of assumptions are, in fact, to happen. The baseline concept, in 



simplest terms, means that a particular set of projections is selected as 



a base against which other projections are compared or analyzed a'S 

 alternatives. They should not, however, be viewed as quotas or con- 

 straints that must be met in the planning process. 



Projections of population, employment, and income are shown in tables 2, 

 3, and 4.
