My name is Megan Cogburn and I am a Community Planner with the North Carolina Department of Transportation. My group is a part of the Project Development and Environmental Analysis branch and we are responsible for completing all of the NEPA documentation for bridge and highway projects statewide. Specifically, we prepare technical reports assessing potential project impacts on the human environment from the local/urban planning perspective. We currently use decennial Census data for our demographic analyses, however we are thinking of switching to use American Community Survey data to make our reports more current and since the American Community Survey has now replaced the traditional decennial Census long-form. However, it has come to our attention that ACS data is only available at the block group level for 5 Year Estimates (and not annually). Moreover, certain tables that were available for the 2000 Census are not available in the ACS 5 Year Estimates (such as household type by relationship, sex by employment status, and poverty status). Another glaring issue is that ACS 5 Year Estimates were just released in 2010, so there is no previous data to make historical comparisons. So, my question for the listserv is how other organizations are moving forward given the discrepancies between the two datasets. My group is trying to figure out where to get missing data, how to make historical comparisons, and also the best way to retrieve ACS 5-Year Estimates. A huge drawback for us is that we use block group data for multiple variables and this is only available for the 5 year estimates. In order to retrieve summary file data for block groups you have to use an Excel macro retrieval file that takes an extremely long time, download a massive file from their FTP site, or use the not so user friendly Data Ferret platform. Please advise!
