5. Perfect Population Projections Inc. (PPP) has entered into a contract with the city
of Popular, Pennsylvania, to project the future population of the city. Popular has
become a popular place in recent years as indicated by the following data:
Total Total Basic Nonbasic
Year Population Employment Employment Employment
2005 50,000 25,000 6,250 18,750
2006 53,000 26,500 6,625 19,875
2007 57,000 28,500 7,125 21,375
2008 65,000 32,500 8,125 24,375
2009 70,000 35,000 8,750 26,250
2010 ? ? 9,000* ?
*Estimated from surveys
The contract states that PPP must project Popular’s population for the year 2005
using both a simple linear method and an economic base analysis. The ratio of
population to total employment is 2.0833.

Solution: Using a simple linear method, the growth trend in the population would
be extended (extrapolated) one year. The extrapolation could be done graphically,
Alternatively, it could be done by simple linear regression, resulting in an
estimated annual incremental growth of 5,900. Thus the population by linear
