My users want to look at the spatial distribution of the percent of households that receive a particular government benefit, within block groups, across Boulder County, in 2010, and plan a marketing campaign for 2012. County wide, we have 404 households receiving this benefit out of 27,853 eligible households. How can I calculate the level of confidence we should have using this 2010 data to predict the pattern in 2012?
