[CTPP] ACS 3-year 20,000 pop threshold

[Ed Christopher]

Elaine Murakami (FHWA) just passed me a powerpoint slide that I have to 
  share.  It was developed in reply to a request by Alan Pisarski at the 
CTPP Oversight Board meeting last week.  Alan had wanted to SEE where 
the counties that DID NOT MEET the 3-year 20,000 population threshold 
were.  Elaine worked with Supin Yoder also of FHWA and used a list of 
counties provided by Melissa Chiu of the Census Bureau to make the map. 
  Besides being very informative it is possible to zoom into the map if 
you want to look at a particular state or area.  I have seen lists of 
Counties before but seeing the map was quite revealing.

When looking at the map and considering your areas, keep in mind that 
even if a county has met the population threshold of 20,000 it does not 
mean that all the tables for that county will be available in the ACS 
3-year tables.  I know this point has frustrated many users.
