Profile Variables
Population
– The total population of each NSA.
2012 population data was collected for each block group (NSA).
Source: U.S. Census Bureau, American Community Survey 2012 5-Year Estimates.
Population Growth
– Percent change in population from 2010 to 2012.
2010 and 2012 American Community Survey data on total population was collected for census
block groups in Chesapeake. The following equation was used:
2012 population – 2010 population
* 100 = % Change in MHI per census tract
2010 population
Please note, because some block group geographic boundaries shifted between 2000 and 2010,
data prior to 2010 could not be used for these calculations. Ideally, during the next study update,
a longer timeframe could be used for this variable.
