Street maps of waste sites, street addresses and zip codes are important for tracking sub-county Census data.
Large university and public libraries usually have specialists in geography, maps, and computerized mapping (GIS). CD-ROM mapping programs often have a combination of environmental identifiers as well as census mapping.

Key factors to research: race, the elderly, poverty, unemployment, home value, ability to speak English, migration, vacancy rates. The Census does not cover deaths in a given year or individual disabilities.Notes on the data:
- Races are white, black, Asian, American Indian and other.
- Hispanic is not a race so is usually covered in a separate table.
- Labor force participation includes people who have jobs or want them. Reasons for not participating in the labor force include age, disability, family matters, retirement, school enrollment, etc.
- Unemployment is calculated by dividing the people who want jobs but don't have them by the labor force.
- Income is calculated for households (families, people living alone, people living together but not related), families (related by blood or marriage), individuals, and per capita (including children).
- Median = half below level and half above level; mean = average.
- Poverty rates are calculated by the Census Bureau using the family income and size of the family.

- Use the Chemical Scorecard, http://www.scorecard.org/ranking to obtain the street address of pollution site
(If using the Superfund National Priorities List, http://www.epa.gov/superfund/sites/index.htm, fiddle with Maps on Us, http://www.mapsonus.com/ or MapQuest, http://www.mapquest.com/, to get street names surrounding the site and a nearby street address.
- Search the street address in the Federal Financial Institutions Examination Council Geocode List, http://www.ffiec.gov/geocode/, to obtain the census tract number.
- Use the CIESIN MAPPING SERVICE Java Version 3.0, http://plue.sedac.ciesin.org/plue/ddviewer/ to map the census tracts. Note that this program identifies the tract number and data if you click on a tract.
- Go back to the Chemical Scorecard, http://www.scorecard.org/ranking for toxicity information and local lobbying contacts.
