After 2000, the Census began collecting a lot of their data through an ongoing survey called the American Community Survey mailed to a small sample of households — instead of through their once–every–ten–year door–to–door survey. Now they pull together five years of American Community Surveys to have a large enough sample in any one neighborhood to provide estimates for that neighborhood. For this reason, data for 2006–2010 describe average conditions reported during the period of January 2006 – December 2010.
Here are some examples of how you can write about this data in a grant report:
“Looking across the five years from 2006 to 2010, the Census Bureau estimates that X% of residents had a high school education or higher…”
“In the five years following 2006, neighborhood statistical area X has experienced a poverty rate of…”
“From 2006 to 2010, X% of residents reported having a commute of X minutes or more to work…”
