Census And ACS Data

The U.S. Census generates two main sources of demographic data, the Decennial Census and the American Community Survey (ACS).  The Decennial Census questionnaire asks basic questions of every resident of the United States every ten years, while the ACS questionnaire asks more detailed questions to a small sample of residents on a rolling annual basis. 

Resources for using ACS and Census products:

• United States Census Bureau
• Using American Community Survey Data
• ACS Statistical Significance Calculator . A spreadsheet that determines whether two estimates are statistically significant and calculates margins of error for multiple estimates, ratios, or proportions.

Rhode Island Statewide Planning staff can connect you to the Census and ACS data that you need. Please contact Vincent Flood with your questions.
