<br /> NOTE: Durham City comprises two small areas of Orange County, one each in Eno and Chapel Hill Townships. The total
<br /> population of both areas is 144 people. These people were included in their respective township totals.
<br /> Linear methodology:
<br /> Formula: Pt+ n = Pt + bn
<br /> where Pt = population in base year t;
<br /> Pt+n = projected population size at a future year, n units of time beyond base year t;
<br /> b = average increment of change in population size per unit of time; and
<br /> n = the number of time periods beyond base year t
<br /> The average increments were obtained by substracting 2000 from 2010 and 2010 from 2020 and dividing the sum of by 2.
<br /> Example: ((2000-2010)+(2010-2020))/2. The projections were done by adding the average increment(row 9)to the 2020 data
<br /> (row 7)and multiplying the result by the difference in the projection year and the most recent year of data (row 7), then dividing
<br /> that result by 10 (10 year projection increments). Example: 6,972 + (396 * (2030-2020)/10))= 6,923
<br /> Methodology taken from URBAN LAND USE PLANNING (p.125)found in Planning library.
<br /> Note: The 2000 population numbers for the Town of Chapel Hill, Chapel Hill Twp and Orange County have been corrected by the U.S.
<br /> Census Bureau. This worksheet reflects those changes.
