Reusing survey data for annual analysis

Hi,

We collected employment numbers for an industry for different states in 2017 and ran contribution analysis using 2017 IMPLAN data. We are now trying to do this annually however doing survey every year is not feasible and is costly too. Do you suggest using same survey results (2017) to do annual analysis (for less than 5 years) is ok? I know there might be changes in an economy from one year to another but thinking survey cost and time what strategies can be applied to reuse the survey data to run annual analysis?

Thanks,

Hello,

What I would recommend here is to utilize the same Group Dollar Year for each of the annual analyses, and then pull the results in the year your are trying to analyze. For example: For the 2018 analysis, the Group Dollar Year would be set to 2017 on the Impacts page. Then on the Results page set your Dollar Year to 2018 within the filters in order to properly account for inflation/deflation over time.

Hope this helps!

Thanks for the response!

That is what I was thinking first but that will just account for inflation and employment number will remain same. This might raise questions of "how can jobs remain flat" over years. The approach will just report dollar value in todays date and does not account for any ups or downs.

Without knowing your explicit Event Values it is impossible to know for sure - but utilizing the same inputs on the Impacts page should yield differing employment results if you pull them in different Dollar Years. Either way, these differences would only be marginal as certainly is expected when utilizing the same inputs across years.

Best,
