Re: [CTPP] An Alternative to Access ACS 5-year Block Group Data

Hi All, I have used the AS Alchemist and I too like the interface. I was not able to successfully create census tract or blockgroup results. I was wondering if someone else has experienced this and was able to work around it.

I just tested ACS Achemist that was developed by Azavea & Temple University and I think it's easy to use. But keep in mind that only ACS 2005-2009 and ACS 2006-2010 data are available in the ACS Alchemist. If you are looking for 1-year or 3-year data, you still need Census Bureau data access tools including American Fact finder and DataFerrett. ACS Achemist is an open source tool that enables the extraction of ACS 2005-2009 and ACS 2006-2010 data on different level of geographic aggregation, i.e., counties, county sub-division, tracts, blockgroups, etc. . The user interface is very straightforward and is a simple step-by-step process. The thing I like most is that output is saved as the shapefile and you can process your data in the GIS. The think I like least is that uses will have to create a variable file to define which data they want to get. The sample of a variable file can be find in the readme document which is included in the software installation package, but I attached one here for your convenience.
