2009-2013

Why is this data from 2009–2013 instead of just 2013?

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 2009–2013 describe average conditions reported during the period of January 2009 – December 2013.

How do I write about the 2009–2013 data in a grant report?

Here are some examples of how you can write about this data in a grant report:

“Looking across the five years from 2009 to 2013, the Census Bureau estimates that X% of residents had a high school education or higher…”

“In the five years following 2009, neighborhood statistical area X has experienced a poverty rate of…”

“From 2009 to 2013, X% of residents reported having a commute of X minutes or more to work…”
