Impose Data Reliability Threshold for Census-related Data #14

Open tiernanmartin opened 5 years ago

tiernanmartin commented 5 years ago

Tracts with no or extremely small populations should be identified and excluded from the analysis.

A reasonable threshold for King County might be 1,250 (total population) - which would exclude one unpopulated tract and one sparsely populated tract:

Total Population, 2007-2011

acs_11_5yr_b01003

Total Population, 2013-2017

acs_17_5yr_b01003

Note: this practice of excluding low-population tracts improves the reliability of the analysis.
