Calculating MOEs from derived ACS estimates

Mark Mather over 11 years ago

Over the years, we have heard from a lot of people interested in getting an easy-to-use tool that would help people calculate margins of error from derived ACS data (e.g., data combined across categories or geographies). There are several organizations that have developed some basic applications that might be useful. Here are the links:

If you are using a different application in your organization, feel free to post it here.

Excellent- 0-10%
Good- 10-30%
Fair- 30-60%
Poor- >61%

For groups of estimates (such as all of the Census Tracts in a county:

High- >80% of geographies' CV
Medium- 60-80% of geographies' CV
