Note: the smallest geographic unit will be census tract (2000 geography). Block Group data will be released later in Summary File format. From: Erlbaum, Nathan (DOT) [mailto:nerlbaum@dot.state.ny.us] Sent: Tuesday, December 07, 2010 5:01 AM Subject: FW: ACS 2005-09 comparisons with 2000 SF3 FYI. This may help next week when the 5-year ACS data are released. It appears that the Census Bureau has updated its guidelines for comparing the 5-year 2005-09 ACS data to 2000 data. When I checked this link today (http://www.census.gov/acs/www/guidance_for_data_users/comparing_2009/), I noticed that it included the 5-year data, which had been missing when I last checked just a week or so ago. Also, the Bureau provides a variable-specific drill-down tool here: http://www.census.gov/acs/www/guidance_for_data_users/2009_table_comparisons / Pretty neat.
