I’m trying to break down the metro area destinations for people of a certain race who migrated from a specific state (
migplace) in the 2013-2017 ACS extract. I’m getting a large chunk of people in “Not identifiable” areas, however.
Does this refer to people moving to places not defined as metro areas or to people who may be in a metro area but we don’t know about or both? Trying to decide if the metros that are reported have too small of a percentage of people compared to the NA category.
Here’s a screenshot of my results. I’m using the SDA interface:
I also ran the query for the
metro row variable, and the indeterminable and not-in-a-metro estimates don’t quite add up to the total reported in the “not in identifiable area” (23.3 vs 26.6)
Am I better off not using the metro areas identified? What does it mean to have a “mixed” metropolitan status?
