Sample Size Matters by By Lynn Wombold, ESRI Chief Demographer
Someone who knows a lot more about these things than I noted that "these are issues known to most folks heavily involved with the ACS." Demographic groups have been "encouraging the Census Bureau to find ways to increase the ACS sample from 3 million addresses to the originally (back in the early '90s) 3 percent sample. Given the current federal budget situation, the need for the Census Bureau to convert 2010 Census NRFU to paper, etc. we are not likely to see any increase in the ACS data collection budget until sometime after the 2010 Census."
