2013 Distressed or Underserved Nonmetropolitan Middle-Income Geographies Source
Information and Methodology
Note: At the time of the release of this file, the 2010 Census summary files for the island areas
American Samoa, Commonwealth of the Northern Mariana Islands, Guam, and U.S. Virgin Islands
are not yet available. Therefore, the initial release of the 2013 list will not contain any tracts from
these areas.
Poverty rate (Changes Annually)
Source: U.S. Census Bureau Small Area Income and Poverty Estimates (SAIPE), 2011. Variable
used was "Estimated percent of people of all ages in poverty". Note: Due to the U.S. Census
Bureau’s adoption of American Community Survey (ACS) data in the estimation procedure for
SAIPE, SAIPE data is now available with a two year lag from the year of the Distressed or
Underserved Tract List instead of the previous three year lag.
Population
Source: U.S. Census Bureau County Intercensal Estimates by County (for change between 2000
and 2010 populations and for change between 2005 and 2010 populations).
10 Year Population loss from 2000 to 2010 = (2010 population-2000 population)/2000 population
5 Year Population loss from 2005 to 2010 = (2010 population-2005 population)/2005 population
Note: At the time of the release of this file, the Domestic 5-year net migration provided by Census
2000 (PHC-T-22) Table 2 used in previous years is not available in the 2010 Census. Therefore the
formula for 5 year loss in population is used in its place.
Unemployment (Changes Annually)
Source: Bureau of Labor Statistics Local Area Unemployment Statistics, Labor Force Data by
County, 2012 Annual Averages
County unemployment rate = (Unemployment level)/(Labor Force)*100
National unemployment rate = (Total unemployment)/(Total labor force)*100
Note: BLS does not collect employment data for Kalawao County, Hawaii and considers it part of
Maui County. We assume unemployment data for Kalawao County is the same as that of Maui.

Low density
Source: U.S. Department of Agriculture Economic Research Service Urban Influence Codes,
2003.
Low density if Urban Influence code is 7, 10, 11 or 12
Note 1: The 2013 U.S. Department of Agriculture urban influence codes are based on the Office of
Management and Budget (OMB) Metropolitan Area delineations as of February 2013. Therefore the
2013 list will continue to use the 2003 urban influence codes. The new 2013 urban influence codes

will be adopted in the 2014 list to coincide with the 2014 FFIEC Census file’s adoption of the
February 2013 OMB delineations.
Note 2: Low density data was not available separately for Wrangell City and Borough, Petersburg,
and Prince of Wales-Hyder census area which were separated from Wrangell-Petersburg and Prince
of Wales-Quter Ketchikan census area in 2008. We assume low density data for Wrangell City and
Borough, Petersburg, and Prince of Wales-Hyder is the same as (or equivalent to) the 2003 data for
the Wrangell-Petersburg and Prince of Wales-Quter Ketchikan census area.
