The fact that nontrivial problems of aggregation arise, and that the microelements often turn out on closer examination to be unrealistic constructions, does not deprive them of explanatory and predictive value.

The Laplace Transform on Time Scales, the individuals included within some area—state, province, county, or nation. Recognizing only two units, population and individual, permits the construction of models that are readily expounded and understood. Demographers, following in the footsteps of Lotka and other predecessors, have worked hard to simplify this much-too-complex material.

Projection and Forecasting,vember, and the details of the count were published over the course of years. The census differs only in degree from stock market prices, which are hours old before they appear in the daily press. There are no exceptions—not even statistics of intentions—to the rule that all data are to some degree obsolete by the time they reach us.
