Do you dream of a single source for your data needs? Unfortunately, it doesn’t exist. We’re all stuck in the same “hobbling together data from various sources” boat. However, the REP can help you find the best, most versatile, and user-friendly sources of data. Currently, our resources are slightly California-centric; that’s our service area after all. If you have region-specific resources please share them with us as we would love to broaden our scope. Any suggestions, additions, or comments? Have a great site or article that you want to share? We would love to hear from you! Please use the “Contact the REP” button on the right.

General Data and Demographic Resources

American FactFinder

  • Site Summary: American FactFinder is the portal to U.S Census Bureau data. Although decennial census data is the most complete, you may be able to find more up-to-date data using the American Community Survey.
  • Suggested Uses: Cenus Bureau data can be used for just about anything with the added advantage that citing to a federal agency gives your presentation a unique degree of credibility. One word of caution, American FactFinder has a learning curve. This curve is rather steep if you are learing how to access and compile customized data tables.
  • Tips and Tricks:
    • By selecting the “custom table” option you can specify the exact datasets that you want to view.
    • If you need to perform computations using Census data you should cut and paste dataset outputs into an Excel document and run the calculations using Excel. This will save you a lot of time in the long run, especially if you decide that you want to change your calculations.
    • If you are really in a bind and need to do some mapping but don’t have access to a mapping application, you can print a map of census tracts in the desired region and then print data sets for those census tracts. Compare data to the correct census tract to get a picture of patterns in the region. This is a highly inefficient method of last resort.
    • Don’t forget that the Census Bureau publishes various comprehensive studies for each decennial Census. These reports are available in the Census Bureau Publications Section.

2000 Census Data & Data Extraction Tools

American Factfinder, although useful for the casual user, cannot meet the demands of advanced Census data users. In the end, most advanced users who cannot afford user-friendly proprietary data collections will find themselves at the Bureau’s ftp site.

Up until mid-2007, many data freaks went through all sort of complicated machinations to obtain the data that they wanted at the right summary level from the Bureau’s FTP datasets. No more! Professor Ralston has rescued us from the morass of Access templates and tedious American FactFinder mass data requests by providing GISTools freeware.

What are they: Professor Ralston developed four programs that allow people to easily obtain Census 2000 data from the SF1-SF4 files for any summary level (i.e. block, tract, city, county, state, etc.)

  • When do I use them: The REP suggests using these tools if you need Census 2000 data for presentations, research, or mapping. They are particularly helpful if you need data at the block group or block summary level.
  • How do I use them: These tools are super user-friendly. Step 1: Download the zip files containing the Census 2000 data from the Bureau’s ftp site. Step 2: Download the appropriate file for your data. There is one geo file for SF1-SF4 files for each state. It’s normally at the very bottom of the folder with the zip files for the summary file. For instance, at the bottom of the folder for California SF1 data there is a file named cageo_uf1.zip. Step 3: Download the tool. There is a different program for each summary file (i.e. 1-4). Step 4: Follow the instructions in the user manual that is available for download from the same site that you got the program from.

NOTE: The Sacramento SF3 dataset at the Block Group summary level has been removed from this site. That dataset and similar datasets are now easily obtainable using GISTools.
