ACS Migration Flow User Note: Omission of MCD Flows within Same County for 2005-2009 5-year ACS

2009

The 2005-2009 5-year ACS County/MCD-to-County/MCD Migration Flow tables issued on March 28, 2012 did not included records for movers between minor civil divisions within the same county. The “Inflow” and “Outflow” Excel and “All flows” text files now include those records.
