4. 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).

5. 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.

9. 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.
