Someone from Massachusetts: Did you leave me a phone message? I did
not get the correct phone number to return your call.
The 2006-2008 CTPP does NOT have any places or towns with less than
20,000 population. The 20,000 population threshold is a rule
established by the Census Bureau which limits the geographic units
tabulated when 3 years of ACS are pulled together. The threshold for
1-year ACS tabulations is 65,000 population. After 5 years of
accumulation, there is no geographic population threshold.
