3. Enrollment: Public & Charter Schools Private (Parochial) Independent Demography The Economy

4. Enrollment: Public & Charter Schools Private (Parochial) Independent Demography The Economy

5. Assumptions  Demography and Economics Matter –Probably more than good marketing and admission practices  Demographic, Economic and Socio-graphic predictions are only as good as the set of assumptions on which they are based (baby boomlet error).  Economic and Demographic trends are relational.  When the Economy and Demography are pointed in the same direction (good or bad) they are compounding.  It will get either better or worse, eventually…both economic and demographic trends are cyclical… – (but only somewhat predicable).

6. More Assumptions  All Demography that matters is local…even to a large extent for boarding schools.  The location of a school can either insulate it from negative impacts of national demographic and economic downturns, or intensify the effects.  Schools which may feel isolated from national demographic or economic trends, can still be indirectly affected by the Government’s reaction to the trends.  Demographic research is essential, and not necessarily difficult or expensive.

10. Z - Scores  A “Z – Score” is a score that is converted to a common scale where scores from sets of data with different units can be compared.  Z = (Raw Score – Mean of Group Scores) Standard Deviation  In other words…what is the ratio of the difference in this specific score from the group mean (average) to the standard deviation of this group.
