§ 154.01 INTRODUCTION.
   (A)   The fundamental purpose of all public, physical improvements in a community is to serve the needs or desires of the residents. It follows, therefore that the preparation of a sound community plan require the study of past population trends, present conditions, and an estimate of the probable size, distribution, and other characteristics of the future residents. Population analysis also enables one to see, to a degree, the type and character of people with which one is dealing so proposed improvements or changes will be on a sound, social basis.
   (B)   Studies of the population within the planning area are essential to estimate how much land will be necessary for future uses and activities; to establish standards for various public facilities and services, streets, sewers, water supply, schools, and parks; and to serve as a guide in determining the approximate location and size of business and industrial district. Estimates of future probabilities with respect to numbers, distribution in the community, and age composition are essential to avoid prematurely opening up land for urban development, entailing excessive costs of public services and facilities; ensure within practicable limits that public facilities such as schools, recreation areas, water supply, sewage facilities, and others, will be of sufficient size; and prevent mislocating or overextending business or industrial zones. All of these are becoming increasingly common mistakes in both urban and non-urban areas. The table below shows the population trend from 1880-2000 for the planning area.
