you could help me explain this discrepancy.
I looked into the IMPLAN data sources data set definitions reference files on your website but it doesn't seem that any of the normal explanations apply in this case. Please advise.
Thanks,
Katie

We redefine industry data so that it conforms with the definitions of the BEA production functions. See this forum thread: http://implan.com/V4/index.php?option=com_kunena&func=view&catid=80&id=13424&Itemid=35#13426 -
Great, that clears up the employment question. However, we pulled accommodations and food service industry gross sales information for Harris County (2010) and found that number is much lower than the total output for industries 411, 412, and 413 in the base model ($7.4 billion versus $10.2 billion in IMPLAN). Since employees are being moved from a higher output/worker industry (hotels) to a lower output/worker industry (restaurants) in the force adjustment, I don't think this would result in a higher industry output estimate. Can you give me some insight on where these numbers are coming from and how we can account for this difference in industry sales? Thanks! Katie -
In response to your previous post, you are correct, I misunderstood. The redefinition only explains the employment and income problem you mention. We use National industry relationships to income for Hotel output. If your county's output to income is much lower than average, I suggest you edit the output in the study area to reflect that, I would also reduce proprietor and other property income proportionately. Is this Census data you are using for Harris County output? -
Thanks, Doug, for the clarification. We are using BLS QCEW data for employment and compensation and information. For our output estimate, we are using gross sales for the hospitality industry (accommodations and food services) as reported in the State of Texas 2010 sales tax report. -
Looking at the 2007 Economic Census for TX: http://factfinder2.census.gov/faces/tableservices/jsf/pages/productview.xhtml?pid=ECN_2007_US_00A1&prodType=table --- this link may not work without working through the factfinder menus. it shows that TX NAICs 721 is ~8.35 billion and IMPLAN sectors 411 and 412 are ~7.54 billion in 2010. It shows that TX NAICs 722 is ~35.1 billion and IMPLAN sector 413 is about 48.5 billion in 2010. If the growth is not high between 2007 and 2012 then it seems reasonable (with the redefinitions). How does the TX sales tax data compare to 2007 Census?
